Guice is a lightweight dependency injection framework for Java 5 from the house of google. Guice injects constructors, fields and methods (any methods with any number of arguments, not just setters). Guice includes advanced features such as custom scopes, circular dependencies, static member injection, Spring integration, and AOP Alliance method interception etc. See more on this project page.
This site includes the UML models of some great open source projects like JBoss, Spring, Hibernate etc. Its really helping me to understand this frameworks.,
Three advantages of integrating Struts into Spring
There are so many advantages of integrating a Struts application into the Spring framework. These three points I got from Mr.George Franciscus’s article in Developerworks.
1. Spring was explicitly designed to resolve some of the real-world problems of JEE, such as complexity, poor performance, testability, and much more.
2. The Spring framework includes an AOP implementation that lets you apply aspect-oriented techniques to normal object-oriented code.
3. Some might say that the Spring framework just handles Struts better than Struts handles itself 🙂
