zookeeper curator 分布式锁，zk服务停了，如何保证业务逻辑的正常处理InterProcessMutex lock = new InterProcessMutex(client, path);if (lock.acquire(10 * 1000, TimeUnit.SECONDS)) {doSth();}如果zk连接失败，如何跳过锁判断，执行下面的业务逻辑，不至于业务瘫痪呢各位大神求支招

当连接失败的时候，acquire会马上抛出异常的，你只要把异常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
