com.opensymphony.module.sitemesh.filter.PageFilter 装饰页面

1、web.xml中配置：

<filter>
        <filter-name>sitemeshFilter</filter-name>
        <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>sitemeshFilter</filter-name>
        <url-pattern>/a/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>sitemeshFilter</filter-name>
        <url-pattern>/f/*</url-pattern>
    </filter-mapping>

2、并列web.xml新建文件decorators.xml：

<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/WEB-INF/views">
    
    <!-- 默认装饰页面, 在需要装饰的页面增加<meta name="decorator" content="default"/> -->
    <decorator name="blank" page="layouts/blank.jsp" />
    <decorator name="default" page="layouts/default.jsp" />
    
</decorators>

3、在需要装饰的页面增加<meta name="decorator" content="default"/>

相当于占位符；

4、default.jsp内容：

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/WEB-INF/views/include/taglib.jsp"%>
<%@ taglib prefix="sitemesh" uri="http://www.opensymphony.com/sitemesh/decorator" %>
<!DOCTYPE html>
<html style="overflow-x:auto;overflow-y:auto;">
<head>
	<title><sitemesh:title/></title>
	<%@include file="/WEB-INF/views/include/head.jsp" %>		
	<!-- Baidu tongji analytics --><script>var _hmt=_hmt||[];(function(){var hm=document.createElement("script");hm.src="//hm.baidu.com/hm.js?82116c626a8d504a5c0675073362ef6f";var s=document.getElementsByTagName("script")[0];s.parentNode.insertBefore(hm,s);})();</script>
	<sitemesh:head/>
</head>
<body>
	<sitemesh:body/>
	  <script type="text/javascript">//<!-- 无框架时，左上角显示菜单图标按钮。
		if(!(self.frameElement && self.frameElement.tagName=="IFRAME")){
			//$("body").prepend("<i id="btnMenu" class="icon-th-list" style="cursor:pointer;float:right;margin:10px;"></i><div id="menuContent"></div>");
			//$("#btnMenu").click(function(){
				//top.$.jBox('get:${ctx}/sys/menu/treeselect;JSESSIONID=<shiro:principal property="sessionid"/>', {title:'选择菜单', buttons:{'关闭':true}, 300, height: 350, top:10});
				//if ($("#menuContent").html()==""){$.get("${ctx}/sys/menu/treeselect", function(data){$("#menuContent").html(data);});}else{$("#menuContent").toggle(100);}
			//});
		}//-->
	</script>  
</body>
</html>
