    <!-- 磁盘保存路径 -->
    <diskStore path="D:\\ehcache" />

    <defaultCache
            maxElementsInMemory="10000"
            maxElementsOnDisk="10000000"
            eternal="false"
            overflowToDisk="true"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            diskExpiryThreadIntervalSeconds="120"
