Problem with CustomizableTraceInterceptor

[neeraj_cmu]

CustomizableTraceInterceptor has a feature by which I could ask AOP to put the log message under the object being intercepted. So instead of logs appearing as

org.springframework.aop.interceptor.CustomizableTraceInterceptor:invokeUnderTrace

I would like the logs to appear as

com.mycompany.web.aop.CustomInterceptor:methodName

This feature is not working. It's not working because inherently it seems log4j and commons log don't support creating logger for a different class. For example let's look at this class.

public class A {
	public void testing() {
		Logger log = Logger.getLogger(B.class);
		log.debug("### testing");
	}
}

The generated log message is

com.mycompany.A:test:4) - ### testing

Here I am using log4j and I have created logger for class 'B'. Even though the logger is created for classs 'B' the generated log has 'com.mycompany.A' instead of 'com.mycompany.B'.

Am I missing something here?

The problem was the configuration with my log4j.properties file.

This is what I had

log4j.appender.stdout.layout.ConversionPattern=%p [%t] %C.%M(%L) | %m%n

Notice the capital "C". As per the log4j doc

%C: Outputs the fully-qualified class name of the caller issuing the logging request.


%c: Outputs the category of the logging event.

Switching from uppercase 'C' to lowercase 'c' solved the problem.
