How to add a Session / User object after bootstrap?

Question

There are examples when various types of objects are introduced into the presenter, but I cannot find an explanation of how this can be done.

In the Bootstrap-Code example, they enter, for example. a SecurityDelegate .

Also in the Gatekeeper example, I see things being introduced, for example. MyGatekeeper , but how to do it?

I want to first check if the user is registered, and then create a CurrentSession object or something like this. But how can I pass / paste this object around?

I'm currently initializing a singleton object, CurrentUser , which is kind of ugly imho. I would like to get GWTP support, but how?

---

Take this CurrentSession example, which is entered into the gatekeeper:

 @DefaultGatekeeper public class LoggedInGatekeeper implements Gatekeeper { private final CurrentSession currentSession; @Inject LoggedInGatekeeper(CurrentSession currentSession) { this.currentSession = currentSession; } @Override public boolean canReveal() { return currentSession.isLoggedIn(); } } 

How do I insert CurrentSession here?

Here is a tutorial that explains how to use the gatekeeper: http://dev.arcbees.com/gwtp/tutorials/tutorial-part2.html

Declare the CurrentSession class (CurrentUser in the tutorial) as Singleton in your Gin module, as shown below:

 public class YourGinModule extends AbstractGinModule { @Override protected void configure() { bind( CurrentSession.class ).in ( Singleton.class ); ... } } 

Here you can find another example using GWTP Gatekeeper on the client side and Spring Security on the server side: https://github.com/imrabti/gwtp-spring-security
