Method Detail

onStartup

public void onStartup(ServletContext servletContext)
               throws ServletException

Deprecated.

Description copied from interface: WebApplicationInitializer

Configure the given ServletContext with any servlets, filters, listeners context-params and attributes necessary for initializing this web application. See examples above.

Specified by:

onStartup in interface WebApplicationInitializer

Parameters:

servletContext - the ServletContext to initialize

Throws:

ServletException - if any call against the given ServletContext throws a ServletException

registerDispatcherHandler

protected void registerDispatcherHandler(ServletContext servletContext)

Deprecated.

Register a DispatcherHandler against the given servlet context.

This method will create a DispatcherHandler, initializing it with the application context returned from createApplicationContext(). The created handler will be wrapped in a ServletHttpHandlerAdapter servlet with the name returned by getServletName(), mapping it to the pattern returned from getServletMapping().

Further customization can be achieved by overriding customizeRegistration(ServletRegistration.Dynamic) or createDispatcherHandler(ApplicationContext).

Parameters:

servletContext - the context to register the servlet against

getServletName

protected java.lang.String getServletName()

Deprecated.

Return the name under which the ServletHttpHandlerAdapter will be registered. Defaults to DEFAULT_SERVLET_NAME.

See Also:

registerDispatcherHandler(ServletContext)

createApplicationContext

protected abstract ApplicationContext createApplicationContext()

Deprecated.

Create an application context to be provided to the DispatcherHandler.

The returned context is delegated to Spring's DispatcherHandler.DispatcherHandler(ApplicationContext). As such, it typically contains controllers, view resolvers, and other web-related beans.

See Also:

registerDispatcherHandler(ServletContext)

refreshApplicationContext

protected void refreshApplicationContext(ApplicationContext context)

Deprecated.

Refresh the given application context, if necessary.

createDispatcherHandler

protected WebHandler createDispatcherHandler(ApplicationContext applicationContext)

Deprecated.

Create a DispatcherHandler (or other kind of WebHandler-derived dispatcher) with the specified ApplicationContext.

createHandlerAdapter

protected ServletHttpHandlerAdapter createHandlerAdapter(WebHandler webHandler)

Deprecated.

Create a ServletHttpHandlerAdapter.

Default implementation returns a ServletHttpHandlerAdapter with the provided webHandler.

getServletMapping

protected java.lang.String getServletMapping()

Deprecated.

Specify the servlet mapping for the ServletHttpHandlerAdapter.

Default implementation returns /.

See Also:

registerDispatcherHandler(ServletContext)

customizeRegistration

protected void customizeRegistration(ServletRegistration.Dynamic registration)

Deprecated.

Optionally perform further registration customization once registerDispatcherHandler(ServletContext) has completed.

Parameters:

registration - the ServletHttpHandlerAdapter registration to be customized

See Also:

registerDispatcherHandler(ServletContext)

registerCloseListener

protected void registerCloseListener(ServletContext servletContext,
                                     ApplicationContext applicationContext)

Deprecated.

Register a ServletContextListener that closes the given application context when the servlet context is destroyed.

Parameters:

servletContext - the servlet context to listen to

applicationContext - the application context that is to be closed when servletContext is destroyed
