If you're calling context.getBean() everywhere, you're probably missing the whole point of Spring, which is a dependency injection framework.

In a standalone app, you typically call context.getBean() only once (or at least, very rarely), in order to get a "root" bean. This bean is injected by Spring with other beans, and so on.

In a web app, it all depends on which framework you use. But typically, you register a listener in the web.xml which loads the context for you, and controllers are created and/or injected by Spring.
