工具：myeclipse9.0

Spring版本：2.5.6

Hibernate版本：3

昨天花了一下午時間把Spring和Hibernate整合到了一起，今天做一個筆記。 ?

首先建立java Project工程

點擊Finish完成

添加Hibernate和Spring所需要的jar包還有Mysql連接的jar包

創建Dao層，Dao層實現，Model層，Service層

DAO層代碼：IUserDao

[java] view plain copy

package?org.zhy.demo.dao;??

??

import?java.sql.SQLException;??

??

import?org.zhy.demo.dao.model.UserInfo;??

/**?

?*?DAO層簡單的增刪改查方法?

?*?@author?Administrator?

?*?

?*/??

public?interface?IUserDao?{??

??

????public?void?saveUser(UserInfo?user)?throws?SQLException;??

??

????public?void?delUser(UserInfo?user)?throws?SQLException;??

??

????public?void?editUsre(UserInfo?user)?throws?SQLException;??

??

????public?UserInfo?getUserById(int?id)?throws?SQLException;??

??

}??

IUuserDao層實現（暫時空實現）

[html] view plain copy

package?org.zhy.demo.dao.impl;??

??

import?java.sql.SQLException;??

??

import?org.zhy.demo.dao.IUserDao;??

import?org.zhy.demo.dao.model.UserInfo;??

??

/**??

?*?IUserDao實現，配置完Spring及Hibernate文件后實現此類??

?*?@author?Administrator??

?*??

?*/??

public?class?IUserDaoImpl?implements?IUserDao?{??

??

????@Override??

????public?void?saveUser(UserInfo?user)?throws?SQLException?{??

??

????}??

??

????@Override??

????public?void?delUser(UserInfo?user)?throws?SQLException?{??

??

????}??

??

????@Override??

????public?void?editUsre(UserInfo?user)?throws?SQLException?{??

??

????}??

??

????@Override??

????public?UserInfo?getUserById(int?id)?throws?SQLException?{??

????????return?null;??

????}??

??

}??

Model代碼

[java] view plain copy

package?org.zhy.demo.dao.model;??

??

import?javax.persistence.Entity;??

import?javax.persistence.GeneratedValue;??

import?javax.persistence.Id;??

??

@Entity??

public?class?UserInfo?{??

??

??????

????private?int?id;??

????private?String?name;??

????private?String?title;??

??

????@Id??

????@GeneratedValue??

????public?int?getId()?{??

????????return?id;??

????}??

??

????public?void?setId(int?id)?{??

????????this.id?=?id;??

????}??

??

????public?String?getName()?{??

????????return?name;??

????}??

??

????public?void?setName(String?name)?{??

????????this.name?=?name;??

????}??

??

????public?String?getTitle()?{??

????????return?title;??

????}??

??

????public?void?setTitle(String?title)?{??

????????this.title?=?title;??

????}??

??

}??

下面添加Spring配置文件

在Src目錄下添加SpringContext.xml

[html] view plain copy

修改DAO實現類

[java] view plain copy

package?org.zhy.demo.dao.impl;??

??

import?java.sql.SQLException;??

??

import?org.hibernate.SessionFactory;??

import?org.springframework.orm.hibernate3.HibernateTemplate;??

import?org.zhy.demo.dao.IUserDao;??

import?org.zhy.demo.dao.model.UserInfo;??

??

/**?

?*?IUserDao實現?

?*??

?*?@author?Administrator?

?*??

?*/??

public?class?IUserDaoImpl?implements?IUserDao?{??

??

????private?HibernateTemplate?hibernateTemplate;??

??

????public?void?setSessionFactory(SessionFactory?sessionFactory)?{??

????????this.hibernateTemplate?=?new?HibernateTemplate(sessionFactory);??

????}??

??

????@Override??

????public?void?saveUser(UserInfo?user)?throws?SQLException?{??

????????hibernateTemplate.save(user);??

????}??

??

????@Override??

????public?void?delUser(UserInfo?user)?throws?SQLException?{??

????????hibernateTemplate.delete(user);??

????}??

??

????@Override??

????public?void?editUsre(UserInfo?user)?throws?SQLException?{??

????????hibernateTemplate.update(user);??

????@Override??

????public?UserInfo?getUserById(int?id)?throws?SQLException?{??

????????UserInfo?user?=?(UserInfo)?hibernateTemplate.get(UserInfo.class,?id);??

????????return?user;??

????}??

??

}??

junit測試

[java] view plain copy

@Test??

public?void?saveUserTest()?throws?SQLException{??

????ApplicationContext?context=?new?ClassPathXmlApplicationContext("/SpringContext.xml");??

????UserService?service?=(UserService)?context.getBean("userService");??
