Struts2 与 freemarker 生成Json、XML 的模板

Xml代码

1. ///struts.xml 
2. <struts>
3. <include file="struts-default.xml"/>
4. <package name="json" extends="json-default">
5. <action name="extjs" class="book.action.ExtjsAction">
6. <result type="json"/><!-- 这里生成Json -->
7. </action>
8. <action name="extjsXml" class="book.action.ExtjsAction">
9. <result type="freemarker">
10. <param name="location">template/gridXml.ftl</param>
11. <param name="contentType">application/xml</param>
12. </result>
13. </action>
14. </package>
15. </struts>
