警告: Creating a new instance of CacheManager using the diskStorePath "D:\Apache Tomcat 6.0.18\temp" which is already used by an existing CacheManager.
The source of the configuration was classpath.
The diskStore path for this CacheManager will be set to D:\Apache Tomcat 6.0.18\temp\ehcache_auto_created_1262783591937.
To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.

需要设置2个地方解决这个问题

1.hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

注意需要是Singleton的EhCacheRegionFactory

2.Spring EhCache Beans配置

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="ehcache"/>
</bean>

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="shared" value="true"/>
<property name="configLocation" value="classpath:ehcache.xml"/>
</bean>

注意这里一定要设置shared为true
