启动应用花了好长时间，最后报出异常.
异常：

Caused by: liquibase.exception.LockException: Could not acquire change log lock.

原因分析：

“liquibase.exception.LockException: Could not acquire change log lock. ”

select * from DATABASECHANGELOGLOCK;

可以判断是出现了分布式锁异常

---

解决方案：

update DATABASECHANGELOGLOCK set LOCKED="", LOCKGRANTED=null, LOCKEDBY=null where ID=1;
