struts2结合freemarker
(1)在struts.xml添加跳转:
<package name="loginPackage" extends="jason-default">
<action name="jLogin" class="JLogin">
<result name="success" >/WEB-INF/jason/index.jsp</result>
<result name="error">/WEB-INF/jason/login.jsp</result>
<result name="input">/WEB-INF/jason/login.jsp</result>
<result name="search" type="freemarker">/WEB-INF/templates/jsearch.ftl</result>
<interceptor-ref name="jLoginStack"/>
</action>
</package>
<package name="loginPackage" extends="jason-default">
<action name="jLogin" class="JLogin">
<result name="success" >/WEB-INF/jason/index.jsp</result>
<result name="error">/WEB-INF/jason/login.jsp</result>
<result name="input">/WEB-INF/jason/login.jsp</result>
<result name="search" type="freemarker">/WEB-INF/templates/jsearch.ftl</result>
<interceptor-ref name="jLoginStack"/>
</action>
</package>

在ACTION中,进行设置:
..........
Hits hits = JLuceneUtils.luceneSearch(indexPath, searchMess);
System.out.println("----------hits.length():" + hits.length());
for (int a = 0; a < hits.length(); a++) {
Document doc2 = (Document) hits.doc(a);
System.out.println(searchMess + "的值是:"+ doc2.get("confContext"));
ActionContext.getContext().getSession().put("jsearch_value",

设置模板文件:jsearch.ftl:
<#assign s=JspTaglibs["/WEB-INF/struts-tags.tld"] />
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>jason search result</title>
</head>

<body>
<table width="98%" border="0" align="center" cellpadding="5" cellspacing="0">
<tr>
<td><strong>以面是jason用lucene查询的结果,共有${jsearch_cout}条符合：</strong></td>
</tr>
<tr>
<#-- freemarker插值（如下，是利用EL语言,即将ACTION中的值先放入session/request/application） -->
<td>查询内容：${jsearch_name} --- 查询值：${jsearch_value}</td>
</tr>
<tr>
<td>
<@s.url action="jLogin!login" id="login" />
<a href="${login}">返回登录主页</a>
</td>
</tr>
</table>

如果要使用STRUTS2.0的标签,如上面.就要添加STRUTS2.0的标签库:
web.xml添加:
<servlet>
<servlet-name>JspSupportServlet</servlet-name>
<servlet-class>
org.apache.struts2.views.JspSupportServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
在jsearch.ftl最前面添加:
<#assign s=JspTaglibs["/WEB-INF/struts-tags.tld"] />
