Java: How to listen on methods invocation without registering each object explicitely?

Question

I want to listen on method calls in order to attach additional behavior dynamically around the call. I\'ve already done it on JUnit methods with a custom annotation and runner.

Well,this is commonly seen with Spring Framework and Aspect Oriented Programming. Since you delegate your constructor calls to Spring, it is quite easy for Spring to put a proxy in place to intercept calls to the actual objects.

As far as I can tell, the only way to intercept calls is to use a proxy. Either in the way you mentioned or using Spring and AOP.
