Java Rest Service Jersey用户定义的异常处理

Question

我使用Jersey实现创建了Java Rest服务。 我的要求是在我的Rest服务中抛出UserDefined Exception 我创建了Exception类和ExceptionMapper类

这是我的Java代码：

public class AppServerException extends Exception {

    private String errorMessage;
    private int errorId;
    private static final long serialVersionUID = 1L;

    // Parameterless Constructor
    public IT360AppServerException() {
    }

    // Constructor that accepts a message
    public IT360AppServerException(String message, int errorid) {
        super(message);
        errorMessage = message;
        errorId = errorid;

    }

    public String getErrorMessage() {
        return errorMessage;
    }

    public int getErrorId() {
        return errorId;
    }

}

ExceptionMapper类：

         @Provider
        public class AppServerExceptionMapper implements
                ExceptionMapper<AppServerException> {

            @Override
            public Response toResponse(AppServerException exception) {
                System.out.println("toResponse>>");
                System.out.println("Error Code >>>>"+exception.getErrorId());////printing
                System.out.println("Error Message >>>"+exception.getErrorMessage());//printing

                ErrorResponse errorResponse = new ErrorResponse();
                errorResponse.setErrorCode(exception.getErrorMessage());
                errorResponse.setErrorId(exception.getErrorId());
                return Response.status(Response.Status.INTERNAL_SERVER_ERROR)
                        .entity(errorResponse).type(MediaType.APPLICATION_JSON).build();
            }

        }

问题： 我可以在toResponse()方法中打印日志，但响应没有返回.Flow正在停止日志本身。可以任何帮助

RestService：

@POST
@Path("/update")
@Consumes("application/json")
@Produces("application/json")
public Response updateIT30(String json,
        @HeaderParam("authorization") String authString)
        throws UserAuthenticationException, IT360AppServerException {
    System.out.println(" JSON Format" + json);
try{

            response = client.execute(post);

}
    catch(ConnectException e){
            throw new IT360AppServerException("App Server is down", 403);


        }


}
