spring配置hibernate的sessionFactory

1.首先通过dataSource来配置sessionFactory

　　

<!--读入配置文件 -->
    <bean >
            <property name="locations">
                <value>classpath*:jdbc.properties</value>
            </property>
    </bean>
    
    <bean >  
         <property name="driverClassName" value="${jdbc.driverClassName}" />
         <property name="url" value="${jdbc.url}" />
         <property name="username" value="${jdbc.username}" />
         <property name="password" value="${jdbc.password}" />
    </bean> 
    <bean >
        <property name="dataSource" ref="dataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl">update</prop>
            </props>
        </property>
        <property name="mappingResources">
             <list>
                <value>classpath*:/test/domain/MyBean.hbm.xml</value>
                <value>classpath*:/test/domain/BasicBean.hbm.xml</value>
            </list>
