将CXF REST服务从XML移植到JSON响应
[英]Porting CXF REST Service from XML to JSON response
问题描述
我尝试转换一个包含非常简单的REST服务（应部署到karaf中）的教程。

PersonService接口非常简单：
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public interface PersonService {
@GET
@Path("/")
public Person[] getAll();
@GET
@Path("/{id}")
public Person getPerson(@PathParam("id") String id);
@PUT
@Path("/{id}")
public void updatePerson(@PathParam("id") String id, Person person);
@POST
@Path("/")
public void addPerson(Person person);
}
该模型如下所示：
package net.lr.tutorial.karaf.cxf.personrest.model;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Person {
String id;
String name;
String url;
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 getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
}
这就是实现：package net.lr.tutorial.karaf.cxf.personrest.impl;
import java.util.HashMap;
import java.util.Map;
import net.lr.tutorial.karaf.cxf.personrest.model.Person;
import net.lr.tutorial.karaf.cxf.personrest.model.PersonService;
public class PersonServiceImpl implements PersonService {
Map<String, Person> personMap;
public PersonServiceImpl() {
personMap = new HashMap<String, Person>();
Person person = createExamplePerson();
personMap.put("1", person);
}
private Person createExamplePerson() {
Person person = new Person();
person.setId("1");
person.setName("Ruediger");
return person;
}
public Person[] getAll() {
return personMap.values().toArray(new Person[]{});
}
public Person getPerson(String id) {
return personMap.get(id);
}
public void updatePerson(String id, Person person) {
person.setId(id);
System.out.println("Update request received for " + person.getId() + " name:" + person.getName());
personMap.put(id, person);
}
public void addPerson(Person person) {
System.out.println("Add request received for " + person.getId() + " name:" + person.getName());
personMap.put(person.getId(), person);
}
}
测试如下所示：package net.lr.tutorial.karaf.cxf.personservice.impl;
import java.io.InputStream;
import javax.ws.rs.core.Response;
import net.lr.tutorial.karaf.cxf.personrest.impl.PersonServiceImpl;
import net.lr.tutorial.karaf.cxf.personrest.model.Person;
import net.lr.tutorial.karaf.cxf.personrest.model.PersonService;
import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.apache.cxf.jaxrs.client.JAXRSClientFactory;
import org.apache.cxf.jaxrs.client.WebClient;
import org.junit.AfterClass;
import org.junit.Assert;
import org.junit.BeforeClass;
import org.junit.Test;
public class PersonServiceRestTest {
private static final String PERSONSERVICE_TESTURL = "http://localhost:8282/person";
private static Server server;
@BeforeClass
public static void startServer() {
PersonService personService = new PersonServiceImpl();;
JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
factory.setAddress(PERSONSERVICE_TESTURL);
factory.setServiceBean(personService);
server = factory.create();
server.start();
}
@Test
public void testInterface() {
PersonService personService = JAXRSClientFactory.create(PERSONSERVICE_TESTURL, PersonService.class);
Person person = new Person();
person.setId("1002");
person.setName("Christian Schneider");
personService.updatePerson("1002", person);
Person person2 = personService.getPerson("1002");
assertCorrectPerson(person2);
}
@Test
public void testWebClient() {
WebClient client = WebClient.create(PERSONSERVICE_TESTURL + "/1001");
putPerson(client);
Person person = client.get(Person.class);
assertCorrectPerson(person);
}
private void putPerson(WebClient client) {
InputStream is = this.getClass().getResourceAsStream("/person1.json");
Response resp = client.put(is);
System.out.println(resp);
}
@AfterClass
public static void stopServer() {
server.stop();
}
private void assertCorrectPerson(Person person) {
Assert.assertNotNull(person);
Assert.assertEquals("Christian Schneider", person.getName());
}
}
testWebClient测试产生此警告，但这意味着我没有得到结果：
2016-08-16 11：02：52,306 [tp1293680734-19] WARN WebApplicationExceptionMapper-javax.ws.rs.ClientErrorException：HTTP 415 org.apache.cxf.jaxrs.utils.SpecExceptions.toHttpException（SpecExceptions.java： 117），位于org.apache.cxf.jaxrs.utils.ExceptionUtils.toHttpException（ExceptionUtils.java:162），位于org.apache.cxf.jaxrs.utils.JAXRSUtils.findTargetMethod（JAXRSUtils.java:530），位于org.apache.cxff org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.handleMessage（JAXRSInInterceptor.java:77）处的.jaxrs.interceptor.JAXRSInInterceptor.processRequest（JAXRSInInterceptor.java:177），位于org.apache.cxf.phase.PhaseInterceptorChain。 .java：308），位于org.apache.cxf.transport.ChainInitiationObserver.onMessage（ChainInitiationObserver.java：121），位于org.apache.cxf.transport.http.AbstractHTTPDestination.invoke（AbstractHTTPDestination.java:253）。 org.apache.cxf.trans上的cxf.transport.http_jetty.JettyHTTPDestination.doService（JettyHTTPDestination.java:234） 位于org.eclipse.jetty.server.handler.ContextHandler.doHandle（ContextHandler.java:1129）的port.http_jetty.JettyHTTPHandler.handle（JettyHTTPHandler.java:70）在org.eclipse.jetty.server.handler.ContextHandler.doScope（ org.eclipse.jetty.server.handler.ScopedHandler.handle（ContextdHandler.java:141）位于org.eclipse.jetty.server.handler.ContextHandlerCollection.handle（ContextHandlerCollection.java:215） org.eclipse.jetty.server.Server.handle（Server.java:499）上的.eclipse.jetty.server.handler.HandlerWrapper.handle（HandlerWrapper.java:97）org.eclipse.jetty.server.HttpChannel.handle上的.eclipse.jetty.server.handler.HandlerWrapper.handle（HandlerWrapper.java:97） （HttpChannel.java:310）在org.eclipse.jetty.server.HttpConnection.onFillable（HttpConnection.java:257）在org.eclipse.jetty.io.AbstractConnection $ 2.run（AbstractConnection.java:540）在org.eclipse org.eclipse.jetty.util.thread.QueuedThreadPool $ 3.run（QueuedThreadPool.java:555）的.jetty.util.thread.QueuedThreadPool.runJob（QueuedThreadPool.java:635）在java.lang.Thread.run（Thread。 java：745）
因此测试失败。
testInterface测试产生此错误：

我能够将服务部署到karaf中并进行交互。 但是测试无法解决。 如果可能，我想避免使用像jackson这样的外部框架。
谢谢！

您的服务接受任何MediaType，因为您尚未为@Consumes设置默认值（请参阅文档 ）。 建议将内容类型设置为接受
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public interface PersonService {
您需要在客户端中设置内容类型
client.type( MediaType.APPLICATION_JSON);
我不确定，但是我认为您需要在<jax-rs_server>定义JSON提供程序
<bean id="jackson" class="org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider" />
<jaxrs:server address="/person" id="personService">
<jaxrs:serviceBeans>
<ref component-id="personServiceImpl" />
</jaxrs:serviceBeans>
<jaxrs:features>
<cxf:logging />
</jaxrs:features>
<jaxrs:providers>
<ref bean="jackson" />
</jaxrs:providers>
</jaxrs:server>
