Class SimplePageAuthorizationStrategy

java.lang.Object
  org.apache.wicket.authorization.strategies.page.AbstractPageAuthorizationStrategy
      org.apache.wicket.authorization.strategies.page.SimplePageAuthorizationStrategy

All Implemented Interfaces:

IAuthorizationStrategy

public abstract class SimplePageAuthorizationStrategy
extends AbstractPageAuthorizationStrategy

A very simple authorization strategy that takes a supertype (a base class or tagging interface) and performs a simple authorization check by calling the abstract method isAuthorized() whenever a Page class that extends or implements the supertype is about to be instantiated. If that method returns true, page instantiation proceeds normally. If it returns false, the user is automatically directed to the specified sign-in page for authentication, which will presumably allow authorization to succeed once they have signed in.

In your Application.init() method do something like the following:

 SimplePageAuthorizationStrategy authorizationStrategy = new SimplePageAuthorizationStrategy(
                MySecureWebPage.class, MySignInPage.class)
 {
        protected boolean isAuthorized()
        {
                // Authorize access based on user authentication in the session
                return (((MySession)Session.get()).isSignedIn());
        }
 };
 
 getSecuritySettings().setAuthorizationStrategy(authorizationStrategy);
