使用 <!-- 指定使用hibernate核心配置文件 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>

在bean.xml文件中，这样使用出现问题

<!-- 指定使用hibernate核心配置文件 -->
<property name="configLocations" value="classpath:hibernate.cfg.xml"></property>

报错如下：

应该修改成下面这样

<!-- sessionFactory创建 -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 指定使用hibernate核心配置文件中，没有数据库配置，数据库配置在spring里面配置，注入dataSource -->
        <property name="dataSource" ref="dataSource"></property>

        <!-- 指定使用hibernate核心配置文件 -->
        <!-- <property name="configLocations" value="classpath:hibernate.cfg.xml"></property> -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            </props>
        </property>
    </bean>

只知道修改之后没有问题，但是到底是什么原因未知。
