从Spring Exception Handler返回JSON响应

Question

I'm using below mentioned Spring code to handle exception and return response to client. Since I have used ResponseBody annotation here , I was expecting spring to return JSON response in case of error but I see below response received at client end (JSON response is inside responseText instead of directly return to client). Please advice how I can return JSON response to Caller-

Response received at Client End :-

Object {readyState: 4, responseText: "{"status":false,"msg":"User Data not available","r…"MARSAPI003","noOfRecords":0,"responseList":null}", responseJSON: Object, status: 403, statusText: "Forbidden"}

Spring Code :-

@ExceptionHandler(MarsUnAuthorizedOperation.class)
@ResponseBody
@ResponseStatus(value=HttpStatus.FORBIDDEN)
public MarsResponse unAuthorizedOperationExceptionHandler(final Exception ex){
    final MarsResponse response = new MarsResponse();
    response.setNoOfRecords(0);
    response.setMsg(ex.getMessage());
    response.setResponseCode(marsMessageProperties.getUnauthorizedOperationErrorCd());
    response.setResponseMessage(marsMessageProperties.getUnauthorizedOperationErrorMsg());
    response.setStatus(false);
    return response;
}

Answer 1

I think it's your @ResponseBody annotation that is preventing spring from marshalling your MarsResponse Object to a JSON Object. Try removing that and checking again.
