磁盘存储ehcache的Spring ACL问题

Question

我试图实现Spring ACL，但我遇到了一个问题，我不知道如何解决。

我们有一个运行配置的echache，它是从以下spring环境加载的。

ehcache看起来像：

    <defaultCache
            maxElementsInMemory="10000"
            maxElementsOnDisk="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            diskExpiryThreadIntervalSeconds="120"
            statistics="true"
            memoryStoreEvictionPolicy="LRU"/>


    <cache name="dk.platform.model.Alarm"
           maxElementsInMemory="2000"
           eternal="false"
           timeToIdleSeconds="360"
           timeToLiveSeconds="360">
    </cache>
    ...

我尝试删除ehcache中的<diskStore path="java.io.tmpdir"/>行，但无济于事。

编辑

Spring版本：3.2.4.RELEASE

Ehcache版本：4.1.9.Final

根据EhCache文档，您可以通过将overflowToDisk属性设置为false来关闭缓存的磁盘使用率。所以你可以试试：

<defaultCache
        maxElementsInMemory="10000"
        overflowToDisk="false"
        eternal="false"
        timeToIdleSeconds="120"
        timeToLiveSeconds="120"
        diskExpiryThreadIntervalSeconds="120"
        statistics="true"
        memoryStoreEvictionPolicy="LRU"/>
