重新学习之spring第四个程序,整合struts2+hibernate+spring
第一步:导入三大框架的jar包(struts2.3.16.1+hibernate3.2+spring3.2.4)
第二步:编写web.xml 和struts.xml和applicationContext.xml和applicationContext-service.xml和application-actionContext.xml和applicationContext-dao.xml
web.xml

添加一个用户
访问localhost:8080/Struts2HibernateSpring/StudentAction!add向数据库中的表添加一个用户
StudenAction省去setget方法
