一个简单的基于Struts2+Spring+Hibernate+MySql的注册登录系统

package com.cs.action; import com.cs.dao.UserDao; import com.cs.model.User; public class UserAction { private UserDao userDao ; private User user ; public User getUser() { return user; } public void setUser(User user) { this.user = user; } public String execute(){ System.out.println("=======execute================"); System.out.println(user.getFirstname() +" "+user.getLastname()); return "success" ; } public String save(){ System.out.println(user.getFirstname() +" "+user.getLastname()); System.out.println("=======save================"); userDao.saveUser(user) ; return "success" ; } public String update(){ System.out.println("=======update================"); User user = this.userDao.findUser(1) ; user.setAge(18) ; userDao.updateUser(user) ; return "update" ; } public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; } }
