Guice don't inject to Jersey's resources

Question

Parsed allover the whole internet, but can\'t figure out why this happens. I\'ve got a simplest possible project (over jersey-quickstart-grizzly2 archetype) with one Jersey

Answer 1

Yes, in my opinion the answer above is correct. A very good way is to bridge Guice to HK2. I am not 100% sure if it neccessary to create a new TransportModule in the code above. Indeed Guice registers its injector in the ServletContext with the class name of Injector anyway, so it can be fetched from there:

        register(new ContainerLifecycleListener() {
        public void onStartup(Container container) {
            ServletContainer servletContainer = (ServletContainer)container;
            ServiceLocator serviceLocator = container.getApplicationHandler().getServiceLocator();
            GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);
            GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);
            Injector injector = (Injector) servletContainer.getServletContext().getAttribute(Injector.class.getName());
            guiceBridge.bridgeGuiceInjector(injector);
        }
        public void onReload(Container container) {
        }
        public void onShutdown(Container container) {
        }       
    });

Beside that it is not trivial how to configure the REST Endpoints in that way, so I wrote detailled blog about that here.
