當(dāng)連接失敗的時(shí)候，acquire會(huì)馬上拋出異常的，你只要把異常catch住就好


public boolean acquire(long time,

                       TimeUnit unit)

                throws Exception

                

Acquire the mutex - blocks until it's available or the given time expires. Note: the same thread can call acquire re-entrantly. Each call to acquire that returns true must be balanced by a call to release()


Specified by:

acquire in interface InterProcessLock


Parameters:

time - time to wait

unit - time unit


Returns:

true if the mutex was acquired, false if not


Throws:

Exception - ZK errors, connection interruptions
