I have implemented AspectJ in my application in Spring MVC framework.I can track entry point and exit point of the function calls, but unable to get the actual line number from the source file.It's showing the line number of the Logger class where pointcuts and advices are placed.

Maybe your problem ist similar to this one, so hopefully the solution is the same for you:

joinPoint.getSourceLocation().getLine()

This works for real AspectJ (via LTW), but maybe not for Spring AOP which is just some kind of proxy-based "AOP lite" framework. For more information about how to configure Spring for AspectJ see the user manual, section 10.8, Using AspectJ with Spring applications.

  • Giving me exception and my version is 3.0 – 619 Jan 23 '16 at 13:24
  • Read my answer here and the linked one carefully, and you will know what is wrong. By the way, "giving me exception" is not very descriptive. – kriegaex Jan 23 '16 at 14:43

I do not know if there is a special AspectJ feature for this task, if not then you could obtain a StackTrace and then use StackTraceElement.getLineNumber().

//StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
Exception e =...
e.getStackTraceElement[]
stackTrace[stackTrace.length - 1].getLineNumber();
