Spring or Google Guice use dependency injection so you can focus on your core application and let the framework handle infrastructural concerns. Dependency Injection explores the DI idiom in fine detail, with numerous practical examples that show you the payoffs. You'll apply key techniques in Spring and Guice and learn important pitfalls, corner-cases, and design patterns. Dhanji R.
