org.springframework.web.servlet.view.tiles
Class ComponentControllerSupport

java.lang.Object
  extended by org.apache.struts.tiles.ControllerSupport
      extended by org.springframework.web.servlet.view.tiles.ComponentControllerSupport
All Implemented Interfaces:
org.apache.struts.tiles.Controller

Deprecated. as of Spring 3.0

@Deprecated
public abstract class ComponentControllerSupport
extends org.apache.struts.tiles.ControllerSupport

Convenience class for Spring-aware Tiles component controllers. Provides a reference to the current Spring application context, e.g. for bean lookup or resource loading.

Derives from the Tiles ControllerSupport class rather than implementing the Tiles Controller interface in order to be compatible with Struts 1.1 and 1.2. Implements both Struts 1.1's perform and Struts 1.2's execute method accordingly.

Method Summary
protected abstract  void doPerform(org.apache.struts.tiles.ComponentContext componentContext, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response)
          Deprecated. Perform the preparation for the component, allowing for any Exception to be thrown.
 void execute(org.apache.struts.tiles.ComponentContext componentContext, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response, javax.servlet.ServletContext servletContext)
          Deprecated. This implementation delegates to doPerform, lazy-initializing the application context reference if necessary.
protected  ApplicationContext getApplicationContext()
          Deprecated. Return the current Spring ApplicationContext.
protected  MessageSourceAccessor getMessageSourceAccessor()
          Deprecated. Return a MessageSourceAccessor for the application context used by this object, for easy message access.
protected  javax.servlet.ServletContext getServletContext()
          Deprecated. Return the current ServletContext.
protected  java.io.File getTempDir()
          Deprecated. Return the temporary directory for the current web application, as provided by the servlet container.
protected  WebApplicationContext getWebApplicationContext()
          Deprecated. Return the current Spring WebApplicationContext.
protected  void initApplicationContext()
          Deprecated. Subclasses can override this for custom initialization behavior.
 void perform(org.apache.struts.tiles.ComponentContext componentContext, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response, javax.servlet.ServletContext servletContext)

Method Detail

perform

public final void perform(org.apache.struts.tiles.ComponentContext componentContext,
                          javax.servlet.http.HttpServletRequest request,
                          javax.servlet.http.HttpServletResponse response,
                          javax.servlet.ServletContext servletContext)
                   throws javax.servlet.ServletException,
                          java.io.IOException
Deprecated. 
This implementation delegates to execute, converting non-Servlet/IO Exceptions to ServletException.

This is the only execution method available in Struts 1.1.

Specified by:
perform in interface org.apache.struts.tiles.Controller
Overrides:
perform in class org.apache.struts.tiles.ControllerSupport
Throws:
javax.servlet.ServletException
java.io.IOException
See Also:
execute(org.apache.struts.tiles.ComponentContext, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.ServletContext)

execute

public final void execute(org.apache.struts.tiles.ComponentContext componentContext,
                          javax.servlet.http.HttpServletRequest request,
                          javax.servlet.http.HttpServletResponse response,
                          javax.servlet.ServletContext servletContext)
                   throws java.lang.Exception
Deprecated. 
This implementation delegates to doPerform, lazy-initializing the application context reference if necessary.

This is the preferred execution method in Struts 1.2. When running with Struts 1.1, it will be called by perform.

Specified by:
execute in interface org.apache.struts.tiles.Controller
Overrides:
execute in class org.apache.struts.tiles.ControllerSupport
Throws:
java.lang.Exception
See Also:
perform(org.apache.struts.tiles.ComponentContext, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.ServletContext), doPerform(org.apache.struts.tiles.ComponentContext, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

initApplicationContext

protected void initApplicationContext()
                               throws BeansException
Deprecated. 
Subclasses can override this for custom initialization behavior. Gets called on initialization of the context for this controller.

Throws:
ApplicationContextException - in case of initialization errors
BeansException - if thrown by application context methods

getApplicationContext

protected final ApplicationContext getApplicationContext()
Deprecated. 
Return the current Spring ApplicationContext.


getWebApplicationContext

protected final WebApplicationContext getWebApplicationContext()
Deprecated. 
Return the current Spring WebApplicationContext.


getMessageSourceAccessor

protected final MessageSourceAccessor getMessageSourceAccessor()
Deprecated. 
Return a MessageSourceAccessor for the application context used by this object, for easy message access.


getServletContext

protected final javax.servlet.ServletContext getServletContext()
Deprecated. 
Return the current ServletContext.


getTempDir

protected final java.io.File getTempDir()
Deprecated. 
Return the temporary directory for the current web application, as provided by the servlet container.

Returns:
the File representing the temporary directory

doPerform

protected abstract void doPerform(org.apache.struts.tiles.ComponentContext componentContext,
                                  javax.servlet.http.HttpServletRequest request,
                                  javax.servlet.http.HttpServletResponse response)
                           throws java.lang.Exception
Deprecated. 
Perform the preparation for the component, allowing for any Exception to be thrown. The ServletContext can be retrieved via getServletContext, if necessary. The Spring WebApplicationContext can be accessed via getWebApplicationContext.

This method will be called both in the Struts 1.1 and Struts 1.2 case, by perform or execute, respectively.

Parameters:
componentContext - current Tiles component context
request - current HTTP request
response - current HTTP response
Throws:
java.lang.Exception - in case of errors
