How can I automate logging

Question

So idea is to write a code which would add some predefined code snippets

eg I want to

1. Generate class field com.ck.MyClass.DEBUGGER initialized as org.apache.commons.logging.LogFactory.getLog("DEBUGGER." + MyClass.CNAME);

2. add these below lines at entry point and exit point of all methods except constructors in a class through java code for all the classes present in my project

    final String methodName = "process()"; if (MyClass.DEBUGGER.isDebugEnabled()) { MyClass.DEBUGGER.debug(CommonLoggingConstants.METHOD_ENTRY + MyClass.CNAME + CommonLoggingConstants.HASH + methodName); } 

What would be the best approach and API to address this requirement?

You could try to use AOP to intercept all the methods in your application and achieve your goal. You can read more about it here .
