解决idea调试过程中liquibase – Waiting for changelog lock….导致数据库死锁问题

1. 出现原因可能为idea运行时频繁，导致Jar包启动报错,工作流表部分日志表被锁，可能上次未正常终止程序导致的异常。

2021-02-14 13:45:13.735 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:45:23.739 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:45:33.744 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:45:43.750 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:45:53.755 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:46:03.762 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:46:13.767 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:46:23.773 [main] INFO  liquibase - Waiting for changelog lock....

2. 借鉴网上说是表被锁，解除锁定就行，可执行下面的语句，但是提示找不到表或试图不存在

#查询被锁的表
SELECT * FROM DATABASECHANGELOGLOCK;
#解除锁定
UPDATE DATABASECHANGELOGLOCK SET locked=0, lockgranted=null, lockedby=null WHERE id=1

3. 解决办法（所有以DATABASECHANGELOGLOCK结尾的表都检查一遍，并修改locked字段的值为0即可，如：图2
   
   4、重新运行项目，即可显示运行正常。
