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"
/>
