Is it possible to intercept any call to a method of a class?

In our project we're using Spring Framework and now I need to intercept any method call to any object method. Does Spring provide such a facility? I mean, for instance we have a method:

public void m(){
    MyClass a = new MyClass();
    a.method(); //I need to intercept that method call and invoke some stuff
}

Is such a thing possible?

Yes, it's possible - you'll need to use AOP. If you want to intercept every call of a method from spring managed bean then Spring AOP java proxying will be sufficient. Otherwise you'll need to use AspectJ.

You need to include Spring AOP in you project.

An option to intercept any call for methods defined in MyClass is:

@Around("* my.application.MyClass.*(..)")
public Object interceptAnyMethodCall(ProceedingJoinPoint pjp) throws Throwable {

    Object retVal = pjp.proceed();

    // ... your code

    return retVal;
}
