为@ExceptionHandler中的每个异常生成正确的状态

@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(NullPointerException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ResponseBody
    public Map<String, Object> handleNullPointerException(NullPointerException ex) {
        Map<String, Object> response = new HashMap<>();
        response.put("status", "error");
        response.put("message", "空指针异常");
        return response;
    }

    @ExceptionHandler(ArithmeticException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ResponseBody
    public Map<String, Object> handleArithmeticException(ArithmeticException ex) {
        Map<String, Object> response = new HashMap<>();
        response.put("status", "error");
        response.put("message", "算术异常");
        return response;
    }
