Spring is a framework that focuses on many areas than other frameworks do. Testing is very easy here because it follows a ground up to design. And it is a progressing integration technology. This article provides you the benefits of spring while doing a project.
- For organizing the objects in the middle tier effectively, we can make use of this spring framework. This is possible whether we are using EJB or not. In any run time environment and architectural layer, we can make use of the configuration management services of Spring.
- In many projects we can see the proliferation of Singletons. That can be eliminated by Spring.
- Spring use a consistent way in the configuration throughout the projects and applications. Thus it can avoid the use of different custom properties formats. To achieve the simplification Spring make use of Dependency Injection and Invention of Control.
- By decreasing the cost of coding to interfaces, instead of using classes, Spring can provide a better programming practice.
- Spring applications depend on some of its Application Programming Interfaces as possible, because Spring is designed.
- To make a unit testing, for the applications built using Spring, is very easy.
- EJB is not crucial in the application architecture of Spring, but it is considered as an implementation choice. Through local EJBs or POJOs, the business interfaces can be implemented. That will not affect the calling code.
- With out the use of EJB Spring can help us to solve many problems. There is an alternative in Spring for the EJB which is suitable for many application. For example, If we use spring, and only a single database is needed to work, then no need of EJB container and any JTA implementation for the management of declarative transaction. Spring use AOP for that.
- For data accessing a consistent framework is provided by the Spring. These data accessing may be using Hibernate or an implementation with JDO, JDBC or TopLink(product for O/R mapping. Any way the consistency will be there.
- Spring provide this consistency and the simplicity in the programming model, not only in the case of data accessing but in JNDI, JDBC, JavaMail, JMS, in some APIs also. These things makes the Spring an ideal.
Thus Spring do an essential role to reduce the developers complexity by providing a framework which is more sophisticated. And it helps us for implementing the simplest solution.
