我已经构建了一个错误控制器,它应该是我在Spring REST服务中捕获异常的"最后一行".但是,我似乎无法将POJO作为响应类型返回.为什么杰克逊不为这个案子工作？

我的班级看起来像:

@RestController
public class CustomErrorController implements ErrorController
{
  private static final String PATH = "/error";

  @Override
  public String getErrorPath()
  {
     return PATH;
  }


  @RequestMapping (value = PATH)
  public ResponseEntity<WebErrorResponse> handleError(HttpStatus status, HttpServletRequest request)
  {
     WebErrorResponse response = new WebErrorResponse();

    // original requested URI
    String uri = String.valueOf(request.getAttribute(RequestDispatcher.FORWARD_REQUEST_URI));
    // status code
    String code = String.valueOf(request.getAttribute(RequestDispatcher.ERROR_STATUS_CODE));
    // status message
    String msg = String.valueOf(request.getAttribute(RequestDispatcher.ERROR_MESSAGE));

    response.title = "Internal Server Error";
    response.type = request.getMethod() + ": " + uri;
    response.code = Integer.valueOf(code);
    response.message …
