针对根本原因的任何解决方案都会有所帮助.

解决方法:

更新您的ehcache.xml并在root ehcache元素中设置updateCheck =“false”,如下所示：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="ehcache.xsd"
         updateCheck="false" monitoring="autodetect"
         dynamicConfig="true" name="TestCache" >
