Spring Boot returns Whitelabel Error Page instead of JSON

Question

I need RESTful service to return JSON every time regardless if there is error or not. With normal cases everything goes ok, but when exceptions come I see Whitelabel Error Page .

I tried to resolve this in two ways.

Through @ExceptionHandler inside @Controller class inside the class annotated with @RestController:

@ExceptionHandler(MyCustomException.class)
@ResponseBody
public ErrorResponse handleException(Exception e) {
    return new ErrorResponse(5, "Error message");

}

And through special class with @ControllerAdvice annotation:

@ControllerAdvice
public class ExceptionController {

    @ExceptionHandler(MyCustomException.class)
    @ResponseBody
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public ErrorResponse handleSecurityException(MyCustomException e) {
        return new ErrorResponse(5, "Error message");
    }

}

In both cases through breakpoints I see that those methods was called, but I still receive Whitelabel Error Page .

So what am I missing or doing wrong?

问题是我忘了为ErrorResponse类实现getter和setter。
