Writing custom filters for Play! 2.2 in Java

Question

I have a simple scenario: automatically add a response header to every HTTP response; and I want to do this in Java.

Looking at src/play-filters-helpers/src/ma

Answer 1

To add a custom filter (MyFilter.class) create a Global.java file in the root package. Tested in PlayFramework 2.3.x and Java (JDK8)

import play.GlobalSettings;
import play.api.mvc.EssentialFilter;

public class Global extends GlobalSettings {
    @Override
    public  Class[] filters() {
        return new Class[]{MyFilter.class};
    }
}
