hibernate4.1.2使用ehcache2.4.3实现二级缓存时报错

我的异常已解决，就借鉴一下人家的异常吧

In my application I use the hibernate-core-4.1.8 jar and would like to take an ehCache as 2nd level cache. The jar I am currently using is ehcache-core-2.5.0. I placed it in my WebContetn/WEB-INF/lib folder and put it in the classpath too.

My hibernate.cfg.xml looks like this:

<hibernate-configuration>
    <session-factory>   
    ....    
        <property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>
        <property name="hibernate.cache.use_second_level_cache">true</property>
        <property name="hibernate.cache.use_query_cache">true</property>
    </session-factory>
</hibernate-configuration>

ehcache.xml配置文件

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true"
        monitoring="autodetect" dynamicConfig="true">

    <defaultCache
                maxElementsInMemory="100000"
                eternal="false"
                timeToIdleSeconds="1000"
                timeToLiveSeconds="1000"
                overflowToDisk="false"
                />
</ehcache>

异常：

解决办法：

you need to include hibernate-ehcache.jar by downloading it or is you're using maven put it in your dependencies like thi
