Hibernate 映射Oracle中的表，为什么会用到MySQL的包？?报错

各位大神，小菜鸟有一个疑惑。一个项目里面链接了两个数据库，分别是MySQL和Oracle，他们的DateSource和SessionFactory如下：

<!--start 配置DATASOURCES -->
	<bean id="dataSourceOracle" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<!-- <property name="name" value="${oracle.driverClassName}" /> -->
		<property name="url" value="${oracle.dailypre_url}" />
		<property name="username" value="${oracle.username}" />
		<property name="password" value="${oracle.password}" />
		<property name="maxOpenPreparedStatements" value="100"/>

		<property name="maxActive" value="${druid.max_size}" />
		<property name="filters" value="config" />
		<!-- 配置数据库加密 -->
		<property name="connectionProperties"
			value="config.decrypt=true;config.decrypt.key=${oracle.publickey}" />
	</bean>

	<bean id="dataSourceMySQL" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<!-- <property name="name" value="${mysql.driverClassName}" /> 可根据URL自动判断出DBDRIVER-->
		<property name="url" value="${mysql.dailyreport_url}" />
		<property name="username" value="${mysql.username}" />
		<property name="password" value="${mysql.password}" />

		<property name="maxActive" value="${druid.max_size}" />
		<property name="filters" value="config" />
		<!-- 配置数据库加密 -->
		<property name="connectionProperties"
			value="config.decrypt=true;config.decrypt.key=${mysql.publickey}" />
	</bean>
	<!--end 配置DATASOURCES -->

	<!--start 配置SessionFactory-->
	<bean id="sessionFactoryMySQL"
		class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSourceMySQL"></property>
		<!-- 注解的实体类通过此扫描的方式注入 -->
		<property name="packagesToScan" value="org.daily.**.entity" />
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
				<!-- hibernate.current_session_context_class此处与Spring2.x不同，不能为thread，否则报错:?? 
					is not valid without active transaction -->
				<prop key="hibernate.current_session_context_class">
					org.springframework.orm.hibernate5.SpringSessionContext
				</prop>
			</props>
		</property>
	</bean>

	<bean id="sessionFactoryOracle"
		class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSourceOracle"></property>
		<!-- 注解的实体类通过此扫描的方式注入 -->
		<property name="packagesToScan" value="org.daily.**.entity" />
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<!-- hibernate.current_session_context_class此处与Spring2.x不同，不能为thread，否则报错:?? 
					is not valid without active transaction -->
				<prop key="hibernate.current_session_context_class">
					org.springframework.orm.hibernate5.SpringSessionContext
				</prop>
			</props>
		</property>
	</bean>
	<!--end 配置SessionFactory-->

现提取MySQL数据库中的数据时，没有问题。

但是当提取Oracle中数据时，进行查询测试，

报错，如下：
