Run & Test

Benefit of using spring platform You can method execute without having any deal.

In project number of classes and packages are important, you can worry about only essential component and other component to ignore it.

You can build enterprise applications using "plain old Java objects" (POJOs).

Easy to implement message handler into your web applications.

It becomes simpler to operate dependency injection for injecting test data

Spring provides a useful API to translate technology-specific exceptions like as Hibernate, JDBC and JDO.
