@Slf4j @ControllerAdvice public class GlobalExceptionHandler { /** * @ExceptionHandler 可以指定捕获特定的异常 */ @ResponseBody @ExceptionHandler(value = Exception.class) public ResponseEntity<String> exceptionHandler(HttpServletRequest request, HttpServletResponse response, Exception e){ log.error("服务器异常: {}", e); return new ResponseEntity<>().error("服务器出错啦"); } }
