spring+struts的集成(第一种集成方案)

原理：在Action中取得BeanFactory对象，然后通过BeanFactory获取业务逻辑对象

1、spring和struts依赖库配置

*配置struts

--拷贝struts类库和jstl类库

--修改web.xml文件来配置ActionServlet

--提供struts-config.xml文件

--提供国际化资源文件

*配置spring

--拷贝spring类库

--提供spring配置文件

2、在struts的Action中调用如下代码取得BeanFactory

BeanFactoryfactory=WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext());

3、通过BeanFactory取得业务对象，调用业务逻辑方法
