浅谈struts2、jquery与json的集成
struts2、jquery与json的集成是怎样实现异步交互的，下面我们来做个综合的小案例。
做案例的前提是：先要引入必要的jar包。
比如：
1、struts2-core-2.x.x.x.jar:Struts2框架的核心类库
2、xwork-2.x.x.jar:XWork类库，Struts2在其上构建
3、ognl-2.x.x.jar:对象图导航语言（ObjectGraphNavigationLanguage），struts2框架通过其读写对象的属性
4、freemarker-2.3.x.jar:Struts2的UI标签的模板使用FreeMarker编写
5、commons-logging-1.1.x.jar:ASF出品的日志包，Struts2框架使用这个日志包来支持Log4J和JDK1.4+的日志记录。
6、commons-fileupload-1.2.1.jar文件上传组件，2.1.6版本后必须加入此文件
7、struts2-json-plugin.jarstruts2与json的插件
