是缓存路径问题

 

首先说明：我们在ehcache.xml  <diskStore path="java.io.tmpdir"/>配置了缓存溢出到的磁盘路径

可以通过：

System.out.println(System.getProperty("java.io.tmpdir"));

在文件按目录下有一下文件：
com.eric.po.B.data--------0kb
cache_a.data   ------------4 kb
org.hibernate.cache.StandardQueryCache.data  ---0kb
org.hibernate.cache.UpdateTimestampsCache.data -----0kb

在文件按目录下有一下文件：
com.eric.po.B.data--------0kb
cache_a.data   ------------4 kb
org.hibernate.cache.StandardQueryCache.data  ---0kb
org.hibernate.cache.UpdateTimestampsCache.data -----0kb

 
其中   cache_a中保存了我们的缓存文件

StandardQueryCache.data 则是 设置默认的查询缓存的数据过期策略  产生的文件，

org.hibernate.cache.UpdateTimestampsCache.data则是 设置时间戳缓存的数据过期策略 

如果不适用我们自己的缓存配置就会使用类类的全路径路径文件（com.eric.po.B.data）来缓存我们的数据。
