public abstract class AbstractRefreshableWebApplicationContext
extends org.springframework.context.support.AbstractRefreshableConfigApplicationContext
implements ConfigurableWebApplicationContext, org.springframework.ui.context.ThemeSource

AbstractRefreshableApplicationContext subclass which implements the ConfigurableWebApplicationContext interface for web environments. Provides a "configLocations" property, to be populated through the ConfigurableWebApplicationContext interface on web application startup.

This class is as easy to subclass as AbstractRefreshableApplicationContext: All you need to implements is the AbstractRefreshableApplicationContext.loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory) method; see the superclass javadoc for details. Note that implementations are supposed to load bean definitions from the files specified by the locations returned by the getConfigLocations() method.

Interprets resource paths as servlet context resources, i.e. as paths beneath the web application root. Absolute paths, e.g. for files outside the web app root, can be accessed via "file:" URLs, as implemented by DefaultResourceLoader.

In addition to the special beans detected by AbstractApplicationContext, this class detects a bean of type ThemeSource in the context, under the special bean name "themeSource".

This is the web context to be subclassed for a different bean definition format. Such a context implementation can be specified as "contextClass" context-param for ContextLoader or as "contextClass" init-param for org.springframework.web.servlet.FrameworkServlet, replacing the default XmlWebApplicationContext. It will then automatically receive the "contextConfigLocation" context-param or init-param, respectively.

Note that WebApplicationContext implementations are generally supposed to configure themselves based on the configuration received through the ConfigurableWebApplicationContext interface. In contrast, a standalone application context might allow for configuration in custom startup code (for example, GenericApplicationContext).

Method Detail

public void setServletContext(ServletContext servletContext)

Description copied from interface: ConfigurableWebApplicationContext

Set the ServletContext for this web application context.

Does not cause an initialization of the context: refresh needs to be called after the setting of all configuration properties.

Specified by:

setServletContext in interface ConfigurableWebApplicationContext

See Also:

ConfigurableApplicationContext.refresh()

getServletContext

public ServletContext getServletContext()

Description copied from interface: WebApplicationContext

Return the standard Servlet API ServletContext for this application.
