package cn.scau.ssh2.dao;import java.util.List;import cn.scau.ssh2.beans.User;public interface UserDao {public void saveUser(User user);public void removeUser(User user);public User findUserById(int id);public List<User> findAllUserser();public void updateUser(User user);}7.建立cn.scau.ssh2.dao.impl包包下有UserDaoImpl.java为具体的实现：package cn.scau.ssh2.dao.impl;import java.util.List;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import cn.scau.ssh2.beans.User;import cn.scau.ssh2.dao.UserDao;//继承HibernateDaoSupport，用到了getHibernateTemplate这个方法。public class UserDaoImpl extends HibernateDaoSupport implements UserDao {@SuppressWarnings("unchecked")public List<User> findAllUserser() {String hql = "from User user order by user.id desc";List<User> list = this.getHibernateTemplate().find(hql);return list;}public User findUserById(int id) {User user = (User) this.getHibernateTemplate().get(User.class, id);return user;}public void removeUser(User user) {this.getHibernateTemplate().delete(user);}public void saveUser(User user) {this.getHibernateTemplate().save(user);}public void updateUser(User user) {this.getHibernateTemplate().update(user);}}

8. 建立cn.scau.ssh2.service包

package cn.scau.ssh2.action;import java.util.Iterator;import java.util.Map;import java.util.Set;import cn.scau.ssh2.beans.User;import cn.scau.ssh2.service.UserService;import com.opensymphony.xwork2.ActionSupport;public class SaveUserAction extends ActionSupport {private static final long serialVersionUID = -4055521880257114396L;private User user;private UserService userService;//get方法可以不用写，因为要用到的只是set方法public UserService getUserService() {return userService;}public void setUserService(UserService userService) {this.userService = userService;}public void setUser(User user) {this.user = user;}public User getUser() {return user;}@Overridepublic String execute() throws Exception {this.userService.save(user);return SUCCESS;}}
