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

在bean.xml檔案中，這樣使用出現問題
<!-- 指定使用hibernate核心配置檔案 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
報錯如下：

應該修改成下面這樣
<!-- sessionFactory建立 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 指定使用hibernate核心配置檔案中，沒有資料庫配置，資料庫配置在spring裡面配置，注入dataSource --> <property name="dataSource" ref="dataSource"></property> <!-- 指定使用hibernate核心配置檔案 --> <!-- <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>
只知道修改之後沒有問題，但是到底是什麼原因未知。
