Google Guice

Google Guice, or Guice for short (pronounced 'juice') is a lightweight dependency injection framework from Google, for Java 5 and later.

Guice is distributed under the open source Apache License.

Guice uses "@interface" annotation to wire the beans which is easier than wiring beans with XML and faster than autowiring. Guice users find this easier and smaller compared to other frameworks.

Guice-like dependency injection, on the other hand, requires changes to the annotations, i.e. the source code, when you want to inject a different implementation of some service, and annotations require additional imports in the source code.Wiring with XML separates the configuration from the source code.
