来源：互联网 发布：js 鼠标自动隐藏 编辑：程序博客网 时间：2024/06/05 06:54
这是一个springmvc+hibernate框架整合的demo，拿出来分享，希望对初学框架的人有所帮助；
- 开发前的准备工作
1.所需要的jar包，主要有springmvc jar包，hibernate jar包 ，数据库连接驱动包，数据源jar包，等 ；
具体如下：
- 建立Java web项目
目录结构具体如下：
- 核心配置文件介绍
1.项目核心入口配置文件（web.xml）：

package com.liu.entity;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.Table;import org.hibernate.annotations.GenericGenerator;/** * 此实体的定义应用了springmvc的注解，省去了传统的Hibernate跟数据库之间的映射配置文件 * @author will * */@Entity @Table(name="T_USER") public class User { @Id @GeneratedValue(generator="system-uuid") @GenericGenerator(name = "system-uuid",strategy="uuid") @Column(length=100) private String id; @Column(length=32) private String userName; @Column(length=32) private String age; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } } - 业务逻辑层介绍
1.业务dao层（UserDao.java）：
package com.liu.dao;import java.util.List;import com.liu.entity.User;public interface UserDao {public User getUser(String id); public List<User> getAllUser(); public void addUser(User user); public boolean delUser(String id); public boolean updateUser(User user); }2.业务dao层实现（UserDaoImpl.java）：
package com.liu.daoImpl;import java.util.List;import com.liu.dao.UserDao;import com.liu.entity.User;import org.hibernate.Criteria;import org.hibernate.Query;import org.hibernate.SessionFactory;import org.hibernate.Transaction;public class UserDaoImpl implements UserDao{ private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } /** * 根据用户id查询用户 */ @Override public User getUser(String id) { String hql = "from User u where u.id=?"; Query query = sessionFactory.getCurrentSession().createQuery(hql); query.setString(0, id); return (User)query.uniqueResult(); } /** * 查询所有用户 */ @Override public List<User> getAllUser() { /* String hql = "select * from t_user"; System.out.print("--------------------->");*/ Criteria crit = sessionFactory.getCurrentSession().createCriteria(User.class); System.out.print(crit.list().size()+"--------------------->"); return crit.list(); } /** * 添加用户 */ @Override public void addUser(User user) { System.out.println("用户名：==impl===="+user.getUserName()); System.out.println("用户名：==impl===="+user.getAge()); Transaction tx = sessionFactory.getCurrentSession().beginTransaction(); sessionFactory.getCurrentSession().save(user); tx.commit(); sessionFactory.getCurrentSession().flush(); System.out.println("用户名：==add===="); } /** * 根据用户id删除用户 */ @Override public boolean delUser(String id) { String hql = "delete User u where u.id = ?"; Query query = sessionFactory.getCurrentSession().createQuery(hql); query.setString(0, id); return (query.executeUpdate() > 0); } /** * 编辑用户 */ @Override public boolean updateUser(User user) { String hql = "update User u set u.userName = ?,u.age=? where u.id = ?"; Query query = sessionFactory.getCurrentSession().createQuery(hql); query.setString(0, user.getUserName()); query.setString(1, user.getAge()); query.setString(2, user.getId()); return (query.executeUpdate() > 0); }}- 业务service层实现（UserService.java）
package com.liu.service;import java.util.List;import com.liu.dao.UserDao;import com.liu.daoImpl.UserDaoImpl;import com.liu.entity.User;public class UserService implements UserDao{ private UserDaoImpl userDaoImpl; public UserDaoImpl getUserDaoImpl() { return userDaoImpl; } public void setUserDaoImpl(UserDaoImpl userDaoImpl) { this.userDaoImpl = userDaoImpl; } @Override public User getUser(String id) { return userDaoImpl.getUser(id); } @Override public List<User> getAllUser() { return userDaoImpl.getAllUser(); } @Override public void addUser(User user) { userDaoImpl.addUser(user); } @Override public boolean delUser(String id) { return userDaoImpl.delUser(id); } @Override public boolean updateUser(User user) { return userDaoImpl.updateUser(user); }}- 主要页面介绍
