Question

Person.java

@XmlRootElement
public class Person {

    private int id;
    private String fname;
    private String lname;
    //private Address address = new Address();

    public Person() {        
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getFname() {
        return fname;
    }

    public void setFname(String fname) {
        this.fname = fname;
    }

    public String getLname() {
        return lname;
    }

    public void setLname(String lname) {
        this.lname = lname;
    }
}

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 ===========");
}

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 ===========");
}

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

非常感谢任何帮助。顺便说一句，我使用的是1.8号球衣。我可以使它在最新泽西版本中运行，但我需要在之前版本的Jersey中使它工作。

Apache Tomcat服务器日志输出:(但我认为它不会影响400 - 错误请求吗？）

Answer 1

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，您的服务接口也需要使用@Path("/api")进行注释

总是得到400 - 在REST / JAX-RS中发布数据时的错误请求
