无法读取错误消息：AngularJS-Spring 4

Question

I'm trying to develop a Web application using AngularJS + Spring4. 我正在尝试使用AngularJS + Spring4开发Web应用程序。

What i want to do: 我想做的事：

1.If http request is success, needs to send response data as JSON 1.如果http请求成功，则需要以JSON格式发送响应数据
2.In case of an exception, needs to send custom error message (will be shown to the user in alert box) 2.如果发生异常，则需要发送自定义错误消息（将在警报框中显示给用户）

Spring controller class: 弹簧控制器类：

@RequestMapping(value = "/loadAllUsers", method = RequestMethod.POST)
@ResponseBody
public String loadAllUsers(@RequestBody String paramsJsonStr,ModelMap model,HttpServletRequest request, HttpServletResponse response) throws IOException {

String responseJSONStr = null;
ResponseJSON responseJSON = new ResponseJSON(); //Custom class for sending response data 

try {
    .....
    .....
    List<User> users = this.loadAllUsers();
    responseJSON.setIsSuccessful(true);
    responseJSON.setData(schemas);
    responseJSONStr = JSONUtilities.toJson(responseJSON);
}catch (CustomException e) {
    e.printStackTrace();
    response.sendError(e.getErrorCode(), e.getErrorMessage());
}

   return responseJSONStr;
}

AngularJs controller: AngularJs控制器：

$http.post("loadAllUsers",{})
.success(function(data){
    console.log('success handler');
    console.log(data);
})
.error(function(error) {
    console.log('error handler');
    console.log(error);
    console.log(error.status);
    console.log(error.data);
    console.log(error.statusText );
    console.log(error.headers);
    console.log(error.config);
})

Problem : Not able to read error message , but able to read the success data. 问题：无法读取错误消息，但是能够读取成功数据。

when i print the error in console am getting this HTML tags: 当我在控制台中打印错误时，得到此HTML标签：

<html><head><title>Error</title></head><body>Invalid input.</body></html>

How to parse this error message in AngularJS ? 如何在AngularJS中解析此错误消息？ Is this the correct way to send error message from spring ?? 这是从Spring发送错误消息的正确方法吗？

If i send the error message also in same JSON "responseJSONStr", it'll be processes in success handler of the AngularJS as response will be considered as success in this case. 如果我也以相同的JSON“ responseJSONStr”发送错误消息，它将是AngularJS成功处理程序中的进程，因为在这种情况下，响应将被视为成功。

Any guidance will be very helpful. 任何指导都将非常有帮助。 Thanks in advance :) 提前致谢：）

In case anyone in future tried to do the same this may help.. To achieve this, instead of using "response.sendError" a failure status code can be set using "response.setStatus" and error message can be set in responseJSON with isSuccessful as "false" as below 如果将来有人尝试这样做，可能会有所帮助。.要实现此目的，可以使用“ response.setStatus”设置故障状态代码，而不是使用“ response.sendError”，并且可以使用isSuccessful在responseJSON中设置错误消息如下所示为“ false”

@RequestMapping(value = "/loadAllUsers", method = RequestMethod.POST)
@ResponseBody
public String loadAllUsers(@RequestBody String paramsJsonStr,ModelMap model,HttpServletRequest request, HttpServletResponse response) throws IOException {

String responseJSONStr = null;
ResponseJSON responseJSON = new ResponseJSON(); //Custom class for sending response data 

try {
     .....
     .....
     List<User> users = this.loadAllUsers();
     responseJSON.setIsSuccessful(true);
     responseJSON.setData(schemas);
}catch (CustomException e) {
     e.printStackTrace();
     response.setStatus(e.getErrorCode()); //http failure status code as per respective error
     responseJSON.setIsSuccessful(false);
     responseJSON.setMessage(e.getErrorMessage());
}

 responseJSONStr = JSONUtilities.toJson(responseJSON);
 return responseJSONStr;
}
