Google Guice

Guice (pronounced “Juice”) is the Jolt Award-winning, 100% Java icing on the cake of Java dependency injection. Unlike other popular dependency injection frameworks such as Spring, Guice fully embraces modern Java language features and combines simplicity with stunning performance and developer–friendliness.

Google Guice: Agile Lightweight Dependency Injection Framework will not only tell you “how,” it will also tell you “why” and “why not,” so that all the knowledge you gain will be as widely applicable as possible. Filled with examples and background information, this book is an invaluable addition to your knowledge of modern agile Java.
