Using a separate Controller for Interception

Question

I have created a Controller named InterceptionLogger.java which will contain only the Interception methods. The other Controller namely Application will contain all the action methods and use the Interception using the @With annotation.

This is the Application.java Controller:

@With(InterceptionLogger.class)
public class Application extends Controller {

public static void index() {
    System.out.println("Inside index!!!");
    render();
}

public static void welcome(String txtName){     
    render(txtName);
}

If the InterceptionLogger.java Controller is this:

public class InterceptionLogger extends Controller {   

@Before
static void logBefore(){
    System.out.println("Inside \"logBefore\" method of App Controller");
}

@After
static void logAfter(){
    System.out.println("Inside \"logAfter\" method of App Controller");
}

}

When I run the Application, the Output is:

Inside "logBefore" method of App Controller
Inside index!!!
Inside "logAfter" method of App Controller

Fine, as expected.

But If I change the InterceptionLogger.java to this:

public class InterceptionLogger extends Controller {   

@Before(only="welcome")
static void logBefore(){
    System.out.println("Inside \"logBefore\" method of App Controller");
}

@After(only="index")
static void logAfter(){
    System.out.println("Inside \"logAfter\" method of App Controller");
}

}

Then I am getting this output for index :

Inside index!!!

In this case, why is the statement Inside "logAfter" method of App Controller not getting printed in the console?

How to make it work?

Play! is looking for the intercepted methods in the current controller. You need to supply the full path, if the method is in another controller:

@Before(only="Application.welcome")
static void logBefore(){
    System.out.println("Inside \"logBefore\" method of App Controller");
}

@After(only="Application.index")
static void logAfter(){
    System.out.println("Inside \"logAfter\" method of App Controller");
}
