如何在spring中使用@ControllerAdvice处理异常，即使我们在catch块中处理异常

Question

无法使用由try和catch块包围的@controlleradvice和@afterthollow when方法。

我可以一步一步解释

@RequestMapping(value = "/service/getDetails", method = RequestMethod.POST, produces = { "application/json" })
public ResponseEntity<Map<String, Object>> getDetails(@RequestBody Details details, HttpServletRequest request) {
    ResponseEntity<Map<String, Object>> response = null;
    try {
        /// Some code
    } catch (Exception e) {
        logger.error("Exception while DetailsController: " + e.getMessage());
        response = new ResponseEntity<>(HttpStatus.BAD_REQUEST);
        /*
         * int status=response.getStatusCodeValue();
         * scheduledMailTrigerService.sendErrorLogInfo(request,e,status);
         */
    }
    return response;
}

  @ControllerAdvice
  public class AppExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(value = { Exception.class })
public String handleAnyException(Exception ex, WebRequest request) {
    System.out.println("Done");
    return "Done";
}

}

您可以使用@around建议来捕获方法执行的结果...我的建议是从所有endpoint中删除try catch，只需编写一个try catch来包装procedingJoinPointprocede()执行。这样，在执行电子邮件发送逻辑的同时，当异常发生时，您可以返回ResponseEntity 400。
