java.lang.IllegalMonitorStateException: 當前線程不是鎖的所有者

Question

我將hazelcast 從2.4 升級到3.3，但是發生了這個異常。

13:12:51,269 [Thread-21]: ERROR xx.xx.xxThread:1783 - run:

3.3中getLock的變化是新版本需要String作為參數。 我只是將它從 Object 更改為 String，沒有其他任何更改。 代碼如下：

Map logins = MyHazelcast.getMap("logins");
Lock lock = MyHazelcast.getLock("logins");
lock.lock();
try
{
     // do something...
}
finally
{
    lock.unlock();
}  

這是由新版本引起的還是我錯過了什么？

Answer 1

> Current thread is not owner of the lock! -> <not-locked>

“未鎖定”表示未找到具有給定密鑰的鎖。 是否有可能在另一個地方使用帶有“登錄”鍵的鎖？

也許您在代碼中的某處釋放了鎖？

我將從這個鎖的唯一鍵名開始。
