What is Spring Framework in Java
The one of the most popular frameworks for the purpose of application development in Java enterprise is Spring Framework. This development framework is employed by numerous application developer around the globe as it is easy to use application development framework which has the add on factor of code reusability. Moreover, applications built on this framework is easy to test. It is an open source Java enterprise platform. It was released under the license of Apache 2.0 in June 2003. It is an application development framework written by a programmer named Rod Johnson. Spring framework is known for its transparency and bit size. Hence, it can be said that it is a lightweight framework under Java enterprise. The fundamental version of this Java framework is near about 2MB in size.
The basic visages of this framework can be employed for the purpose of the development of any kind of Java enterprise application. However, there are numerous extensions for developing a web application on the platform of Java EE. The usability of the spring framework of the Java Enterprise lies in its target to make the application development in j2EE an easy approach. I
In addendum, it enables a programming model based on the POJO model for programming approach.
Uses of Spring Framework
Spring Framework makes it an easy task for the developers to build an enterprise level application with the help of using POJOs. Basically, the POJOs eliminates the need of an EJB product container like server for an application. However, the option of employing a powerful container for the servlets like Tomcat or any other commercial development product can be used.
Spring framework is a modularized framework for the application development. In spite of the massive number of the classes and the packages only the required ones have to be taken care of. We can ignore the other unnecessary classes and the packages.
This framework does not invent the wheels again. Instead of that it utilizes the already existing technologies like numerous ORM framework, JEE, logging framework, JDK and Quartz timers and other similar technological platforms.
Testing the web application made up of spring framework is allusively an easy task. The key idea lies behind this is that the code which is dependent on the integrated development environment is moved into spring framework. Moreover, by the usage of POJOs like JavaBeanStyle it becomes a cinch to injecting the test database by using the dependency injection for the dataset.
Spring framework offers a consistent interface for the purpose of transaction management which can be scaled down for the purpose of local data transaction.
