在用户请求和模块化处理方面以及页面的展现这块，Struts2 发挥了强大的作用；
相对于传统的Jsp+Servlet 模式，Struts2 更适合企业级团队开发，方便系统的维护；

Action 设置数据
第一种方式：属性驱动(FieldDriven)
A、基本数据类型属性
B、JavaBean 类型属性
第二种方式：模型驱动(ModelDriven)
基本数据类型属性

JavaBean 类型属性

struts.xml 配置
一，pageckage 配置
name 包名
extends 继承
namespace 包命名空间
abstract 抽象包
二，action 配置
name action 名
class 处理类
method 方法
三，分模块配置方法
<include file="" ></include>
