Spring Framework features and advantages?

Hi All,
I am new to this Spring framework and as i came to know from some previous posts that it has so many advantages over struts.
But i guess all the advantages are related to easy development and maintanence.Is there anything in spring framework which is good performance wise or are there any other features which i can count as advantages over struts and should migrate my existing struts app. to spring framework.
One more question Does this Spring framework has components like JSF?
Please if somebody can list down Spring framework features for me that would be really helpful for me to make my decision.

Thanks a lot

Rod Johnson wrote an introductory article some time ago that was published at TSS. Have you read that already?

Anshu,

The basic featureset of Spring is:

* Inversion of Control container
* AOP
* Data Access integration (JDBC, JDO, Hibernate, OJB)
* J2EE integration (EJB, JMS, JNDI)
* Spring MVC framework
* Extensive MVC view support (JSF, Tapestry, JSTL, Velocity, JasperReports, Excel, PDF)
* Remoting (JAX-RPC, Hessian, Burlap)
* Enterprise Services (Transaction management, pooling etc)

There are a few more features than this, but this is the main list.
