1.web.xml configuration

有三种方式配置Tiles，详细配置见http://tiles.apache.org/tutorial/configuration.html，这里我选择如下配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">
	<display-name>Tiles2</display-name>

	<context-param>
		<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
		<param-value>/WEB-INF/tiles.xml</param-value>
	</context-param>

	<listener>
		<listener-class>org.apache.tiles.web.startup.TilesListener</listener-class>
	</listener>
</web-app>

2.tiles.xml configuration

这里我使用了Tiles Inheritance，可以精简一下代码。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">

<tiles-definitions>
	<definition name="template" template="/WEB-INF/tiles/template.jsp">
		<put-attribute name="header" value="/WEB-INF/tiles/defaultHeader.jsp" />
		<put-attribute name="menu" value="/WEB-INF/tiles/defaultMenu.jsp" />
		<put-attribute name="footer" value="/WEB-INF/tiles/defaultFooter.jsp" />
	</definition>
	
	<definition name="homePage" extends="template">
		<put-attribute name="body" value="/WEB-INF/tiles/home_body.jsp" />
	</definition>
	
	<definition name="aboutPage" extends="template">
		<put-attribute name="body" value="/WEB-INF/tiles/about_body.jsp" />
	</definition>
</tiles-definitions>

3.Project Directory

4.JSP Views

注意，这里主要是为了演示如何使用Apache Tiles，一切从简，所以并没有进行CSS美化，如果要进行CSS美化，可以自行修改，这里不再赘述。

template.jsp

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
	<table border="1" cellspacing="0" cellpadding="0" width="1200dp" align="center">
		<tr height="100dp">
			<td colspan="2"><tiles:insertAttribute name="header" /></td>
		</tr>
		<tr height="500dp">
			<td><tiles:insertAttribute name="menu" /></td>
			<td><tiles:insertAttribute name="body" /></td>
