我尝试转换包含非常简单的REST服务的教程（应该部署到karaf中）。

PersonService界面非常简单：

@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;
    }

}

这就是这个意图： 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);
    }

}

测试看起来像这样： 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测试产生了这个警告，但这意味着我没有得到结果：

2016-08-16 11：02：52,306 [tp1293680734-19]警告 WebApplicationExceptionMapper - javax.ws.rs.ClientErrorException： HTTP 415不支持的媒体类型 org.apache.cxf.jaxrs.utils.SpecExceptions.toHttpException（SpecExceptions.java:117）在 org.apache.cxf.jaxrs.utils.ExceptionUtils.toHttpException（ExceptionUtils.java:162）在 org.apache.cxf.jaxrs.utils.JAXRSUtils.findTargetMethod（JAXRSUtils.java:530）在 org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.processRequest（JAXRSInInterceptor.java:177）在 org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.handleMessage（JAXRSInInterceptor.java:77）在 org.apache.cxf.phase.PhaseInterceptorChain.doIntercept（PhaseInterceptorChain.java:308）在 org.apache.cxf.transport.ChainInitiationObserver.onMessage（ChainInitiationObserver.java:121）在 org.apache.cxf.transport.http.AbstractHTTPDestination.invoke（AbstractHTTPDestination.java:253）在 org.apache.cxf.transport.http_jetty.JettyHTTPDestination.doService（JettyHTTPDestination.java:234）在 org.apache.cxf.transport.http_jetty.JettyHTTPHandler.handle（JettyHTTPHandler.java:70）在 org.eclipse.jetty.server.handler.ContextHandler.doHandle（ContextHandler.java:1129）在 org.eclipse.jetty.server.handler.ContextHandler.doScope（ContextHandler.java:1065）在 org.eclipse.jetty.server.handler.ScopedHandler.handle（ScopedHandler.java:141）在 org.eclipse.jetty.server.handler.ContextHandlerCollection.handle（ContextHandlerCollection.java:215）在 org.eclipse.jetty.server.handler.HandlerWrapper.handle（HandlerWrapper.java:97）在org.eclipse.jetty.server.Server.handle（Server.java:499）at org.eclipse.jetty.server.HttpChannel.handle（HttpChannel.java:310）at at org.eclipse.jetty.server.HttpConnection.onFillable（HttpConnection.java:257）在 org.eclipse.jetty.io.AbstractConnection $ 2.run（AbstractConnection.java:540）在 org.eclipse.jetty.util.thread.QueuedThreadPool.runJob（QueuedThreadPool.java:635）在 org.eclipse.jetty.util.thread.QueuedThreadPool $ 3.run（QueuedThreadPool.java:555）在java.lang.Thread.run（Thread.java:745）

所以测试失败了。

testInterface测试产生此错误：

我能够将服务部署到karaf并进行交互。但测试没有成功。如果可能的话，我想避免像杰克逊这样的外部框架。

谢谢！

您的服务正在接受任何MediaType，因为您尚未为@Consumes设置默认值（请参阅documentation）。建议将content-type设置为accept

@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，但我认为您需要在<jax-rs_server>

中定义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>
