Spring Framework is one of the most popular Java EE frameworks. It is an open-source and lightweight framework created by Rod Johnson in June 2003.

Core principles of Spring Framework:

1. Aspect Oriented Programming (AOP).
2. Dependency Injection (DI).

Advantages of Spring Framework:

1. Lightweight:

1. Spring framework is a lightweight framework because of its POJO model implementation.

2. Non-invasive approach:

1. As we know struts force a programmer to extend the Action Class but Spring framework doesn’t force a programmer to extend class or implement interface given by Spring API.

3. Loose Coupling:

1. Because of the dependency injection concept, spring objects are loosely coupled.

4. Modular fashion:

1. Spring framework is designed in a modular fashion. A programmer can use only needed modules and ignore the rest.

5. Easy Testing:

1. Dependency injection and the POJO model make it easy to test an application.

6. Transaction management interface:

1. Spring framework provides a transaction management interface for transaction management.

7. No need for an application server:

1. Struts or EJB applications require an application server to run but a spring application doesn’t need an application server.

8. MVC framework:

Spring framework is a great alternative to web MVC frameworks like Struts.
