404 Error on using Spring AOP Logging - spring

Question

I was trying to add AOP logger to the existing Spring(v3.1.3) application. Below is the code for the same.
Application launches successfully and am able to login. But, once the flow reaches the Controller that's specified in the ApplicationLogger.java, am getting 404 error in the screen and unfortunately aint getting any error trace in the console. Not getting any clue.
Kindly help me out to find where i have gone wrong.
TIA,
Arun

Answer 1

AbstractPolicyController was actually implementing an interface and servlet couldnt inject a proxy for the same (Investigating on the reason.) On removing the 'implements interfaceName' it worked good. Anyone who know the reason may pls let me know.
