今天在做个整合时，决定用sitemesh把几个页面的布局整理下。
很久没使用过了，咋一用还出了不少问题，幸亏网上资料比较多。所以还算比较顺利的解决了。
总结一下
我的版本是struts2 2.1.8
1、struts2 中使用sitemesh一定要用struts2 的插件 struts2-sitemesh-plugin-****.jar
否则是没有效果的
2、在web.xml中的filter顺序
<filter>
<filter-name>struts-cleanup</filter-name>
<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
</filter>
<filter-mapping>
<filter-name>struts-cleanup</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,struts-plugin.xml,struts.xml,struts-tica.xml</param-value>
</init-param>
</filter>
sitemesh的filter一定是在
ActionContextCleanUp 和 StrutsPrepareAndExecuteFilter
之间的，千万别放错了，否则一定出问题
3、上述的弄完之后，可以建立你的模版文件了，下面，我都用自己的页面来举例了
/decorators/basic-theme.jsp
<%@page contentType="text/html; charset=UTF-8"%>
<%@ page pageEncoding="UTF-8" %>
<%@page import="com.qeweb.framework.common.Envir"%>
<%@page import="com.qeweb.tica.vendormgt.action.RegistAC"%>
<%@ taglib uri="http://www.opensymphony.com/sitemesh/decorator" prefix="decorator" %>
<%@ include file="/WEB-INF/tica/common/jsp_includes.jsp"%>
<%
response.setHeader("Cache-Control", "no-cache"); //HTTP 1.1
response.setHeader("Pragma", "no-cache"); //HTTP 1.0
response.setDateHeader("Expires", 0);
%>
<% String wwwroot = request.getContextPath();%>
<html>
<head>
<decorator:head></decorator:head>
</head>
<body>
<body style="width: 100%;margin: 0 auto;" >
<center>
<div>
<DIV class="topArc" style="height: 80px;"><img src="<%=ctx %>/framework/images/preference/theme/logo/<%=DisplayType.getThemeType() %>.jpg" width="100%" height="100%"></DIV>
<div id="rbody" class="wrap">
<div class="title">
<h1></h1>
</div>
<decorator:body></decorator:body>
</div>
</div>
</center>
<center>
<font size="2" color="#555555"></font>
</center>
</body>
</html>
4、装饰配置文件
/WEB-INF/decorators.xml
<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/decorators">
<excludes>
<pattern>*.js</pattern>
<pattern>*.gif</pattern>
<pattern>*.jpg</pattern>
<pattern>*.png</pattern>
<pattern>*.css</pattern>
</excludes>
<decorator name="basic-theme" page="basic-theme.jsp">
<pattern>/ticavendor/regist*.action</pattern>
</decorator>
</decorators>
至此，最简单的一个sitemesh装配就完成了
