Interface WebApplicationContext

All Superinterfaces:

ApplicationContext, BeanFactory, ListableBeanFactory, MessageSource, ThemeSource

All Known Implementing Classes:

XmlWebApplicationContext, StaticWebApplicationContext

public interface WebApplicationContext

extends ApplicationContext, ThemeSource

Interface to provide configuration for a web application. This is read-only while the application is running, but may be reloaded if the implementation supports this.

This interface adds ServletContext methods to the generic ApplicationContext interface, and defines a well-known application attribute name that the root context must be bound to in the bootstrap process.

Like generic application contexts, web application contexts are hierarchical. There is a single root context per application, while each servlet in the application (including controller servlets in the MVC framework) has its own child context.
