Question

Apache Tiles是否有类似Struts的devMove，它会在每次请求时重新加载tiles.xml文件？如果是这样，如何启用它？

Answer 1

这是另一个使用Listener而不是Filter的工作配置。（自Tiles 2.1.2起）

在web.xml中：

<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>

Answer 2

我使用过瓷砖，但从未试图动态重新加载它。

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

表示：

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

以下在servlet容器中使用tile 2.2.2对我有用。

....
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();

启用Tiles开发模式，如Struts的devMode，以便为每个请求重新加载tiles.xml
