SiteMesh, SpringMVC, Shiro 配置
1. 首先在在web.xml文件中，加入SiteMesh和shiro的过滤器，保证SiteMesh的过滤器配置放在shiro的过滤器后面，不然的话，shiro的标签不能正确处理。

</session-config>
</web-app>
2. pom.xml中引入sitemesh的依赖
<dependency>
<groupId>org.sitemesh</groupId>
<artifactId>sitemesh</artifactId>
<version>3.0.1</version>
</dependency>
3. 在WEB-INF下加入sitemesh的配置文件(sitemesh3.xml)：
<?xml version="1.0" encoding="UTF-8"?>
<sitemesh>
<!-- Map default decorator. This shall be applied to all paths if no other paths match. -->
<mapping path="/*" decorator="/main.jsp" exclude="false" /> <!-- Exclude path from decoration. -->
<mapping path="/js/*" exclude="true" />
<mapping path="/img/*" exclude="true" />
<mapping path="/images/*" exclude="true" />
<mapping path="/css/*" exclude="true" />
<mapping path="/font-awesome/*" exclude="true" />
<mapping path="/login" exclude="true" />
<mapping path="/login.jsp" exclude="true" />
</sitemesh>
main.jsp 为模板页面，<mapping exlude /> 表示不经过sitemesh处理的资源和页面。
4. 模板页面的书写
在模板页面中可以使用下面的标签作为占位符：
<sitemesh:write property='title' />
<sitemesh:write property='head' />
<sitemesh:write property='body' />
被装饰的页面，可以使用自己页面中的对应部分（title, head, body），填充在这些标签的位置。
下面看一个模板页面的例子：
<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
<%@ taglib prefix="s" uri="http://www.springframework.org/tags" %>
<!DOCTYPE html>
<html>
<head>
<title><sitemesh:write property='title' /></title>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

}
</style>
<sitemesh:write property='head' />
</head>
<body> <!--Header-part-->
<div id="header">

</ul>
</div>
<!--sidebar-menu--> <!--main-container-part-->
<sitemesh:write property='body' /> <!-- end-Footer-part -->
</body>
</html>
上面的模板页面使用了：<sitemesh:write property='title' />， <sitemesh:write property='head' />，<sitemesh:write property='body' />
然后我们看下被装饰的页面：
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>

</script>
</body>
</html>
我们看到被装饰页面的整个 body 部分，会填充到装饰页面中的 <sitemesh:write property='body' /> 处。
正好是注释： <!--main-container-part--> 和 <!-- end-Footer-part --> 相匹配和对应。
注意：模板页面的 <sitemesh:write property='head' /> 最好放置head标签的最后面，因为被装饰页面中的head部分由可能存在依赖于模板页面中的js库。
我们看到sitemesh的使用还是十分简单的。
