AJAX

freemarker Dojo Struts Ajax jQuery

前几天开始学习struts2，打算用struts2+sitemesh+freemarker+ Spring+ ibatis做一个简单系统。
开发过程中突然想加入ajax技术，看到struts2已经包含了Dojo。于是便开始尝试加入ajax。根据《struts2权威指南》和网上的参考，终于弄好了siteMesh+freemarker。但是当在某个页面加入dojo的时候，发现局部刷新的内容包含了整个template的内容，即ajax 结果页面仍旧被siteMesh+freemarker所截取。后来仔细与struts2 showcase比较，最终发现自己少了一个配置文件sitemesh.xml,现在终于可以了。
特记录如下：
web.xml:

<div id="footer">
<#include "/WEB-INF/decorators/footer.ftl">
</div>
</div>
<script> jQuery("#loader_container").hide();</script>
     </body>
</html>

其中header.ftl、menu.ftl、footer.ftl都很简单

同时需要在decorator.xml中排除不需要装饰的页面，即ajax关联的页面或action

<?xml version="1.0" encoding="UTF-8"?>

<decorators defaultdir="/WEB-INF/decorators">
     <excludes>
     <pattern>/login.jsp</pattern>
     <pattern>/welcome.jsp</pattern>
     <pattern>/pages/test/*</pattern>
     <pattern>/upload/*</pattern>
     <pattern>/pages/ajax/AjaxResult*</pattern>
     <pattern>/pages/test/*</pattern>
     <pattern>/AjaxTest.action</pattern>
     </excludes>


    <decorator name="main" page="template.ftl">

        <pattern>/*</pattern>
    </decorator>
</decorators>
