 * @Classname RedisLockUtil 
 * @Description at least we want to ensure that it meets the four conditions: 
 * 1. mutually exclusive: at any given time, only one client can hold a lock 
 * 2. deadlock will not happen: even if there is a client support no active collapse unlocked, but also to ensure the lock during other subsequent 
 * client can lock 
 * 3. the fault tolerant: as long as most of the node redis normal operation, the client can lock and unlock 
 * 4. lock and must be unlocked with a client
