Method Detail

getWebServer

public WebServer getWebServer(ServletContextInitializer... initializers)

Description copied from interface: ServletWebServerFactory

Gets a new fully configured but paused WebServer instance. Clients should not be able to connect to the returned server until WebServer.start() is called (which happens when the ApplicationContext has been fully refreshed).

Specified by:

getWebServer in interface ServletWebServerFactory

Parameters:

initializers - ServletContextInitializers that should be applied as the server starts

Returns:

a fully configured and started WebServer

See Also:

WebServer.stop()

configureWebAppContext

protected final void configureWebAppContext(WebAppContext context,
                                            ServletContextInitializer... initializers)

Configure the given Jetty WebAppContext for use.

Parameters:

context - the context to configure

initializers - the set of initializers to apply

addDefaultServlet

protected final void addDefaultServlet(WebAppContext context)

Add Jetty's DefaultServlet to the given WebAppContext.

Parameters:

context - the jetty WebAppContext

addJspServlet

protected final void addJspServlet(WebAppContext context)

Add Jetty's JspServlet to the given WebAppContext.

Parameters:

context - the jetty WebAppContext

getWebAppContextConfigurations

protected Configuration[] getWebAppContextConfigurations(WebAppContext webAppContext,
                                                         ServletContextInitializer... initializers)
