jetcache-anno把cacheName作为远程缓存key前缀，2.4.3以前的版本总是把areaName加在cacheName中，因此areaName也出现在key前缀中。

2.4.4以后可以配置，为了保持远程key兼容默认值为true，但是新项目的话false更合理些。

public interface UserService {
    @Cached(name="userCache.", key="#userId", localExpire=300, expire = 600, cacheType=CacheType.BOTH)
    @CacheRefresh(refresh = 100, stopRefreshAfterLastAccess = 1800, refreshLockTimeout=10 )
    @CachePenetrationProtecct
    User getUserById(long userId);
}
