## Class ComponentControllerSupport

- java.lang.Object
- - org.apache.struts.tiles.ControllerSupport
  - - 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.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected abstract void` | `doPerform(org.apache.struts.tiles.ComponentContext componentContext, HttpServletRequest request, HttpServletResponse response)` Deprecated. Perform the preparation for the component, allowing for any Exception to be thrown.
    `void` | `execute(org.apache.struts.tiles.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 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, 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(org.apache.struts.tiles.ComponentContext componentContext,
                     HttpServletRequest request,
                     HttpServletResponse response,
                     ServletContext servletContext)
                             throws ServletException,
                                    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:
        `ServletException`
        `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,
                     HttpServletRequest request,
                     HttpServletResponse response,
                     ServletContext servletContext)
                             throws 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:
        `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 ServletContext getServletContext()

      Deprecated.
      Return the current ServletContext.

    - #### getTempDir

          protected final 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,
                       HttpServletRequest request,
                       HttpServletResponse response)
                                     throws 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:
        `Exception` - in case of errors
