更改缓存后，线上日志报了一个缓存错误 [ERROR]-[Thread: five%004dinute.data]-[net.sf.ehcache.store.disk.DiskStorageFactory$DiskWriteTask.call()]: Disk Write of get-goods-byUuid-0d695dbae6574a19963c412e19c6cc8d failed: net.sf.ehcache.CacheException: Failed to serialize element due to ConcurrentModificationException. This is frequently the result of inappropriately sharing thread unsafe object (eg. ArrayList, HashMap, etc) between threads at net.sf.ehcache.store.disk.DiskStorageFactory.serializeElement(DiskStorageFactory.java:405) at net.sf.ehcache.store.disk.DiskStorageFactory.write(DiskStorageFactory.java:385) at net.sf.ehcache.store.disk.DiskStorageFactory$DiskWriteTask.call(DiskStorageFactory.java:477) at net.sf.ehcache.store.disk.DiskStorageFactory$PersistentDiskWriteTask.call(DiskStorageFactory.java:1071) at net.sf.ehcache.store.disk.DiskStorageFactory$PersistentDiskWriteTask.call(DiskStorageFactory.java:1055) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:178)
代码如下：
String goodsCacheKey = PropKit.get("SYSTEMID")+"get-goods-byUuid-"+uuid;
Goods goods = CacheKit.get("fiveMinute", goodsCacheKey);
if (goods == null) {
goods = srv.getIsSaleGoodByUuid(uuid, pid);
CacheKit.put("fiveMinute", goodsCacheKey, goods);
}调查后发现说是可能内存数据被多次修改的问题，需要重新new新的出来，我想问下波总，我看了下最新文档，使用上也没有提需要这样的操作，如果真是这个问题的话jfinal直接在返回的时候实现下是不是更好？
注：jfinal版本是3.3
项目：JFinal
