spring整合hibernate

1.引入jar包

(spring开发包,ojdbc.jar,dbcp连接池,hibernate框架开发包)

2.新建applicationContext-hibernate.xml

首先，配置好数据源dataSource，
其次，加入SessionFactory，
第三，配置映射文件

spring配置文件例子:
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xmlns:tx="http://www.springframework.org/schema/tx"

        xmlns:aop="http://www.springframework.org/schema/aop"

        xmlns:context="http://www.springframework.org/schema/context"

        xmlns:jee="http://www.springframework.org/schema/jee"

        xsi:schemaLocation="

            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd

            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd

            http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd">

    <bean id="mydataSource" destroy-method="close"

        class="org.apache.commons.dbcp.BasicDataSource">

        <property name="driverClassName"

            value="oracle.jdbc.OracleDriver">

        </property>

        <property name="url"

            value="jdbc:oracle:thin:@192.168.0.20:1521:tarena">

        </property>

        <property name="username" value="task">

        </property>

        <property name="password" value="mistarena">

        </property>

        <property name="initialSize" value="2">

        </property>

        <property name="maxActive" value="15">

        </property>

    </bean>

   

    <bean id="sessionFactory"

    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

        <!-- 注入dataSource连接资源 -->

        <property name="dataSource"

            ref="mydataSource">

        </property>

        <!-- 注入hibernate配置参数 -->

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>

                <prop key="hibernate.show_sql">true</prop>

                <prop key="hibernate.format_sql">true</prop>

            </props>

        </property>

        <!-- 注入hibernate映射描述文件 -->

        <property name="mappingResources">

            <list>

                <value>tarena/entity/Fee.hbm.xml</value>

            </list>

        </property>

    </bean>

</beans>

 

3.新建实体类

4.新建xxx.hbm.xml映射文件

5.新建dao接口

6.新建dao接口实现类，继承HibernateDaoSupport

7.修改spring配置文件,加入dao实现类的bean，

在bean中注入sessionFactory

例子:
    <bean id="hibernateFeeDAO" class="tarena.dao.HibernateFeeDAO">

        <property name="sessionFactory" ref="sessionFactory">

        </property>

    </bean>

8.dao实现类代码例子

public class HibernateFeeDAO extends HibernateDaoSupport implements FeeDAO{

    public void delete(Fee fee) {

        this.getHibernateTemplate().delete(fee);

    }

    public List<Fee> findAll() {

        String hql = "from Fee";

        List<Fee> list = this.getHibernateTemplate().find(hql);

        return list;

    }

    public Fee findById(int id) {

        Fee fee = (Fee)this.getHibernateTemplate().get(Fee.class, id);

        return fee;

    }

    public void save(Fee fee) {

        this.getHibernateTemplate().save(fee);

    }

    public void update(Fee fee) {

        this.getHibernateTemplate().update(fee);

    }

}
