Spring Boot 2.3 中未打印自定义异常的堆栈跟踪

Question

Error stacktrace is not printed in console for the custom exception that is annotated with @ResponseStatus

@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public class InternalErrorException extends RuntimeException {

  public InternalErrorException(String message) {
    super(message);
  }

  public InternalErrorException(String message, Throwable throwable) {
    super(message, throwable);
  }
}

Throwing exception like throw new InternalErrorException("error", e) , never get the stacktrace printed in the console unlesss I remove the annotation @ResponseStatus

How could I get it printed while keeping the annotation @ResponseStatus ?

Answer 1

See Annotation Type ResponseStatus API doc .

Warning: when using this annotation on an exception class, or when setting the reason attribute of this annotation, the HttpServletResponse.sendError method will be used.

With HttpServletResponse.sendError, the response is considered complete and should not be written to any further. Furthermore, the Servlet container will typically write an HTML error page therefore making the use of a reason unsuitable for REST APIs. For such cases it is preferable to use a ResponseEntity as a return type and avoid the use of @ResponseStatus altogether.

HttpServletResponse.sendError does not throw your error and I guess it is never logged because of that.

Maybe you want to implement exception handler for that exception to get it logged.
