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

Lorsque la connexion échoue, l'acquisition lèvera immédiatement une exception. Il vous suffit d'intercepter l'exception
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
