Java code instrumentation using annotations

Question

I've got a huge java project with tons of code. Let us assume it looks like:

fn1(int arg1){...}
fn2(int arg1,int arg2){...}
fn23(){...}
...
fn134(){...}

I want to log each invocation of functions using annotations:

@logme("arg1")
fn1(int arg1){...}
@logme("all args")
fn2(int arg1,int arg2){...}
fn23(){...}
...
fn134(){...}

and expect seeing

fn1(arg1=223)
fn1(arg1=213,arg2=46)

in my log files

Would you be so kind to propose me some tool?

I would recommend to use AspectJ for this purpose. Here you can find a short documentation how to define the appropriate PointCuts
