<!--
属性说明:
l diskStore:指定数据在磁盘中的存储位置。
l defaultCache:当借助CacheManager.add("demoCache")创建Cache时,EhCache便会采用<defalutCache/>指定的的管理策略
以下属性是必须的:
l maxElementsInMemory - 在内存中缓存的element的最大数目
l maxElementsOnDisk - 在磁盘上缓存的element的最大数目,若是0表示无穷大
l eternal - 设定缓存的elements是否永远不过期。如果为true,则缓存的数据始终有效,如果为false那么还要根据timeToIdleSeconds,timeToLiveSeconds判断
l overflowToDisk - 设定当内存缓存溢出的时候是否将过期的element缓存到磁盘上
以下属性是可选的:
l timeToIdleSeconds - 当缓存在EhCache中的数据前后两次访问的时间超过timeToIdleSeconds的属性取值时,这些数据便会删除,默认值是0,也就是可闲置时间无穷大
l timeToLiveSeconds - 缓存element的有效生命期,默认是0.,也就是element存活时间无穷大
diskSpoolBufferSizeMB 这个参数设置DiskStore(磁盘缓存)的缓存区大小.默认是30MB.每个Cache都应该有自己的一个缓冲区.
l diskPersistent - 在VM重启的时候是否启用磁盘保存EhCache中的数据,默认是false。
l diskExpiryThreadIntervalSeconds - 磁盘缓存的清理线程运行间隔,默认是120秒。每个120s,相应的线程会进行一次EhCache中数据的清理工作
l memoryStoreEvictionPolicy - 当内存缓存达到最大,有新的element加入的时候, 移除缓存中element的策略。默认是LRU(最近最少使用),可选的有LFU(最不常使用)和FIFO(先进先出)
