java - 来自 Java 应用程序客户端的 Jersey POST 请求

Question

我有一个 Java 应用程序客户端，我想向服务器发出发布请求。 这是我的SecretaryResource POST 服务

@POST
 @Consumes(MediaType.APPLICATION_XML)
 public Secretary addSecretary(Secretary sec)
 {
      return secService.addSecretary(sec);

 }

这是我的客户端方法:

public boolean addSecretary()
    {
       Client client = ClientBuilder.newClient();
        WebTarget target = client.target("http://localhost:8080/ClinicManager/webapi/secretary");

Form form = new Form();
form.param("id","hardcoded");
form.param("password","hardcoded");
form.param("name", "hardcodedname");

Secretary bean =
target.request(MediaType.APPLICATION_XML)
   .post(Entity.entity(form,MediaType.APPLICATION_FORM_URLENCODED_TYPE),
         Secretary.class);


return true;


    }

我得到了这个异常

我也尝试过这种方式。仍然不起作用:

 Client client = ClientBuilder.newClient( new ClientConfig().register( LoggingFilter.class ) );
WebTarget webTarget = client.target("http://localhost:8080").path("/ClinicManager/webapi/secretary");

Secretary sec = new Secretary();
sec.setId(100);
sec.setName("David Feezor");
sec.setPassword("parola");

Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
Response response = invocationBuilder.post(Entity.entity(sec, MediaType.APPLICATION_JSON));

我用 Postman 测试了 POST 服务，它工作正常。错误的部分来自客户端。请帮助我!

我认为问题是您的内容类型不匹配。服务器接受 xml(MediaType.APPLICATION_XML 又名 application/xml)，但您发布编码为 MediaType.APPLICATION_FORM_URLENCODED_TYPE 又名 application/的表单数据x-www-form-urlencoded

我想您需要决定一种格式。如何执行此操作以及使用什么转换取决于您。
