PersonService 接口超级简单：
@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);
}
模型看起来像这样：
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;
}
}
这是实现：
包裹 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());

}
}

我能够将服务部署到 karaf 中并进行交互。但是测试没有成功。如果可能的话，我想避免像 jackson 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）。建议将内容类型设置为 accept
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public interface PersonService {
您需要在客户端设置内容类型
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" />
