Package org.apache.wicket.spring

Class SpringWebApplicationFactory

java.lang.Object

org.apache.wicket.spring.SpringWebApplicationFactory

All Implemented Interfaces:

IWebApplicationFactory

public class SpringWebApplicationFactory
extends Object
implements IWebApplicationFactory

Implementation of IWebApplicationFactory that pulls the WebApplication object out of spring application context. Configuration example:

 <filter>
   <filter-name>MyApplication</filter-name>
   <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
   <init-param>
     <param-name>applicationFactoryClassName</param-name>
     <param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
   </init-param>
 </filter>
 

applicationBean init parameter can be used if there are multiple WebApplications defined on the spring application context. Example:

 <filter>
   <filter-name>MyApplication</filter-name>
   <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
   <init-param>
     <param-name>applicationFactoryClassName</param-name>
     <param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
   </init-param>
   <init-param>
     <param-name>applicationBean</param-name>
     <param-value>phonebookApplication</param-value>
   </init-param>
 </filter>
 

This factory is also capable of creating a WebApplication-specific application context (path to which is specified via the contextConfigLocation filter param) and chaining it to the global one

 <filter>
   <filter-name>MyApplication</filter-name>
   <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
   <init-param>
     <param-name>applicationFactoryClassName</param-name>
     <param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
   </init-param>
   <init-param>
     <param-name>contextConfigLocation</param-name>
     <param-value>classpath:com/myapplication/customers-app/context.xml</param-value>
   </init-param>
 </filter>

Method Detail

getContextConfigLocation

protected final String getContextConfigLocation(WicketFilter filter)

Returns location of context config that will be used to create a WebApplication -specific application context.

Parameters:

filter -

Returns:

location of context config

newApplicationContext

protected org.springframework.web.context.ConfigurableWebApplicationContext newApplicationContext()

Factory method used to create a new instance of the web application context, by default an instance o XmlWebApplicationContext will be created.

Returns:

application context instance

createApplication

public WebApplication createApplication(WicketFilter filter)

Description copied from interface: IWebApplicationFactory

Create application object

Specified by:

createApplication in interface IWebApplicationFactory

Parameters:

filter - the wicket filter

Returns:

application object instance

See Also:

IWebApplicationFactory.createApplication(WicketFilter)

createWebApplicationContext

protected final org.springframework.web.context.ConfigurableWebApplicationContext createWebApplicationContext(org.springframework.web.context.WebApplicationContext parent,
                                                                                                              WicketFilter filter)

Creates and initializes a new WebApplicationContext, with the given context as the parent. Based on the logic in Spring's FrameworkServlet#createWebApplicationContext()

Parameters:

parent - parent application context

filter - wicket filter

Returns:

instance of web application context

Throws:

org.springframework.beans.BeansException

postProcessWebApplicationContext

protected void postProcessWebApplicationContext(org.springframework.web.context.ConfigurableWebApplicationContext wac,
                                                WicketFilter filter)

This is a hook for potential subclasses to perform additional processing on the context. Based on the logic in Spring's FrameworkServlet#postProcessWebApplicationContext()

Parameters:

wac - additional application context

filter - wicket filter

destroy

public void destroy(WicketFilter filter)

Called when the filter instance that used this factory is destroyed

Specified by:

destroy in interface IWebApplicationFactory

Parameters:

filter - the wicket filter
