How to get post body data from java jax-rs server - java

I followed a simple java server setup guide.
So i have something like this:
MyApp.java
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;
#ApplicationPath("/")
public class MyApplication extends Application {
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> h = new HashSet<>();
h.add( HelloWorld.class );
return h;
}
}
and HelloWord.java
import javax.servlet.annotation.MultipartConfig;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.Part;
import javax.ws.rs.*;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Request;
import java.io.IOException;
import java.util.*;
import java.util.stream.Collectors;
#Path("/helloworld")
public class HelloWorld {
#Context
private HttpServletRequest httpRequest;
#GET
#Produces("text/plain")
public String getClichedMessage() {
return "Hello, World!";
}
#POST
#Consumes()
#Produces("text/plain")
public String doThis(String x) {
System.out.println(x);
//....
}
}
The incoming request is of type
content-type = multipart/form-data; boundary=somerandstuff
and looks like :
--somerandstuff
Content-Disposition: form-data; name="somedata1"
data text 1here
--somerandstuff
Content-Disposition: form-data; name="somedata2"
more data text here
--somerandstuff
Content-Disposition: form-data; name="numberoffiles"
3
--somerandstuff
Content-Disposition: form-data; name="file1"; filename="firstfile"
Content-Type: application/octet-stream
{unreadable symbols thing here}
.
.
. 2 more files like above
How do I go about actually reading the data? I've tried many things and can't get it to work. I tried using httpRequest.getParameterMap() and httpRequest.getParameterNames() and printing everything but nothing prints. I can't seem to even access the post body data. The only things I can access are the headers using httpRequest.getHeaderNames().
What I want to do is store each file in a File object (or something similar) and then download it. How would i go about doing that? I've looked at a few posts on this topic but when I try implementing the solutions, they don't seem to work.

Ok so what you have is multipart data, which is most commonly used to send multiple files and metadata (or other data) along with those files. There is no standard JAX-RS support for multipart, but you are using Jersey (a JAX-RS implementation) and Jersey does have support for multipart. The first thing you need to do is add a new dependency to your pom.xml file
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.31</version>
</dependency>
The next thing you need to do is register this feature with your application. Since you are using an Application subclass, you would add the MultiPartFeature class to the classes in getClasses()
#ApplicationPath("/")
public class MyApplication extends Application {
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> h = new HashSet<>();
h.add(HelloWorld.class);
h.add(MultiPartFeature.class);
return h;
}
}
Now we can use this feature. In your resource method, what we will do is declare each part using Jersey's #FormDataParam annotation. As you can see in the multipart entity, each part has a name
Content-Disposition: form-data; name="somedata1"
Here the name of this part is somedata1. So we will add a parameter for this part. Also notice I will add #Consumes(MediaType.MULTIPART_FORM_DATA) as that is the content-type our method will be consuming.
#POST
#Path("upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response fileUpload(#FormDataParam("somedata1") String someData1) {
...
}
Based on what type of data is expected, that's how you will determine the parameter type. The type of somedata1 is just plain text, that's why I used a String. But the numeroffiles part is a number, so I can use an int for that part
public Response fileUpload(#FormDataParam("somedata1") String someData1,
#FormDataParam("numberoffiles") int numberOfFiles) {
...
}
The firtfile part is going to be a binary file. So what we can use an InputStream, File, or byte[] parameter. We can also add an additional parameter of type FormDataContentDisposition which will give us some info about this file. For this example, I will use an InputStream. Just google "how to save an InputStream to a file in Java"
public Response fileUpload(#FormDataParam("somedata1") String someData1,
#FormDataParam("numberoffiles") int numberOfFiles,
#FormDataParam("file1") InputStream firstFile,
#FormDataParam("file1") FormDataContentDisposition fdcd) {
...
String fileName = fdcd.getFileName();
}
UPDATE
If the number of files is unknown, instead of decalring all these separate parts, what you can do is just declare one parameter of type FormDataMultiPart and programmatically extract each part
public Response fileUpload(FormDataMultiPart multipart) {
Map<String,List<FormDataBodyPart>> bodyParts = multipart.getFields();
FormDataBodyPart someDataPart = multipart.getField("somedata1");
String someData = someDataPart.getValueAs(String.class);
}
You will need to traverse all the FormDataBodyParts and you use the bodyPart.getValueAs(Class) method to extract the data of the body part. For the files, you would use getValueAs(InputStream.class).
And that's pretty much it. That's how you work with multipart in Jersey. For more info, you can read the complete docs

spring.security.oauth2.resourceserver.opaquetoken.client-secret=dfdslksfkljweewrfsd
Added a class

List<String> roles = realm_access.getOrDefault("roles", Collections.emptyList());
List<GrantedAuthority> rolesAuthorities = roles.stream()
.map(SimpleGrantedAuthority::new)
.collect(Collectors.toList());
Set<GrantedAuthority> allAuthorities = new HashSet<>();
allAuthorities.addAll(principal.getAuthorities());
allAuthorities.addAll(rolesAuthorities);
return allAuthorities;
}
}
And the main class of the project
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.oauth2.resource.OAuth2ResourceServerProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.PropertySource;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.oauth2.server.resource.introspection.NimbusReactiveOpaqueTokenIntrospector;
import org.springframework.security.oauth2.server.resource.introspection.ReactiveOpaqueTokenIntrospector;
import ru.test.gw.oauth.resource.backresource.security.KeycloakReactiveTokenInstrospector;
#SpringBootApplication
//#PropertySource("classpath:quotes-application.properties")
#EnableWebFluxSecurity
public class BackresourceApplication {
public static void main(String[] args) {
SpringApplication.run(BackresourceApplication.class, args);
}
#Bean
public SpringOpaqueTokenIntrospector keycloakIntrospector(OAuth2ResourceServerProperties props) {
NimbusReactiveOpaqueTokenIntrospector delegate = new NimbusReactiveOpaqueTokenIntrospector(
props.getOpaquetoken().getIntrospectionUri(),
props.getOpaquetoken().getClientId(),
props.getOpaquetoken().getClientSecret());
return new KeycloakReactiveTokenInstrospector(delegate);
}
}
And in this class I get an error on SpringOpaqueTokenIntrospector, writes that it is not defined. Although all the imports completely coincide with the training example.
If I add a dependency that the IDE tells me to
import org.springframework.security.oauth2.server.resource.introspection.SpringOpaqueTokenIntrospector;
, then I get an error
Type mismatch: cannot convert from KeycloakReactiveTokenInstrospector to SpringOpaqueTokenIntrospector
What's the problem here? Is there some kind of dependency missing?
I completely repeated the structure of the project from the training material.
So far, I would like to build a project without errors.

Marcus is right in his comment, your keycloakIntrospector #Bean type should be ReactiveOpaqueTokenIntrospector (and not SpringOpaqueTokenIntrospector as declared in your conf)
Few facts:
SpringReactiveOpaqueTokenIntrospector is a ReactiveOpaqueTokenIntrospector but SpringOpaqueTokenIntrospector isn't
your KeycloakReactiveTokenInstrospector is (implements) a ReactiveOpaqueTokenIntrospector too but is neither a SpringReactiveOpaqueTokenIntrospector, SpringOpaqueTokenIntrospector nor OpaqueTokenIntrospector
Side notes
Introspection VS JWT decoding
Keycloak issues JWTs. JWT decoding is far more efficient than introspection: resource-server needs to fetch public-key only once from authorization-server to validate all incoming JWTs when introspection requires to submit access-token to authorization-server for each and every incoming request.
Also, you might not be able to implement multi-tenant scenarios with introspection: how to figure out by which issuer (Keycloak instance or realm) an opaque token was emitted? => you would have to "try" introspection on each issuer until one responds positively :/
Overriding introspector VS providing an authentication converter
If you switch to spring-security 5.8 or higher, customizing introspection is easier: you don't have to override the all introspector but can just provide a ReactiveOpaqueTokenAuthenticationConverter bean instead:
http.oauth2ResourceServer().opaqueToken().authenticationConverter(
(String introspectedToken, OAuth2AuthenticatedPrincipal authenticatedPrincipal) ->
new BearerTokenAuthentication(...));
This bean is called after introspection was successfuly completed (and token attributes retrieved) but before Authentication is instanciated and put in security-context which allows you to just map authorities from any attribute you like or completely switch the authentication implementation.
Simplifying your resource-server configuration
I host a set of libs to ease OAuth2 resource-server testing and configuration. There are various spring-boot starters depending on introspection or JWT decoding is used into servlet or reactive apps.
According to your case (reactive app with introspection), you should have a look at this sample with BearerTokenAuthentication and this other one with a custom authentication.
Configuration can be as simple as:
#EnableReactiveMethodSecurity
#Configuration
public class SecurityConfig {
}
spring.security.oauth2.resourceserver.opaquetoken.introspection-uri=https://localhost:8443/realms/master/protocol/openid-connect/token/introspect

no listing appears using swagger on jersey 2 with grizzly

I have setup swagger on jersey 2 and grizzly (no web.xml). I am able to access the swagger page however my API resources do not appear.
My main file is seen below
`
package com.beraben.jersey.test;
import com.wordnik.swagger.jaxrs.config.BeanConfig;
import java.net.URI;
import org.glassfish.grizzly.http.server.CLStaticHttpHandler;
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
/**

*/
public class jerseyTestMain {
/**
* #param args the command line arguments
*/
public static final String BASE_URI = "http://localhost:8080/myapp/";
public static HttpServer startServer() {
// create a resource config that scans for JAX-RS resources and providers
// in com.example.rest package
final ResourceConfig rc = new ResourceConfig().packages("com.beraben.jersey.test", "com.wordnik.swagger.jersey.listing");
BeanConfig config = new BeanConfig();
config.setResourcePackage("com.beraben.jersey.test");
config.setVersion("1.0.0");
config.setScan(true);
// create and start a new instance of grizzly http server
// exposing the Jersey application at BASE_URI
return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
}
public static void main(String[] args) throws InterruptedException {
final HttpServer server = startServer();
CLStaticHttpHandler staticHttpHandler = new CLStaticHttpHandler(jerseyTestMain.class.getClassLoader(), "swagger-ui/");
server.getServerConfiguration().addHttpHandler(staticHttpHandler, "/docs");
Object syncObj = new Object();
synchronized (syncObj) {
syncObj.wait();
}
}
}
`
I also have a API setup seen below
package com.beraben.jersey.test;
import com.wordnik.swagger.annotations.Api;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
/**
*
* #author Evan
*/
#Path("myresource")
#Api(value = "/myresource")
public class MyResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String getIt(){
return "Got it!";
}
}
I have no problem using the API it returns correctly.
But for some reason I cant get swagger to show details about the API calls, is there something i need to do more to get it to show details about the existing API in my code?
My static files are copied from the sample project
jersey2-grizzly2-swagger-demo
Also for reference, here is my pom file (not slight difference from the demo project is I don't use dependencyManagment to get jersey-bom instead i reference it directly).

After looking at the google forms, it turns out that standalone version of swagger does not actually work.
I created a separate maven web app and added my jersey project as dependencies. This worked after fiddling around with the swagger version that matched the jersey version I was using.

What's the problem, why doesn't it find JPA entities when I run WebApplicationAware class?

Spring does not find any JPA Entities, so no JPA Meta Model is created, that is why you face the exception.
The cause of this problem may be a wrong persistence-api version on your class path.
You are using
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0.2</version>
</dependency>
but I am pretty shure your spring version uses persistence-api version 2.
Could it be, you are using #Entity annotation from version 1 ?
At runtime spring uses version 2, and this is searching for Entites using #Entity from version 2 only !
Remove the dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.11.1.RELEASE</version>
</dependency>
Instead add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
This will give you all JPA dependencies in the right version.

I solved it by adding 2 annotations
#EnableAutoConfiguration
#EntityScan(basePackages = { "com.wt.rds" })
and my dependency was in gradle
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.0.4.RELEASE'

Unfortunately, most of the springboot guides on JPA integration test often lack a piece of configuration here and there.
So here is an example that hopefully should just work for you.
Point 1.
My local environment is currently setup to use springboot version:
<version.spring.boot>1.5.9.RELEASE</version.spring.boot>
That being said, I am currently setting up my local environment to be able to run integration tests against multiple databases (e.g. postgres, hsql, h2).
Therefore, I start by googling any random toturial that approaches this problem.
The next link is one such example:
https://www.baeldung.com/spring-testing-separate-data-source
The above example is a good starting point. It allows you to scoop up a valid Entity and a Valid repository. The springboot test class itself, on the other hand, leaves a lot ot be desired.
With the above example, you will immediately struggle with the integration test. You will get the usuable problems about the example not giving you the application.class to configure the integration test, and you are left hanging clueless as to what springboot annotations you need to put "where" to make the test to finally run without explosions.
So now I give you a MINIMAL set of 3 classes (Entity + Repository + SpringbootTest) that should hopefully have 100 percent of the configuration you need. This will serve as a basis of any JPA based integration test you will need to do in the future, then you can swap your entities and repositories, and continue testing with the same type of srpingboot configuration.
I start by giving you the IRRELEVANT classes. The stuff that is always the same, the stuff that you want to test, and that has nothing to do with configuration.
I am referring to REPOSITORY + ENTITY.
In eclipse create your java package:
tutorial.www.baeldung.com.tutorial001jpa.separateDS
Dump into this package the following trivial entity and repository classes, that are based on the tutorial reference I gave above.
Tutorial001GenericEntity
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "TUTORIAL_001_GENERIC_ENTITY")
public class Tutorial001GenericEntity {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String value;
public Tutorial001GenericEntity() {
super();
}
public Tutorial001GenericEntity(String value) {
super();
this.value = value;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
// standard constructors, getters, setters
}
Then we go for the second trivial code snippet.
The spring repository boiler plate code.
Tutorial001GenericEntityRepository
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import org.springframework.data.jpa.repository.JpaRepository;
public interface Tutorial001GenericEntityRepository extends JpaRepository<Tutorial001GenericEntity, Long> {
}
At this point your maven project, src/test/java has a total of two classes. The basic stuff.
An entity and a repository, that serve as an example of any integration test you will ever need to do.
So now you go to the only important class in the example, the stuff that always gives a lot of problems, and that is the springboot test class which more then being responsible to test your business logic also has the complex task of CONFIGURING your test.
In this case, this test class has ALL IN ONE the annotations that allow springboot to disocver your entities, repositories, etc...
package tutorial.www.baeldung.com.tutorial001jpa.separateDS;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#ContextConfiguration(classes = {
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class })
#SpringBootTest()
public class Tutorial001GenericEntityIntegrationTest {
#EntityScan(basePackageClasses = { Tutorial001GenericEntity.class })
#EnableJpaRepositories(basePackageClasses = Tutorial001GenericEntity.class)
#EnableAutoConfiguration()
public static class ConfigureJpa {
}
#Autowired
private Tutorial001GenericEntityRepository genericEntityRepository;
#Test
public void givenTutorial001GenericEntityRepository_whenSaveAndRetreiveEntity_thenOK() {
Tutorial001GenericEntity genericEntity = genericEntityRepository.save(new Tutorial001GenericEntity("test"));
Tutorial001GenericEntity foundEntity = genericEntityRepository.findOne(genericEntity.getId());
assertNotNull(foundEntity);
assertEquals(genericEntity.getValue(), foundEntity.getValue());
}
}
The important thing, you see, is that this spring boot test has a class level annotation to provide to the springboot test the configuration context.
What we are doing is dumping one and only one class reference that represents our test configuration.
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class
And then on this little guy, you put all of the additional annotations in the world you need that springboot offers to configure applications.
In this case we have a dedicated annotation to mention entities.
Another to mention repositories.
And another to tell springboot to activate its auto configuration.
This springboot auto configuration annotation then does additional vodoo, like looking at your classpath and seeing that you have in the classpath say:
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>test</scope>
<version>2.3.4</version>
</dependency>
And it will immediately know how to configure an in memory data source for this database.
Behind the scenes, there might be additional configuration that is getting used.
For example, if you create an application.properties file in your src/test/resources that file will be considered.
It is very to see that the appliction.properties is considered by your running test.
If you want to verify this, make sure that in your test setup you do not have, for example, any dependency on the JDBC driver for postgres.
And then put into your application.properties something liek this:
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
This dialect is not compatible with HSQL or H2, so it will immediately make your green passing integration test blow up.
To be honest, I do not know if there is a simpler combo of annotations to properly configure the springboot scanning for an integration test.
As a rule, I would recommend that you try avoiding having hundreds of thousands of configuration classes in your src/test/resources.
Because if at some point you want to toggle all of your integration tests from using applicat-postgres.proeprties to application-hsql.properties, you might find yourself needing to tweak multiple configuration classes instead of just one.
So as rule, per maven component you write, I would try to have the tests that check repositories extend some sort of MyBaseINtegrationTestClass, and in there put this
#ContextConfiguration(classes = {
tutorial.www.baeldung.com.tutorial001jpa.separateDS.Tutorial001GenericEntityIntegrationTest.ConfigureJpa.class })
So that you only need to play with one configuration for testing for the hole project.
IN any case, hopefully the triplet of classes given here helps you.
One finel thing, for maven dependencies for integration testing, here is what I am using:
<!-- Test Dependencies JPA REPOSITORY TESTS -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<scope>test</scope>
</dependency>

<scope>test</scope>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>test</scope>
</dependency>
The reason why i am using hsql and h2 is beacuse I want my integration tests to be able to be tunned to either use application-hsql or application-h2.properties.

MessageBodyWriter not found for media type=application/json with GF4 and Jackson

I got the following error message every time I try to call my REST service
[2016-09-01T16:27:37.782+0200] [Payara 4.1] [SEVERE] [] [org.glassfish.jersey.message.internal.WriterInterceptorExecutor] [tid: _ThreadID=28 _ThreadName=http-listener-1(3)] [timeMillis: 1472740057782] [levelValue: 1000] [[MessageBodyWriter not found for media type=application/json, type=class xxx.JsonClass, genericType=class xxx.JsonClass.]]
Here's the REST service (stripped to the relevant part):

POM.xml (interesting parts)
<!-- DO NOT change the scope for jersey: https://java.net/jira/browse/JERSEY-1941 -->
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.8</version>
<scope>provided</scope>
</dependency>
My setup is:
JDK8/JEE7 (build 1.8.0_51-b16)
Glassfish 4.1 Payara
Maven 3.2.5
This is what I tried so far:
MessageBodyWriter not found for media type=application/json -> Doesn't work because I run into a problem with Glassfish 4 and Weld (https://java.net/jira/browse/JERSEY-1941)
SEVERE: MessageBodyWriter not found for media type=application/json, type=class com.jersey.jaxb.Todo, genericType=class com.jersey.jaxb.Todo -> As seen in the POM.xml above it's already included and does not work
https://java.net/jira/browse/JERSEY-2715 -> Annotation #Produces is already there and doesn't help either
Obtaining "MessageBodyWriter not found for media type=application/json" trying to send JSON object through JAX-RS web service - GENSON with #XmlAttribute had not the desired effect
I tried to keep the JSON object as simple as possible to avoid problems with arrays and complex objects -> No change
I still think it's a dependency problem here. However I'm out of ideas what could be the problem.

Unfortunately my last post was marked as duplicate although the problem and the solution was different. Therefore I'm posting a new question with the two solutions to hopefully help you avoid head banging at the table for several hours.
Preferred solution:
Apparently GF4 ships with MoxyJson which I didn't want to use. To integrate your own dependency - in my case Jackson - you need to disable the MoxyJson with the below code.
#ApplicationPath("/")
public class ApplicationConfig extends Application {
/**
* {#inheritDoc}
*/
#Override
public Map<String, Object> getProperties() {
final Map<String, Object> properties = new HashMap<String, Object>();
properties.put("jersey.config.server.disableMoxyJson", true);
return properties;
}
}
Then add your own dependencies, e.g. in my case only those two because the others are referenced by another lib I use.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.6.2</version>
</dependency>
Finally I made the mistake of not setting a value to the #JsonProperty annotations which will cause a No MessageBodyWriter found exception. To avoid that use the following ony relevant getters of your class.
#JsonProperty("randomName")
public String getRandomName(){
...
}
Alternative:
Worse than above you'll need to disable MoxyJson, register each service individually, and fix a Bug when using ResourceConfig of GF.
#ApplicationPath("/")
public class ApplicationConfig extends ResourceConfig {
/**
* The default constructor.
*/
public ApplicationConfig() {
// Disable Moxy and use Jackson
this.property(ServerProperties.MOXY_JSON_FEATURE_DISABLE, true);
// Register own provider classes
this.register(Fully.Qualified.Path.To.Your.Service.class);
// Register Jackson provider
// Workaround for GF4.1 bug for details: https://java.net/jira/browse/GLASSFISH-21141
final ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JaxbAnnotationModule());
this.register(new JacksonJaxbJsonProvider(mapper, JacksonJaxbJsonProvider.DEFAULT_ANNOTATIONS));
}
}
You'll need an additional dependency for the ResourceConfig class.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.6.2</version>
</dependency>
<dependency>
<groupId>org.glassfish.main.extras</groupId>
<artifactId>glassfish-embedded-all</artifactId>
<version>4.1.1</version>
<scope>provided</scope>
</dependency>
Finally the same as above - be aware to use #JsonProperty with a set value.

Resteasy and CorsFilter implementation

I'm trying implement the CorsFilter from Resteasy (3.0.16). My currently environment is: java 7 and jboss 7.1. I've tried several ways, but no one works.
Actually CorsFeature.java (#Provider) it's never instantiate, and i can't get the correct headers. I also tried override methods in Application class (with web.xml and so on) but CorsFeature never intercepts anything.
Here is my code, if anyone can help me:

return true;
}
}
