No configuration found. Configuring ehcache from ehcachefailsafe.xml 警告的解决方案

No configuration found. Configuring ehcache from ehcache-failsafe.xml 解决方案

No configuration found. Configuring ehcache from ehcache-failsafe.xml 。ehcache-failsafe.xml 是来自于ehcache-1.1.jar包，但原因并不是找不到 ehcache-failsafe.xml 而造成的错误，把 ehcache-1.1.jar包里的 ehcache-failsafe.xml 抽取出来，改名为ehcache.xml放到工程的Src目录下，刷新一下并运行，OK，没有警告了！

一般伴随这个的，还有下面两个警告：

Could not find configuration [org.hibernate.cache.UpdateTimestampsCache]; using defaults.
Could not find configuration [org.hibernate.cache.StandardQueryCache]; using defaults.

原因就是你配置了spring二级缓存不完全造成的

参见下面的文章：

1.首先,在spring的hibernate配置里(我的是applicationContext-hibernate.xml) 加上如下属性:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">         
   <property name="dataSource">
    <ref bean="dataSource"/>
   </property>
   <property name="mappingResources">
    <list>
     <value>org/appfteaching/model/TArticleclass.hbm.xml</value>
    </list>
   </property>
   <property name="hibernateProperties">
    <props>
     <prop key="hibernate.dialect">${hibernate.dialect}</prop>
          <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
          <prop key="hibernate.jdbc.fetch_size">${hibernate.jdbc.fetch_size}</prop>
          <prop key="hibernate.jdbc.batch_size">${hibernate.jdbc.batch_size}</prop>
          <prop key="hibernate.cache.use_query_cache">true</prop>
          <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
    </props>   
   </property>  
</bean>

2.其次,在src目录下的ehcache.xml中配置如下信息(如果是默认ehcache.xml则会有<cache name="sampleCache1">和<cache name="sampleCache2>",去掉)

<cache name="org.hibernate.cache.StandardQueryCache"
        maxElementsInMemory="10000"
        eternal="false"
        timeToIdleSeconds="300"
        timeToLiveSeconds="4200"
        overflowToDisk="true"
        />

    <!-- Sample cache named sampleCache2
        This cache contains 1000 elements. Elements will always be held in memory.
        They are not expired. -->

    <cache name="org.hibernate.cache.UpdateTimestampsCache"
        maxElementsInMemory="5000"
        eternal="true"
        timeToIdleSeconds="0"
        timeToLiveSeconds="0"
        overflowToDisk="false"
        />

3.将你要缓存的model加进ehcache.xml里

<cache name="org.appfteaching.model.TArticleclass"
    maxElementsInMemory="1000"
        eternal="false"
        timeToIdleSeconds="100"
        timeToLiveSeconds="4200"
        overflowToDisk="true"
    />
