我有一个项目，我使用Ehcache技术的弹簧缓存。我也使用hibernate作为jpa提供程序。 我的请求方法调用创建了几个用于数据处理的线程。
当我在ehcache.xml中为我的服务模块的每个方法使用不同的缓存时，它运行良好，如下所示：
<cache name="rrr1"
maxEntriesLocalHeap="10000"
maxEntriesLocalDisk="100000000"
eternal="false"
diskSpoolBufferSizeMB="20"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU"
overflowToDisk="false"
diskPersistent="false"
transactionalMode="off">
</cache>
<cache name="rrr2"
maxEntriesLocalHeap="10000"
maxEntriesLocalDisk="100000000"
eternal="false"
diskSpoolBufferSizeMB="20"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU"
overflowToDisk="false"
diskPersistent="false"
transactionalMode="off">
</cache>
<cache name="rrr3"
maxEntriesLocalHeap="10000"
maxEntriesLocalDisk="100000000"
eternal="false"
diskSpoolBufferSizeMB="20"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU"
overflowToDisk="false"
diskPersistent="false"
transactionalMode="off">
</cache>
但是当我尝试为我的方法设置单个缓存时，我遇到了这样的问题：

为什么会这样？
