Applications of Spring
POJO Based
Spring allows developers to use POJOs to create enterprise-class apps. The advantage of using simply POJOs is that you donβt require an EJB container product like an application server; instead, you may use a powerful servlet container like Tomcat or a commercial product.
Modular
Spring is set up in a modular approach. Even if there are a lot of packages and classes, you only need to worry about the ones you need and ignore the rest.
Integration with existing frameworks
Spring does not reinvent the wheel; rather, it makes extensive use of existing technologies such as numerous ORM frameworks, logging frameworks, JEE, Quartz, and JDK timers, and other view technologies.
Testablity
Because environment-dependent code is put into this framework, testing a Spring-written application is trivial. Furthermore, using JavaBeanstyle POJOs makes it easier to employ dependency injection for injecting test data.
Web MVC
Springβs web framework is a well-designed web MVC framework that is an excellent alternative to web frameworks like Struts and other over-engineered or less popular web frameworks.
Central Exception Handling
Spring provides a handy API for converting technology-specific exceptions (such as those raised by JDBC, Hibernate, or JDO) into consistent, unchecked exceptions.
Lightweight
IoC containers are typically lightweight, especially when compared to EJB containers, for example. This is useful for creating and distributing programmes on systems with limited memory and CPU resources.
