Difference between loading context via DispatcherServlet and ContextLoaderListener

In Spring Web Applications, there are two types of container.

1. Application Context : Initialized by contextloaderlistener or ContextLoaderServlet and defined in web.xml. middle-tier transactional services, data access objects, or other objects that you might want to use (and re-use) across the application. There will be one application context per application.
2. Web Application Context: child context of the application context. web- related components such as controllers and view resolvers.
