整合Struts2.1.6 + Sitemesh2.4.1 + Freemarker 2.3.16
1. 首先 这些jar包都去官方 下载好，包括源代码.
另外还需要struts2-sitemesh-plugin-2.1.6.jar
2. WEB-INF/web.xml 主要设置
评述:这个filter的顺序是有关系的. StrutsPrepareFilter -> FreeMarkerPageFilter -> StrutsExecuteFilter
如果不配置sitemesh-freemarker, freemarker文件就不会被解析.
<!-- SiteMesh FreeMarker -->

<filter-name>struts-prepare</filter-name>

3. WEB-INF/decorators.xml
<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/decorators">
<!-- Any urls that are excluded will never be decorated by Sitemesh -->
<excludes>
<pattern>/exclude.jsp</pattern>
</excludes>
<decorator name="index" page="index.ftl">
<pattern>/*</pattern>
</decorator>
</decorators>
4. WEB-INF/classes/struts.xml 主要配置
<action name="test_*" method="{1}" class="com.starcite.action.TestAction">
<result name="input" type="freemarker">/freemarker/register.ftl</result>
<result name="success" type="freemarker">/freemarker/success.ftl</result>
<result name="error" type="freemarker">/freemarker/error.ftl</result>
</action>
5. com.starcite.action.TestAction.java
package com.starcite.action;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("serial")
public class TestAction extends ActionSupport {
public String input() {
return INPUT;
}
public String error() {
return ERROR;
}
public String success() {
return SUCCESS;
}
}
6. decorators/index.ftl
<html>
<head>
<title>Test - ${title}</title>
${head}
</head>
<body>
<#include "/decorators/header.ftl">
<hr noshade="noshade" size="1"/>
${body}
<hr noshade="noshade" size="1"/>
<#include "/decorators/footer.ftl">
</body>
</html>
7. decorators/header.ftl
自己随便写点东西.
8. decorators/footer.ftl
自己随便写点东西.
9. freemarker/success.ftl
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title><@s.text name="success"/></title>
</head>
<body>
<@s.text name="success.info"/>
</body>
</html>
freemarker/error.ftl, freemarker/register.ftl 略
