Class ComponentControllerSupport

java.lang.Object

ControllerSupport

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

Deprecated.

as of Spring 3.0

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

Modifier and Type	Method and Description
protected abstract void	doPerform(ComponentContext componentContext, HttpServletRequest request, HttpServletResponse response) Deprecated. Perform the preparation for the component, allowing for any Exception to be thrown.
void	execute(ComponentContext componentContext, HttpServletRequest request, HttpServletResponse response, 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 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(ComponentContext componentContext, HttpServletRequest request, HttpServletResponse response, ServletContext servletContext) Deprecated. This implementation delegates to execute, converting non-Servlet/IO Exceptions to ServletException.

Method Detail

perform

public final void perform(ComponentContext componentContext,
                          HttpServletRequest request,
                          HttpServletResponse response,
                          ServletContext servletContext)
                   throws 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.

Throws:

ServletException

java.io.IOException

execute(ComponentContext, HttpServletRequest, HttpServletResponse, ServletContext)

execute

public final void execute(ComponentContext componentContext,
                          HttpServletRequest request,
                          HttpServletResponse response,
                          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.

Throws:

java.lang.Exception

See Also:

perform(ComponentContext, HttpServletRequest, HttpServletResponse, ServletContext), doPerform(ComponentContext, HttpServletRequest, 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 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(ComponentContext componentContext,
                                  HttpServletRequest request,
                                  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
