Spring整合Hibernate图文步骤

2023-01-25 20:06:54

首先建立java Project工程

点击Finish完成

添加Hibernate和Spring所需要的jar包还有Mysql连接的jar包

创建Dao层，Dao层实现，Model层，Service层

DAO层代码：IUserDao

package org.zhy.demo.dao;
import java.sql.SQLException;
import org.zhy.demo.dao.model.UserInfo;
/**
* DAO层简单的增删改查方法
* @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层实现（暂时空实现）

package org.zhy.demo.dao.impl;
import java.sql.SQLException;
import org.zhy.demo.dao.IUserDao;
import org.zhy.demo.dao.model.UserInfo;
/**
* IUserDao实现，配置完Spring及Hibernate文件后实现此类
* @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代码

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目录下添加SpringContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>

修改DAO实现类

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实现
*
* @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测试

@Test
public void saveUserTest() throws SQLException{
ApplicationContext context= new ClassPathXmlApplicationContext("/SpringContext.xml");
UserService service =(UserService) context.getBean("userService");
UserInfo user = new UserInfo();
user.setName("T`");
user.setTitle("CSDN BLOG");
service.addUserInfo(user);
}
