Java: printing each method invoked to the console?

Question

I need to understand a fairly large Java project. I look through it using eclipse and use the call hierarchy and that’s it, but that doesn’t give me enough idea of ​​what happens when the project starts (this is a web service).

Is it possible to print every method call using parameters for the console? Basically what puts

System.out.println("methodName, params: " + param1.toString()); 

in every method for me. Some kind of structure that provides this, for example?

You should try using Aspect Oriented Programming (AOP).

Here is an example that does more or less what you want: How to use AOP with AspectJ for logging?
