How to connect from STS(spring tool suite) to database(oracle)

How to connect from STS(spring tool suite) to database(oracle) - java

I am new at spring. I am trying to build my first web service, and I would like to connect to a database, get data, and return it as a JSON.
I use the spring example https://spring.io/guides/gs/rest-service and I change it a bit, so I can get a war file.
My server that war file will deploy is Wildfly 8.2.0.
I want to connect to oracle 11g database and run SQL queries. Can you help me?
My code is posted below.
My project format in eclipse
Application.java:
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Greeting.java:
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
GreetingController.java:
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
#RequestMapping(value="/greeting",method=RequestMethod.GET)
public List<Greeting> greeting(#RequestParam(value="name", defaultValue="World") String name,
#RequestParam(value="content", defaultValue="World") String content,HttpServletResponse response) {
List<Greeting> list_greet = new ArrayList<Greeting>();
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, content)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
list_greet.add(new Greeting(counter.incrementAndGet(),
String.format(template, name)));
//to have webservice work,beacause cors cut it out.
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");

You can use several different ways to archive your objective, for example:
Follow this official doc and use Spring with jpa directly
This one just adapted to spring-boot in combination with official spring jpa example

Endpoint specifications ("paths" field) not getting generated in the Swagger API specification file generated by swagger-maven-plugin

I have a simple swagger annotated API (a GET and a POST method). I'm trying to generate the Swagger API specification file using the swagger-maven-plugin. The Swagger API specifications file is getting created but the problem is that it only has the API meta data in it and no info about the endpoints is getting generated i.e. the "paths" field is not getting generated.

}
}
As you can notice there is no information about the endpoints in the above specification. Please help.
Thanks in advance!

I was facing the same issue, try using plugin version 3.1.7 instead of 3.1.1
and the also change the locations tag, try
<locations>
<location>com.example.restapi.DriverController</location>
</locations>
It worked for me after making these changes.

Basic Spring based WSSecurity client gets a null response

I've been following this tutorial to learn how to develop a basic spring client and server application using wssecurity (certificates).
The demo works beautifully, but i need to deploy my application on a wildfly server, so i had to change the example a bit in order to avoid the embedded tomcat, the changes are as follows:

GetBeerResponse beerResponse = new GetBeerResponse();
Beer beer = new Beer();
beer.setId(request.getId());
beer.setName("Beer name");
beerResponse.setBeer(beer);
return beerResponse;
}
}
I deployed the server application on my wildfly and i tried to call it using the same client application used in the tutorial. The service seems to answer correctly, the beerResponse object is correctly istantiated, but, as soon as the object is being sent back to the the client, i see it's NULL.
What am i missing?
Thanks in advance

Oh well, next time i'll read better. At the same link of my first post, a guy asked the same question in the comments, here is the solution: add a callBackHandler to the client configuration, and modify the securityInterceptor to use this handler.
SoapClientConfig.java

import org.springframework.ws.client.support.interceptor.ClientInterceptor;
import org.springframework.ws.soap.security.wss4j2.Wss4jSecurityInterceptor;
import org.springframework.ws.soap.security.wss4j2.callback.KeyStoreCallbackHandler;
import org.springframework.ws.soap.security.wss4j2.support.CryptoFactoryBean;
import java.io.IOException;
#Configuration
public class SoapClientConfig {
#Bean
public Wss4jSecurityInterceptor securityInterceptor() throws Exception {
Wss4jSecurityInterceptor securityInterceptor = new Wss4jSecurityInterceptor();
// set security actions
securityInterceptor.setSecurementActions("Timestamp Signature Encrypt");
// sign the request
securityInterceptor.setSecurementUsername("client");
securityInterceptor.setSecurementPassword("changeit");
securityInterceptor.setSecurementSignatureCrypto(getCryptoFactoryBean().getObject());
// encrypt the request
securityInterceptor.setSecurementEncryptionUser("server-public");
securityInterceptor.setSecurementEncryptionCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setSecurementEncryptionParts("{Content}{http://memorynotfound.com/beer}getBeerRequest");
// sign the response
securityInterceptor.setValidationActions("Signature Encrypt");
securityInterceptor.setValidationSignatureCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setValidationDecryptionCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setValidationCallbackHandler(securityCallbackHandler());
return securityInterceptor;
}
#Bean
public CryptoFactoryBean getCryptoFactoryBean() throws IOException {
CryptoFactoryBean cryptoFactoryBean = new CryptoFactoryBean();
cryptoFactoryBean.setKeyStorePassword("changeit");
cryptoFactoryBean.setKeyStoreLocation(new ClassPathResource("client.jks"));
return cryptoFactoryBean;
}
#Bean
public Jaxb2Marshaller getMarshaller(){
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath("com.memorynotfound.beer");
return marshaller;
}
#Bean
public BeerClient getBeerClient() throws Exception {
BeerClient beerClient = new BeerClient();
beerClient.setMarshaller(getMarshaller());
beerClient.setUnmarshaller(getMarshaller());
beerClient.setDefaultUri("http://localhost:8080/ws/beers");
ClientInterceptor[] interceptors = new ClientInterceptor[]{securityInterceptor()};
beerClient.setInterceptors(interceptors);

Programmatic Control over entry-time-to-live in Gemfire Region with ClientRegionShortcut.PROXY

Is it possible to have a ClientCache with ClientRegionShortcut.PROXY along with programmatic control over entry TTL settings (i.e. entries present in the server)? I see the entry expiration ttl settings working fine with ClientRegionShortcut.CACHING_PROXY_HEAP_LRU. In this case I can see the entries getting invalidated in server after the configured timeout in seconds, but that is not the case for ClientRegionShortcut.PROXY settingsIs it NOT possible to dynamically control the entry-ttl settings for a ClientCache? Below code/config works with ClientRegionShortcut.CACHING_PROXY_HEAP_LRU and NOT with ClientRegionShortcut.PROXY.
The Gemfire version is : 9.0.x

How to run this with out spring boot

I am new to spring and maven, i do have this app which is referring from, https://spring.io/guides/gs/rest-service/
I am using spring + maven.
I need to get the output into a simple html via tomcat, currently it is using embedded Apache Tomcat 7.
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
package hello;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
#RequestMapping("/greeting")
public Greeting greeting(#RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
}
This is the main which uses spring boot, to run in embedded Apache.
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Can someone help me with this! What i need is simple web service without embedded tomcat. just need normal tomcat deploying.
pom.xml is as bellow.

Perfect Solution and code to your Question
SpringBoot contains Embedded Tomcat, Hence there is no special configuration required in your POM.xml
Your POM.xml should like this below code. I have used bootsample as an artifact and hence rest are all same.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
Your Controller, Before careful you have use #ResponseBody annotation, else you will get circularpath ViewResolver Exception, because SpringBoot sets default viewResolver. This #ResponseBody annotation will skip your ViewResolver problems.
/**

import java.util.concurrent.atomic.AtomicLong;

return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SimpleController.class, args);
}
}
Please use the Maven Goals as indicated in below figure.
Your maven goals should be mvn clean package spring-boot:run -e
Once you execute this, your embedded tomcat will run and you can find your successful output.
Successful Log
Additionally you can refer this link Spring-boot reference documentation. for your WAR/JAR creation questions.

Add This to your POM
<packaging>war</packaging>
and do mvn install or mvn package
You will see in your target folder the artifact ending with xxx.war.original. That one can be deployed straight into Tomcat.
edit:- Update as per comments below. Following changes needs to be made as well.
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}

Problems with Postgresql with Spring Boot on Heroku

I decided to try out Spring Boot on Heroku and everything works perfectly...well, apart from the database!
I tried many different things to make it work, followed a lot of different approaches I found online and also from questions on StackOverflow, but nothing seems to work for me.
I'm going to post only the bare minimum of the app I'm trying to deploy.
The below is desployed fine, but when I'm trying to POST something I get the following as response:
{"timestamp":1413600470146,"error":"Unsupported Media Type","status":415,"message":"Unsupported Media Type"}
And when I'm trying to GET, I get the following exception in the Heroku logs:
nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet] with root cause
org.postgresql.util.PSQLException: ERROR: relation "exampleEntity" does not exist
Position: 109
at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2103)
at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1836)
at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:257)
at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:512)

at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:273)
at org.apache.commons.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:96)
....
So, I have the following pom.xml:

Then my Main class is:
package com.example;
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.servlet.ServletProperties;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import com.example.config.JerseyConfig;
#EnableAutoConfiguration
#ComponentScan
#EnableJpaRepositories
public class Main {
#Bean
public ServletRegistrationBean jerseyServlet() {
ServletRegistrationBean registration = new ServletRegistrationBean(new ServletContainer(), "/rest/*");
// our rest resources will be available in the path /rest/*
registration.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS, JerseyConfig.class.getName());
return registration;
}
public static void main(String[] args) {
new SpringApplicationBuilder(Main.class).showBanner(false).run(args);
}
}
I also have a JerseyConfig (for Jersey configuration):
package com.example.config;
import org.glassfish.jersey.filter.LoggingFilter;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.spring.scope.RequestContextFilter;
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
register(RequestContextFilter.class);
packages("com.example");
register(LoggingFilter.class);
}
}
And a BasicDataSource for the database:
package com.example.config;
import java.net.URI;
import java.net.URISyntaxException;
import javax.sql.DataSource;
import org.apache.commons.dbcp.BasicDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
#Configuration
public class SimpleDbConfig {
#Bean
public DataSource dataSource() throws URISyntaxException {
URI dbUri;
try {
String username = "username";
String password = "password";
String url = "jdbc:postgresql://localhost/dbname";
String dbProperty = System.getProperty("database.url");
if(dbProperty != null) {
dbUri = new URI(dbProperty);
username = dbUri.getUserInfo().split(":")[0];
password = dbUri.getUserInfo().split(":")[1];
url = "jdbc:postgresql://" + dbUri.getHost() + dbUri.getPath();
}
BasicDataSource basicDataSource = new BasicDataSource();
basicDataSource.setUrl(url);
basicDataSource.setUsername(username);
basicDataSource.setPassword(password);
return basicDataSource;
} catch (URISyntaxException e) {
//Deal with errors here.
throw e;
}
}
}
Finally, I have my REST resource:
package com.example.resource;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.example.service.ExampleService;
import com.example.transport.ExampleEntity;
#Path("/entities")
#Component
public class ExampleResource {
private ExampleService exampleService;
#Autowired
public ExampleResource(ExampleService exampleService) {
this.exampleService = exampleService;
}
#POST
#Path("/new")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public ExampleEntity createNewEntity(ExampleEntity entity) {
return exampleService.createNewEntity(entity);
}
#GET
#Path("/{id}")
#Produces(MediaType.APPLICATION_JSON)
public ExampleEntity getExampleDetails(#PathParam("id") Long id) {
return exampleService.findEntity(id);
}
}
A service class:
package com.example.service;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.example.repositories.ExampleRepository;
import com.example.transport.ExampleEntity;
#Service
public class ExampleService {
private ExampleRepository repo;
#Autowired
public ExampleService(ExampleRepository repo) {
this.repo = repo;
}
#Transactional
public ExampleEntity createNewEntity(ExampleEntity entity) {
ExampleEntity savedEntity = repo.save(entity);
return savedEntity;
}
#Transactional
public ExampleEntity findEntity(Long id) {
return repo.findOne(id);
}
}
The entity:
package com.example.transport;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
#Entity
public class ExampleEntity {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
private String name;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
And finally the repo interface:
package com.example.repositories;
import org.springframework.data.repository.CrudRepository;
import com.example.transport.ExampleEntity;
public interface MeetingRepository extends CrudRepository<ExampleEntity, Long> {
}
Any help is much appreciated!
Edit:
The Procfile I'm using is the following:
web: java -Dserver.port=$PORT -Ddatabase.url=$DATABASE_URL $JAVA_OPTS -jar target/project-name-0.0.1-SNAPSHOT.jar

It seems you have not created the table exampleEntity yet. I can see you are using postgreSQL, so please use heroku config | grep HEROKU_POSTGRESQL to check if you have one enabled in heroku (also its name and url). If not, enable it in your heroku account manager, it's a free plugin.
Use heroku pg:promote HEROKU_POSTGRESQL_<color of your db> to promote it to the main one. You will get some output like:
Promoting HEROKU_POSTGRESQL_BROWN_URL (DATABASE_URL) to DATABASE_URL... done
Now you should use DATABASE_URL environment variable to connect to your db. Heroku will provide it for you. (Also please post your Procfile too).
Using the url connect to your database and add the required table with a schema that maches your ExampleEntity class.
Side notes
Connecting to heroku db:
https://devcenter.heroku.com/articles/connecting-to-heroku-postgres-databases-from-outside-of-heroku
If you didn't understand some heroku stuff I wrote, their documentation is really well written:
https://devcenter.heroku.com/categories/heroku-architecture
https://devcenter.heroku.com/articles/heroku-postgresql
If I understood you all wrong and you're running your app on localhost and didn't deploy it to heroku yet, then just add the table to your local db instance.

Example I use with automatic table generation
Apart from DATABASE_URL, which is always there, Heroku creates 3 environment variables at Runtime. They are:
JDBC_DATABASE_URL
JDBC_DATABASE_USERNAME
JDBC_DATABASE_PASSWORD
As you may be aware, Spring Boot will automatically configure your database if it finds spring.datasource.* properties in your application.properties file. Here is an example of my application.properties
spring.datasource.url=${JDBC_DATABASE_URL}
spring.datasource.username=${JDBC_DATABASE_USERNAME}
spring.datasource.password=${JDBC_DATABASE_PASSWORD}
spring.jpa.show-sql=false
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
Hibernate / Postgres Dependencies
In my case I'm using Hibernate (bundled in spring-boot-starter-jpa with PostgreSQL, so I needed the right dependencies in my build.gradle:
dependencies {
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile('org.postgresql:postgresql:9.4.1212')
}
