当时遇到这个问题，也是在网上找了许久的答案，后来被宿舍大神一句话解决：版本号相匹配。

下例：

我们在编写源码时候，在java源代码中的TibernateTemplate的版本号是 5,那么在xml文件配置的时候也是 5。

xxx.java

import org.springframework.orm.hibernate5.HibernateTemplate;

protected HibernateTemplate hibernateTemplate;

applicationContext.xml

<!-- 事务管理器  -->

    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">

        <property name="sessionFactory" ref="sessionFactory"/>

      </bean>

细节决定成败。使用如eclipse等IDE工具，在带来方便的同时，也会让我们忽略一些问题。
