Google Guice is an open source Dependency Injection framework from Google. Guice is based on annotations and generics unlike Spring which depends on XML of Java for wiring dependencies. Guice injects constructors, fields and methods (any methods with any number of arguments, not just setters). Guice provides support for custom scopes, static member injection, Spring as well as Struts 2.x integration and AOP Alliance method interception. Guice is available at Google Code. You can find the User guide and Javadocs from there. This post describes how I implemented a simple Web application using Guice. For injecting dependencies into Servlets, I used a Listener (this idea was from Hani Suleiman in the Guice developer mailing list). Follow these steps to run the example.
