Spring使用ehcache进行休眠和缓存

我正在使用spring 3.2和hibernate 4.2.8并尝试使用ehcache但是当我使用@Cache（org.hibernate.annotations.Cache）注释实体类时，我得到以下异常

Caused by: org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given, please either disable second level cache or set correct region factory class name to property hibernate.cache.region.factory_class (and make sure the second level cache provider, hibernate-infinispan, for example, is available in the classpath).

我的配置如下所示

<bean id="sessionFactoryAdmin"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="adminDataSource" />
        <property name="packagesToScan" value="com.digilegal.services.ahc.model.user" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <!-- <prop key="hibernate.hbm2ddl.auto">update</prop> -->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
                <prop key="hibernate.cache.provider_configuration">/WEB-INF/ehcache-entity.xml</prop>
                <prop key="hibernate.cache.use_second_level_cache">true</prop>
                <prop key="hibernate.cache.use_query_cache">true</prop>
            </props>
        </property>
    </bean>

我在互联网上尝试了所有可能的链接，但无法解决问题

这是我的/WEB-INF/ehcache-entity.xml

<?xml version="1.0" encoding="UTF-8"?>
    <ehcache>
    <cache name="com.digilegal.services.ahc.model.user.UserNotifications"
        maxElementsInMemory="500"
        eternal="false"
        overflowToDisk="false"
        timeToIdleSeconds="69"
        timeToLiveSeconds="65" />


    <cache name="org.hibernate.cache.StandardQueryCache"
        maxEntriesLocalHeap="15" eternal="false" timeToLiveSeconds="60"
        overflowToDisk="true" />
</ehcache>
