Spring Boot-自定义异常处理程序 [英] Spring boot - custom exceptions handler

问题描述

我正在使用Spring Boot开发一个rest应用程序。
此应用程序有一个自定义过滤器，仅允许在某些请求下访问。
如果用户需要特定资源，则过滤器将引发异常。
如何在全局级别处理此过滤器中生成的所有异常？

I'm developing a rest application with Spring boot. This application have a custom filter that allows access, only, at some requests. If the user require a particular resource the filter throw an exception. how can I handle all the exceptions generated in this filter at the global level?

我已经尝试过 @ControllerAdvice 批注但不起作用。

I have tried the @ControllerAdvice annotation but not working.

推荐答案

首先，您可能具有自定义的Exception Handler类，它将替换默认

First of all you may have your customized Exception Handler class, it will replace the default

ResponseEntityExceptionHandler

下面是我在学习期间使用的一个示例代码：

Below is one sample code I used during my studies:

@ControllerAdvice
@RestController
public class CustomizedResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(Exception.class)
    public final ResponseEntity<Object> handleAllExceptions(Exception ex, WebRequest request) {
        ExceptionResponse exceptionResponse = new ExceptionResponse(new Date(), ex.getMessage(), request.getDescription(false));
        return new ResponseEntity<>(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR);
    }

    @ExceptionHandler(UserNotFoundException.class)
    public final ResponseEntity<Object> handleUserNotFoundException(Exception ex, WebRequest request) {
        ExceptionResponse exceptionResponse = new ExceptionResponse(new Date(), ex.getMessage(), request.getDescription(false));
        return new ResponseEntity<>(exceptionResponse, HttpStatus.NOT_FOUND);
    }

    @Override
    protected ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex,               HttpHeaders headers, HttpStatus status, WebRequest request) {
        ExceptionResponse exceptionResponse = new ExceptionResponse(new Date(), "Validation Failed", ex.getBindingResult().toString());
        return new ResponseEntity<>(exceptionResponse, HttpStatus.BAD_REQUEST);
    }
}

然后您可以添加自定义的例外并补充响应

You can then add your customized Exceptions and complement the response object if you need it.
