hibernate使用需要配置以下几个方面。

1.配置数据源

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/testroom?useUnicode=true&amp;characterEncoding=UTF-8"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>

2.配置sessionFactory工厂

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.connection.autocommit">true</prop>
            </props>
        </property>
　　　　　<!-- 配置 hibernate模型对象映射文件-->
        <property name="mappingResources">
            <list>
                <value>cn/lt/entity/User.hbm.xml</value>
                <value>cn/lt/entity/Questions.hbm.xml</value>
                <value>cn/lt/entity/fraction.hbm.xml</value>
            </list>
        </property>
    </bean>

3.配置事务管理

<bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <!--配置 注解-->
    <tx:annotation-driven transaction-manager="transactionManager" /></beans>
