What is Spring ? and What are the Benefits/Advantages of Using Spring Framework ?

Spring is an open source framework created to address the complexity of enterprise application development.
*Lightweight container
*No App Server Dependent ? like EJB JNDI Calls
*Objects are created Lazily , Singleton - configuration
*Components can added Declaratively
Initialization of properties is easy ? no need to read from properties file
*Declarative transaction, security and logging service - AOP
application code is much easier to unit test
*With a Dependency Injection approach, dependencies are explicit, and evident in constructor or JavaBean properties
*Spring's configuration management services can be used in any architectural layer, in whatever runtime environment.
*Spring can effectively organize your middle tier objects
*not requires special deployment steps
