在 REST/JAX-RS 中发布数据时总是收到 400 - 错误请求

Question

Person.java人.java

@XmlRootElement
public class Person {
    
    private int id;
    private String fname;
    private String lname;

    // getter and setter
}

REST POST service REST POST 服务

@POST    
@Consumes({MediaType.APPLICATION_JSON}) 
public void createPerson(JAXBElement<Person> person) {
      Person p = person.getValue();
      System.out.println("========= Person ===========");
      System.out.println(p.getFname() + " " + p.getLname());
      System.out.println("========= Person ===========");
}

OR this one或者这个

@POST    
@Consumes({MediaType.APPLICATION_JSON}) 
public void createPerson(Person person) {          
      System.out.println("========= Person ===========");
      System.out.println(person.getFname() + " " + person.getLname());
      System.out.println("========= Person ===========");
}

Test Client: Always return 400 - Bad request.测试客户端：始终返回 400 - 错误请求。

ClientConfig config = new DefaultClientConfig();
 Client client = Client.create(config);
 WebResource service = client.resource("http://localhost:8084/rest/api/person");
                              
 Person person = new Person();
 person.setId(1);
 person.setFname("John");
 person.setLname("Doe");                
 ClientResponse resp = service.type(MediaType.APPLICATION_JSON).post(ClientResponse.class, person);
    
 System.out.println(resp.getStatus()); //Always return 400 - Bad request

Any help is much appreciated.任何帮助深表感谢。 By the way I am using jersey 1.8.顺便说一句，我使用的是球衣 1.8。 I can make it work in latest Jersey version, but I need to make it work also in previous version of Jersey.我可以让它在最新的 Jersey 版本中工作，但我需要让它在以前版本的 Jersey 中也能工作。

您的createPerson()方法未使用@Path("/person")注释进行注释，其中 Path 的类型为javax.ws.rs.Path并且您的服务接口也需要使用@Path("/api")进行注释
