私はehcache.xmlに次のものを持っています
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false" >
<defaultCache
maxElementsInMemory="500"
eternal="false"
overflowToDisk="false"
overflowToOffHeap="false"
memoryStoreEvictionPolicy="LRU" >
<persistence strategy="none" />
</defaultCache>
<cache name="leadSourceCollectionsCache"
maxElementsInMemory="500"
eternal="false"
overflowToDisk="false"
overflowToOffHeap="false"
memoryStoreEvictionPolicy="LRU" >
<persistence strategy="none" />
</cache>
</ehcache>
サーバーを起動すると、次の ehcache 関連のデバッグ出力が表示されます

したがって、LeadSourceCollectionCache をメモリ ストア キャッシュとして作成しているように見えますが、これは私が望むものです。ただし、leadSourceCollectionCache.put を呼び出すと、次のようになります。

なぜこれが起こっているのか、一生理解できません。キャッシュがディスクに触れないようにしたいです。また、永続性がなしに設定されているときに /tmp に書き込もうとする理由もわかりません。
