Return XML response Rest API with Spring

I am trying to response with XML to a given call to the API.
Right now it works with JSON, I can send JSON or XML and return JSON.
But I cannot do the same with XML.
From now what I have is this:
RestVoterController class:
#RequestMapping("/rest")
#RestController
public class RESTVoterController {
#Autowired
private VoterService voterService;
#RequestMapping(value = {"/user.json","/user"},
method = RequestMethod.POST,
consumes = {"application/json","application/xml"},
produces = {"application/json"})
#Transactional(readOnly = true)
public Voter getVoterInfoJSON(#RequestBody VoterRequestGet voterRequestGet) {
return this.voterService.findByEmailAndPassword(voterRequestGet.getLogin(), voterRequestGet.getPassword());
}
#RequestMapping(value = "/user.xml",
method = RequestMethod.POST,
consumes = {"application/xml","application/json"},
produces = "application/xml")
#Transactional(readOnly = true)
public Voter getVoterInfoXML(#RequestBody VoterRequestGet voterRequestGet) {
return this.voterService.findByEmailAndPassword(voterRequestGet.getLogin(), voterRequestGet.getPassword());
}
#RequestMapping(value = "/changepassword",
method = RequestMethod.POST,
headers = "Accept=application/json",
produces = "application/json")
#Transactional(readOnly = true)
public void changePassword(#RequestBody VoterRequestChangePassword voterRequestChangePassword) {
this.voterService.changePassword(voterRequestChangePassword.getLogin(), voterRequestChangePassword.getOldPassword(), voterRequestChangePassword.getNewPassword());
}
}
VoterRequestGet class:
#XmlRootElement(name = "user")
#XmlAccessorType(XmlAccessType.FIELD)
public class VoterRequestGet {
#XmlElement
private String login;
#XmlElement
private String password;
public VoterRequestGet()
{
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

I tested your code and it works for me. Please look:
First I create mock for voterService.
package com.example;
import org.springframework.stereotype.Service;
#Service
public class VoterService {
public Voter findByEmailAndPassword(String login, String password) {
Voter voter = new Voter();
voter.setLogin(login);
voter.setPassword(password);
return voter;
}
}
Then I have to slightly modify your controller (remove Transaction annotation because I have no data source in my service mock).
package com.example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RequestMapping("/rest")
#RestController
public class RESTVoterController {
#Autowired
private VoterService voterService;
#RequestMapping(value = {"/user.json","/user"},
method = RequestMethod.POST,
consumes = {"application/json","application/xml"},
produces = {"application/json"})
public Voter getVoterInfoJSON(#RequestBody VoterRequestGet voterRequestGet) {
return this.voterService.findByEmailAndPassword(voterRequestGet.getLogin(), voterRequestGet.getPassword());
}
#RequestMapping(value = "/user.xml",
method = RequestMethod.POST,
consumes = {"application/xml","application/json"},
produces = "application/xml")
public Voter getVoterInfoXML(#RequestBody VoterRequestGet voterRequestGet) {
return this.voterService.findByEmailAndPassword(voterRequestGet.getLogin(), voterRequestGet.getPassword());
}
}
Also I have to create mock for Voter because you don't share it.
package com.example;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement(name = "voter")
#XmlAccessorType(XmlAccessType.FIELD)
public class Voter {
#XmlElement
private String login;
#XmlElement
private String password;
public Voter() {
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#Override
public String toString() {
return "Voter [login=" + login + ", password=" + password + "]";
}
}
And finally integration test.
package com.example;
import javax.annotation.Resource;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.web.ServerProperties;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.boot.test.WebIntegrationTest;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.web.client.RestTemplate;
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = TestApplication.class)
#WebIntegrationTest("server.port:0")
public class RESTVoterControllerTest {
private ServerProperties serverProperties;
private RestTemplate restTemplate = new RestTemplate();
#Resource
public void setServerProperties(ServerProperties serverProperties) {
this.serverProperties = serverProperties;
}
#Value("${local.server.port}")
private int serverPort;
private String serverUri;
#Before
public void setUp() throws Exception {
String contextPath = serverProperties.getContextPath();
serverUri = "http://localhost:" + serverPort + (contextPath == null ? "/" : contextPath);
}
#After
public void tearDown() throws Exception {
}
#Test
public void testCreate() throws Exception {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_XML);
VoterRequestGet voterRequest = new VoterRequestGet();
voterRequest.setLogin("email");
voterRequest.setPassword("secret");
HttpEntity<VoterRequestGet> request = new HttpEntity<>(voterRequest, headers);
System.out.println(restTemplate.postForEntity(
serverUri + "/rest/user.json", request, String.class).getBody());
System.out.println(restTemplate.postForEntity(
serverUri + "/rest/user.xml", request, String.class).getBody());
}
}
The result could be find in a output of the test and should contain two lines.
{"login":"email","password":"secret"}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><voter><login>email</login><password>secret</password></voter>

You need an XML mapping library like jackson, so adding this to your pom.xml will fix your problem:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>

produces = { MediaType.APPLICATION_JSON_VALUE}
is the solution to me

Jersey Client - Variable types are ignored

I am using the Jersey Client of Sun Version 1.19...
When I send a put request with JSON (but every other request type probably as well) it serializes Number-typed variables with quotes, instead of as plain numbers.
Example:
User.java
package de.topazmedia.component.api.rest.client.ressource;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
#XmlAccessorType(XmlAccessType.PUBLIC_MEMBER)
public class User {
Long id;
String username;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return id;
}
public void setUsername(Long id) {
this.id = id;
}
}
Test.java
import javax.ws.rs.core.MediaType;
import org.json.JSONObject;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.WebResource.Builder;
public class Test {
public static void main(String[] args) {
User user = new User();
user.setId(1);
user.setUsername("Test");
ClientResponse response = null;
WebResource webResource = client.resource(http://192.168.23.56:9181/v1/users/" + user.getId());
Builder builder = webResource.header("Accept-Language", "de").type(MediaType.APPLICATION_JSON_TYPE).accept(MediaType.APPLICATION_JSON_TYPE);
response = builder.put(ClientResponse.class, user);
}
}
The "User JSON" I put as entity in the request is now translated to
{"id":"1","username":"Test"}
BUT it should be without the apostrphes at the id like this:
{"id":1,"username":"Test"}
What is wrong?

The solution of the problem ist quite simple.
Just define a POJO-Mapping in the ClientConfig when instantiating the Client Object:
ClientConfig cc = new DefaultClientConfig();
cc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
client = Client.create(cc);

documentTypeId is primarykey for cd_documentTypes table, this primarykey is used in cd_accounts table as a foreignkey.
If the table having foreignkey relation we must mention the #DynamoDBRangeKey annotation above documentTypeId attribute in Account class. Problem is solved after declared the #DynamoDBRangeKey on top of the attribute documentTypeId.
#DynamoDBRangeKey
private String documentTypeId;
If we want to save or update or delete records in amazon dynamodb using java we must mention the
annotation #DynamoDBHashKey on top of the primarykey column.
#DynamoDBAutoGeneratedKey
#DynamoDBHashKey
private String accountId;
Below is the image shown for foreignkey relation exists in cd_accounts table.
Note:Range key attribute field is displayed if the table is mapping to another table primarykey in amaozong dynamodb.

When the update is being called bamm No Session. Why is this happening? GetAll succeeds nice and smooth but that's all to it. Everything else returns in No Session error in my logs.

replace your static block by a before() method, and add the session creation at the end of it :
#Before
public void before() {
Configuration configuration = new Configuration();
configuration = configuration.configure();
StandardServiceRegistryBuilder registryBuilder = new StandardServiceRegistryBuilder();
registryBuilder = registryBuilder.applySettings(configuration.getProperties());
StandardServiceRegistry registry = registryBuilder.build();
sessionFactory = configuration.buildSessionFactory(registry);
session = sessionFactory.openSession();
}
and an after() method :
#After
public void after {
session.close();
sessionFactory.close();
}
And of course, remove all open/close session in each test.

Implementing basic REST API - ServletException

I'm trying to run a sample basic REST API on Eclipse but have been getting ServletException.
Here is the code:
Employee.java

this.name = name;
this.department = department;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDepartment() {

Any help on what I'm possibly doing wrong?

I see you followed a tutorial. I can't find a Jersey version in it, but based on the date of the article, I don't think they use Jersey 2.x. If you do use the latest, try your project with Jersey 1.x. I got it working with 1.11.1 which is bundled with GlassFish 3.1.2.2.

You need to add "/" near
#GET
#Produces(MediaType.TEXT_PLAIN)
#Path("/employeelist")
public String getEmployeesInPlainFormat(){
and
#GET
#Produces(MediaType.TEXT_XML)
#Path("/employeelist")
public String getEmployeesInXmlFormat(){
EmployeeManager should be interface and implementation part should be separate one try like that.
Annotations are present in interface and implementation should be bean
like this
public interface EmployeeManager{
//declarations with annotations
}
public class EmployeeManagerImpl implements EmployeeManager{
// Implementation of methods
}
Use like that it will works

Try this :
package net.javabeat.articles.spring.rest.simple;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("/employee-manager")
public class EmployeeManager {
private static Set<Employee> employees;
#GET
#Produces(MediaType.TEXT_XML)
#Path("/employeelist")
public String getEmployeesInXmlFormat(){
StringBuilder xmlResult = new StringBuilder();
xmlResult.append("<employees>");
Iterator<Employee> iterator = employees.iterator();
while (iterator.hasNext()){
Employee employee = iterator.next();
String employeeAsXml = employee.toXmlString();
xmlResult.append(employeeAsXml);
}
xmlResult.append("</employees>");
return xmlResult.toString();
}
#GET
#Produces(MediaType.TEXT_PLAIN)
#Path("/employeelist")
public String getEmployeesInPlainFormat(){
StringBuilder plainResult = new StringBuilder();
plainResult.append("[employees]");
Iterator<Employee> iterator = employees.iterator();
while (iterator.hasNext()){
Employee employee = iterator.next();
String employeeAsXml = employee.toXmlString();
plainResult.append(employeeAsXml);
}
plainResult.append("[employees]");
return plainResult.toString();
}
static{
employees = new HashSet<Employee>();
employees.add(new Employee("1", "David", "IT"));
employees.add(new Employee("2", "John", "SALES"));
}
}
And then deploy it and you can use any rest client like Advanced REST Client in Google Chrome or REST Client extensioon in Firefox to test the service.
