Spring MVC-ExceptionHandler

Question

我使用的是Spring Boot1.5.7。我有一个ExceptionHandler用于返回ResponseEntity的异常

@ExceptionHandler(MyException.class)
public ResponseEntity<ResponseExceptionEntity> handleException(MyException e) {
    return ResponseEntity
        .status(HttpStatus.BAD_REQUEST)
        .body(new ResponseExceptionEntity(e));
}     

在返回ResponseEntity/@responseBody（JSON/XML响应）的api调用期间发生异常的情况下，这种方法工作得很好

null

Answer 1

是的，您可以编写两个异常处理程序来处理api和html请求异常。下面是演示解决方案的示例代码。

@ControllerAdvice(annotations = RestController.class)
@Order(1)
class RestExceptionHandler {
    @ExceptionHandler(MyException.class)
    @ResponseBody
    ResponseEntity<ErrorResponse> exceptionHandler() {
        ....
    }
}

@ControllerAdvice(annotations = Controller.class)
@Order(2)
class ExceptionHandler {
    @ExceptionHandler(Exception.class)
    public ModelAndView handleError500(HttpServletRequest request, HttpServletResponse response, Exception ex) {
        ModelAndView mav = new ModelAndView("error");
        mav.addObject("error", "500");
        return mav;
    }
}
