org.springframework.web.context
public interface: WebApplicationContext [javadoc | source]

All Implemented Interfaces:
    ApplicationContext

All Known Implementing Classes:
    AbstractRefreshablePortletApplicationContext, XmlPortletApplicationContext, XmlWebApplicationContext, GenericWebApplicationContext, AbstractRefreshableWebApplicationContext, StaticWebApplicationContext, ConfigurablePortletApplicationContext, StaticPortletApplicationContext, ConfigurableWebApplicationContext

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 a getServletContext method 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 a dispatcher servlet in the MVC framework) has its own child context.

In addition to standard application context lifecycle capabilities, WebApplicationContext implementations need to detect ServletContextAware beans and invoke the setServletContext method accordingly.

Field Summary
 String ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE    Context attribute to bind root WebApplicationContext to on successful startup.

Note: If the startup of the root context fails, this attribute can contain an exception or error as value. Use WebApplicationContextUtils for convenient lookup of the root WebApplicationContext.
