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

 1 public class StudentAction {
 2     private StudentService studentService;
 3     
 4     
 5     public String add(){
 6         System.out.println("StudentAction.add(8888888888888)");
