Take method argument as an argument in the annotation in Java 8

Question

I have looked up and till now it doesn't seem possible, so, if that's the case, what is the best alternative to meet the following requirement?

@Authentication_Annotation(id, password)
public void method(String id, String password, String param) {
    // Does something if ID and Password are correct.
}

Coming from a python background, this would have been possible using decorators. Can we still do it in java, without calling a method that authenticates every time a method needs to be provided authentication?

Answer 1

You can access method args directly in your annotation instead of passing it as arguments explicitly.

Using AOP: Get method arguments using Spring AOP?

Anyways there seems to be another way via reflection using DynamicProxy: Java method missing (ala Ruby) for decorating?

Answer 2

It is impossible in Java (at least without ungodly amount of very dark black magic).
