## Class TilesConfigurer

- java.lang.Object
- - org.springframework.web.servlet.view.tiles2.TilesConfigurer

- All Implemented Interfaces:
    Aware, DisposableBean, InitializingBean, ServletContextAware

      public class TilesConfigurer
      extends Object
      implements ServletContextAware, InitializingBean, DisposableBean

  Helper class to configure Tiles 2.x for the Spring Framework. See http://tiles.apache.org for more information about Tiles, which basically is a templating mechanism for JSP-based web applications. Note: Spring 3.0 requires Tiles 2.1.2 or above, with explicit support for Tiles 2.2. Tiles 2.1's EL support will be activated by default when running on JSP 2.1 or above and when the Tiles EL module is present in the classpath.

  The TilesConfigurer simply configures a TilesContainer using a set of files containing definitions, to be accessed by `TilesView` instances. This is a Spring-based alternative (for usage in Spring configuration) to the Tiles-provided `TilesListener` (for usage in `web.xml`).

  TilesViews can be managed by any `ViewResolver`. For simple convention-based view resolution, consider using `TilesViewResolver`.

  A typical TilesConfigurer bean definition looks as follows:

       <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
         <property name="definitions">
           <list>
             <value>/WEB-INF/defs/general.xml</value>
             <value>/WEB-INF/defs/widgets.xml</value>
             <value>/WEB-INF/defs/administrator.xml</value>
             <value>/WEB-INF/defs/customer.xml</value>
             <value>/WEB-INF/defs/templates.xml</value>
           </list>
         </property>
       </bean>

  The values in the list are the actual Tiles XML files containing the definitions.

  - ### Method Detail

    - #### setTilesInitializer

          public void setTilesInitializer(TilesInitializer tilesInitializer)

      Configure Tiles using a custom TilesInitializer, typically specified as an inner bean.

      Default is a variant of `DefaultTilesInitializer`, respecting the "definitions", "preparerFactoryClass" etc properties on this configurer.

      NOTE: Specifying a custom TilesInitializer effectively disables all other bean properties on this configurer. The entire initialization procedure is then left to the TilesInitializer as specified.

    - #### setCompleteAutoload

          public void setCompleteAutoload(boolean completeAutoload)

      Specify whether to apply Tiles 2.2's "complete-autoload" configuration.

      See `CompleteAutoloadTilesContainerFactory` for details on the complete-autoload mode.

      NOTE: Specifying the complete-autoload mode effectively disables all other bean properties on this configurer. The entire initialization procedure is then left to `CompleteAutoloadTilesInitializer`.

      See Also:
        `CompleteAutoloadTilesContainerFactory`, `CompleteAutoloadTilesInitializer`

    - #### setDefinitions

          public void setDefinitions(String[] definitions)

      Set the Tiles definitions, i.e. the list of files containing the definitions. Default is "/WEB-INF/tiles.xml".

    - #### setCheckRefresh

          public void setCheckRefresh(boolean checkRefresh)

      Set whether to check Tiles definition files for a refresh at runtime. Default is "false".

    - #### setValidateDefinitions

          public void setValidateDefinitions(boolean validateDefinitions)

      Set whether to validate the Tiles XML definitions. Default is "true".

    - #### setDefinitionsFactoryClass

          public void setDefinitionsFactoryClass(Class<? extends DefinitionsFactory> definitionsFactoryClass)

      Set the `DefinitionsFactory` implementation to use. Default is `UrlDefinitionsFactory`, operating on definition resource URLs.

      Specify a custom DefinitionsFactory, e.g. a UrlDefinitionsFactory subclass, to customize the creation of Tiles Definition objects. Note that such a DefinitionsFactory has to be able to handle `URL` source objects, unless you configure a different TilesContainerFactory.

    - #### setPreparerFactoryClass

          public void setPreparerFactoryClass(Class<? extends PreparerFactory> preparerFactoryClass)

      Set the `PreparerFactory` implementation to use. Default is `BasicPreparerFactory`, creating shared instances for specified preparer classes.

      Specify `SimpleSpringPreparerFactory` to autowire `ViewPreparer` instances based on specified preparer classes, applying Spring's container callbacks as well as applying configured Spring BeanPostProcessors. If Spring's context-wide annotation-config has been activated, annotations in ViewPreparer classes will be automatically detected and applied.

      Specify `SpringBeanPreparerFactory` to operate on specified preparer names instead of classes, obtaining the corresponding Spring bean from the DispatcherServlet's application context. The full bean creation process will be in the control of the Spring application context in this case, allowing for the use of scoped beans etc. Note that you need to define one Spring bean definition per preparer name (as used in your Tiles definitions).

        `SimpleSpringPreparerFactory`, `SpringBeanPreparerFactory`

    - #### setUseMutableTilesContainer

          public void setUseMutableTilesContainer(boolean useMutableTilesContainer)

      Set whether to use a MutableTilesContainer (typically the CachingTilesContainer implementation) for this application. Default is "false".
      See Also:
        `MutableTilesContainer`, `CachingTilesContainer`

    - #### setTilesProperties

          public void setTilesProperties(Properties tilesProperties)

      Set Tiles properties (equivalent to the ServletContext init-params in the Tiles documentation), overriding the default settings.

      NOTE: This property is only effective with Tiles 2.1. Tiles 2.2 doesn't support property-based configuration anymore.

    - #### setServletContext

          public void setServletContext(ServletContext servletContext)

      Description copied from interface: `ServletContextAware`
      Set the `ServletContext` that this object runs in.

      Invoked after population of normal bean properties but before an init callback like InitializingBean's `afterPropertiesSet` or a custom init-method. Invoked after ApplicationContextAware's `setApplicationContext`.

      Specified by:
        `setServletContext` in interface `ServletContextAware`
      Parameters:
        `servletContext` - ServletContext object to be used by this object

        `InitializingBean.afterPropertiesSet()`, `ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext)`

    - #### afterPropertiesSet

          public void afterPropertiesSet()
                                  throws TilesException

      Creates and exposes a TilesContainer for this web application, delegating to the TilesInitializer.
      Specified by:
        `afterPropertiesSet` in interface `InitializingBean`
      Throws:
        `TilesException` - in case of setup failure
      See Also:
        `createTilesInitializer()`

    - #### createTilesInitializer

          protected TilesInitializer createTilesInitializer()

      Creates a new instance of `BasicTilesInitializer`.

      Override it to use a different initializer.

        `TilesListener`

    - #### destroy

          public void destroy()
                       throws TilesException

      Removes the TilesContainer from this web application.
      Specified by:
        `destroy` in interface `DisposableBean`
      Throws:
