啓用Tiles devMode，如Struts的devMode，以便隨每個請求重新加載tiles.xml

Question

Apache Tiles是否具有像Struts一樣的devMove，可以爲每個請求重新加載tiles.xml文件？如果是這樣，那麼如何啓用？

Answer 1

我已經使用了瓷磚，但從未試圖動態地重新加載它。

但是，此頁：http://tiles.apache.org/tutorial/configuration.html

說：

Load the Tiles filter. It is useful if your definition files can be changed and you periodically need to reload them. 

Answer 2

下面是一個使用的，而不是過濾器監聽另一個工作配置。 （因爲瓷磚2.1.2）

在web.xml：

<context-param> 
    <param-name>org.apache.tiles.definition.dao.LocaleUrlDefinitionDAO.CHECK_REFRESH</param-name> 
    <param-value>true</param-value> 
</context-param> 
<listener> 
    <listener-class>org.apache.tiles.web.startup.TilesListener</listener-class> 
</listener>

下一直逼着我用servlet容器內瓦2.2.2。

.... 
import org.apache.tiles.definition.DefinitionsFactory; 
import org.apache.tiles.definition.UnresolvingLocaleDefinitionsFactory; 
import org.apache.tiles.definition.dao.ResolvingLocaleUrlDefinitionDAO; 
import org.apache.tiles.impl.BasicTilesContainer; 
import org.apache.tiles.servlet.context.ServletUtil; 

//When using SimpleTilesListener => BasicTilesContainer is returned 
//When using StrutsTilesListener => CachingTilesContainer is returned which extends BasicTilesContainer 
BasicTilesContainer tilesCont = (BasicTilesContainer) ServletUtil.getContainer(ServletActionContext.getServletContext()); 

DefinitionsFactory defFact = tilesCont.getDefinitionsFactory(); 
Field field= UnresolvingLocaleDefinitionsFactory.class.getDeclaredField("definitionDao"); 
field.setAccessible(true); 
ResolvingLocaleUrlDefinitionDAO rludDAO = (ResolvingLocaleUrlDefinitionDAO)field.get(defFact); 
rludDAO.refresh();
