Spring ExceptionHandler Logging Not Working

Question

I created ExcpetionHandler class which annotated with @ControllerAdivce annotation which working fine using eclipse tomcat server.

While I build the project and deploy it to tomcat on some unix machine , the exceptionHandler not getting triggerd.

I noticed that some log4j warning getting generated only on the unix machine .

The log4j xml is configured and all appenders are working .

Only after adding the below class I start to get the below log4j messages.

Any idea ?

@ControllerAdvice
public class ExceptionController {

    @ExceptionHandler(RuntimeException.class)
    public ResponseEntity<ClientErrorMessage> handleRunTimeException(HttpServletRequest request, RuntimeException exception) {
       ClientErrorMessage message = SOME_MESSAGE
       return new ResponseEntity<>(message, HttpStatus.INTERNAL_SERVER_ERROR);
    }

}

log4j:WARN No appenders could be found for logger (org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Looks like the log4j.XML is not in the classpath of your application — Jens, Jun 29 '16 at 13:51
It is , if not all other appenders shouldn't work as well but they are working. — Amir_Af, Jun 29 '16 at 13:52
I provided the path by providing JAVA_OPTS -Dlog4j.configuration. I might found the issue , will test it and update. i think i need to add appender for org.springframework.web package. currently i don't have appender for this. — Amir_Af, Jun 29 '16 at 13:56
Yes, the issue was missing appender for the spring web package. Thanks for the help — Amir_Af, Jun 29 '16 at 14:03

You can check the following link for your question. It seems that you are using logger instance before configuring log4j

No appenders could be found for logger(log4j)?

Issue was missing log4j appender for the spring package.

<logger name="org.springframework.web">
  <level value="debug"/>
  <appender-ref ref="CONSOLE"/>
</logger>
