Class TilesConfigurer

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

All Implemented Interfaces:

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:

TilesException - in case of cleanup failure
