exception-handling - 如何处理@ControllerAdvice 中所有未处理的异常？

Question

我使用这个异常处理程序来处理我的 Spring Boot 应用程序(REST API)中的一些特定异常:

@ControllerAdvice
class GlobalExceptionHandler {

    @ExceptionHandler(NotFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public
    @ResponseBody
    ResponseMessage notFound(NotFoundException ex) {
        return new NotFoundResponseMessage(ex.getMessage());
    }

    @ResponseStatus(value = HttpStatus.UNSUPPORTED_MEDIA_TYPE)
    @ExceptionHandler(HttpMediaTypeNotSupportedException.class)
    public
    @ResponseBody
    ResponseMessage unsupportedMediaType(HttpMediaTypeNotSupportedException ex) {
        return new UnsupportedMediaTypeResponseMessage(ex.getMessage());
    }

    @ExceptionHandler(UnauthorizedException.class)
    @ResponseStatus(HttpStatus.UNAUTHORIZED)
    public
    @ResponseBody
    ResponseMessage unauthorized(UnauthorizedException ex) {
        return new UnauthorizedResponseMessage(ex.getMessage());
    }

    @ExceptionHandler(HttpRequestMethodNotSupportedException.class)
    @ResponseStatus(HttpStatus.METHOD_NOT_ALLOWED)
    public
    @ResponseBody
    ResponseMessage methodNotAllowed(HttpRequestMethodNotSupportedException ex) {
        return new MethodNotAllowedResponseMessage(ex.getMessage());
    }

    @ExceptionHandler(ForbiddenException.class)
    @ResponseStatus(HttpStatus.FORBIDDEN)
    public
    @ResponseBody
    ResponseMessage forbidden(ForbiddenException ex) {
        return new ForbiddenResponseMessage(ex.getMessage());
    }

}

我想用一种“全局”处理方法处理所有其他异常。但是我需要在此方法中获取 HTTP 状态代码来处理错误消息等。

问题

有什么方法可以将所有未处理的异常重定向到一个特定的方法中吗？我该怎么做？

见 docs :

Any Spring bean declared in the DispatcherServlet’s application context that implements HandlerExceptionResolver will be used to intercept and process any exception raised in the MVC system and not handled by a Controller.

public interface HandlerExceptionResolver {
    ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex);
}
