I want to review the Spring , so begin with a professional acticle in English . Let's see what is Spring
FrameWork，and why we need to work with this spring.
Spring is a light weight and open source framework created by Rod Johnson in 2003. Spring is a complete and
a modular framework, i mean spring framework can be used for all layer implementations for a real time application
or spring can be used for the development of particular layer of a real time application unlike struts [ only for front
end related ] and hibernate [ only for database related ], but with spring we can develop all layers
Spring having this much of demand because of the following 3 reasons….
Spring framework is simple because as it is non-invasive, POJO and POJI model
Actually for writing the spring application, server [Container] is not mandatory, but for struts applications we
need a server, and for EJB too. If we want to test the application it may need lot of changes in the source and each
time we must restart the server to view the changes, which is little tedious and time taking but we can over come this
in Spring, for testing spring application server is not mandatory spring has it own container to run the applications.
Spring can be used to develop any kind of java application, means we can develop starting from console
application to enterprise level application
In spring objects are loosely coupled, this is the core concept of spring framework we will see in depth about
this loose coupling and how its differ from tight coupling.
