The Spring IoC container is at the core of the Spring Framework. The container will create the objects, wire them together, configure them, and manage their complete life cycle from creation till destruction. The Spring container uses dependency injection (DI) to manage the components that make up an application.
Spring provides following two distinct types of containers.
BeanFactory container
ApplicationContext container
A BeanFactory is essentially nothing more than the interface for an advanced factory capable of maintaining a registry of different beans and their dependencies. The BeanFactory enables you to read bean definitions and access them using the bean factory.
ApplicationContext container adds more enterprise-specific functionality such as the ability to resolve textual messages from a properties file and the ability to publish application events to interested event listeners. This container is defined by the org.springframework.context.ApplicationContext interface.
The ApplicationContext container includes all functionality of the BeanFactory container, so it is generally recommended over the BeanFactory. BeanFactory can still be used for lightweight applications like mobile devices or applet based applications where data volume and speed is significant.
The most commonly used ApplicationContext implementations are:
FileSystemXmlApplicationContext
ClassPathXmlApplicationContext
WebXmlApplicationContext
