Could not instantiate cache implementation异常处理

今天遇到了一个很奇怪的问题  我照例增加了一套新功能，但一切就绪调试的时候，报了这个错

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/classes/application-dao.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Could not instantiate cache implementation

解决办法：

我们这个工程并没有写hibernate.hbm.xml文件，直接在spring配置文件里写的。无奈我又新建了这个文件。以下是内容：

<!DOCTYPE hibernate-configuration PUBLIC
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
 <session-factory>
  <property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
        <property name="hibernate.cache.use_second_level_cache">false</property>
        <property name="hibernate.cache.use_query_cache">false</property>
 </session-factory>
</hibernate-configuration>

 

 

在spring配置文件中加入了下面的属性：

<property name="configLocation">
   <value>classpath:hibernate.cfg.xml</value>
  </property>

 

重启Tomcat后，ok了。

如果已经有对应的hibernte-cfg.xml文件，还是报这个错怎么办
