e 我正在尝试使用 JUnit 中的 Jersey 客户端对 REST 服务的 JSON 有效负载进行 POST 操作。这是我所做的：

资源类

@Path("/Users")
@Component
public class UserResource{
@POST
@Path("register")
@Consumes({MediaType.APPLICATION_JSON})
@Produces(MediaType.APPLICATION_JSON)
public String registerUser(RegisterRequestJSON requestJson)
{
         User user = userManager.getUserInformationByEmail(email);
        UserInfoJSON userInfoJSON = new UserInfoJSON();
        userInfoJSON.copyFromUserBean(user);
        GoodResponseObject gro = new GoodResponseObject(Status.OK.getStatusCode(), Status.OK.getReasonPhrase(), userInfoJSON);
        try {
            return Formatter.getAsJson(gro, true);
        } catch (Exception e) {
            throw new WebApplicationException(Response.status(Status.BAD_REQUEST).entity(e).build());
        } 
      }
  }

资源测试

String registerUserUrl = "http://localhost:9998/Users/Path";
    JSONObject inputJsonObj = new JSONObject();
    inputJsonObj.put("accessToken", userAccessToken );
    inputJsonObj.put("accessTokenType", "example" );
    ClientConfig clientConfigRegisterUser = new DefaultClientConfig();
    clientConfigRegisterUser.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING,Boolean.TRUE);
    Client clientRegisterUser = Client.create(clientConfigRegisterUser);
    WebResource registerUser = clientRegisterUser.resource(registerUserUrl); 
    String registerResponse = registerUser.type(MediaType.APPLICATION_JSON).post(String.class,registerJson);

当我运行测试时，我收到以下错误：

这里可能是什么问题？

您的客户端不知道如何序列化（写入）com.genie.account.mgmt.json.RegisterRequestJSON 参数以将其发送到 REST 端点。

默认情况下，Jersey 尝试使用 JAXB 序列化为 JSON/XML，但您的 RegisterRequestJSON 参数类型应该被注释

另一种选择是使用此答案中所述的自定义编写器/读取器：

在泽西岛，我如何让一些方法使用 POJO 映射功能而另一些不使用？
