【Spring】Spring框架如何集成Hibernate框架

下面个整理一下hibernate和Spring框架的结合。

首先是引入hibernate框架的包、Spring框架的包、数据库驱动包。

User.java文件

package cn.shop.bean;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="user")
public class User {
    
    @Id
    @Column(name="uid")
    private int id;
    
    @Column(name="uname")
    private String name;
    
    @Column(name="upass")
    private String password;
    
    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 getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

hibernate.cfg.xml文件

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

    <session-factory>
        <property name="dialect">
            org.hibernate.dialect.MySQLDialect
        </property>
        
        <!-- 加载映射描述信息 -->
        <mapping class="cn.shop.bean.User" />
        
    </session-factory>
</hibernate-configuration>

applicationContext.xml文件

        </property>
        <property name="dataSource" ref="c3p0"></property>
    </bean>
    
    
</beans>

db-config.properties文件

db.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
db.username=root
db.password=517839
db.dirverClass=com.mysql.jdbc.Driver

UserDao.java文件

package cn.shop.dao;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;

import cn.shop.bean.User;

@Repository("userDao")
public class UserDao {

    @Resource
    private HibernateTemplate template;
    
    public List findUserById(String name,String password){
        return template.find("from User where name=? and password=?",name,password);
    }
}

到这里就配置到Dao层了，使用如下代码进行测试：

        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
        UserDao userdao= ac.getBean("userDao",UserDao.class);
        List<User> find = userdao.findUserById("honny","123456");
        for(User user:find){
            System.out.println(user);
        }
