Spring学习-9-Spring与Hibernate整合

Spring与Hibernate整合

步骤

1)引入jar包

连接池/数据库驱动包

Hibernate相关jar包

Spring 核心包和aop包

Spring-orm

Spring-tx

2)配置

hibernate.cfg.xml

bean.xml

3)搭建

package com.cx.entity;

/**
 * Created by cxspace on 16-8-11.
 */
public class Dept {

    private int id;
    private String name;

    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;
    }
}

package com.cx.dao;

    <!--方式一：直接加载hibernate.cfg.xml文件方式整合-->

    <!--

        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
    </bean>

    <!--方式二.连接池交给spring管理-->

    <!--
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
        <property name="dataSource" ref="dataSource"></property>

    <!--最佳方式sessionFactory配置,spring与hibernate整合  hibernate.cfg.xml中的内容写道bean.xml中 -->

        <!--注入连接池对象-->
