使用@ControllerAdvice注解的类处理异常时丢失堆栈跟踪

Question

我有一个Spring REST应用程序。我抛出了控制器的所有异常，并将它们处理在一个常见的地方，一个名为ExceptionHandlerControllerAdvice的类使用@ControllerAdvice注解。在那里，我有多个使用@ExceptionHandler注解的方法来处理每种类型的异常。在这些方法中，我发送自定义错误json响应。在将这个错误json发送给使用者之前，我在日志中发现异常的堆栈跟踪。看代码 -

@ControllerAdvice 
public class ExceptionHandlerControllerAdvice { 

    private static Logger logger = LoggerFactory.getLogger(ExceptionHandlerControllerAdvice.class); 

    @ExceptionHandler(value = { Exception1.class }) 
    public @ResponseBody ResponseEntity<ErrorMessage> Exception1Handler(HttpServletRequest request, Exception1 e) { 
     logger.error("error message {}. Details:", e.getMessage(), e.fillInStackTrace()); 
     return new ResponseEntity<ErrorMessage>(new ErrorMessageBO(e.getErrorCode(), e.getMessage()), HttpStatus.OK); 
    } 

    @ExceptionHandler(value = { Exception2.class }) 
    public @ResponseBody ResponseEntity<ErrorMessage> Exception2Handler(HttpServletRequest request, Exception2 e) { 
     logger.error("error message {}. Details:", e.getMessage(), e.fillInStackTrace()); 
     return new ResponseEntity<ErrorMessage>(new ErrorMessageBO(e.getErrorCode(), e.getMessage()), HttpStatus.OK); 
    } 
} 

问题是，我失去了实际的堆栈跟踪，它确切地告诉我异常来自哪里。任何人都熟悉这个问题？

Answer 1

从你的日志格式来看，它看起来像你正在使用slf4j。 API的warn和error方法经常用于记录异常，而slf4j提供特定的warn(String message, Throwable t)覆盖，这些覆盖可以在记录器实现中使用异常特定的格式（例如，打印消息和堆栈跟踪的前N行）。由于这些消息几乎不会被压制，所以不会因为不参数化消息字符串而丢失任何东西。只需写logger.warn("message", ex);。

至于你为什么在第一个问题，你应该使用getStackTrace()而不是fillInStackTrace()。
