在我的jHipster项目上启动Embedded Tomcat时出现这个恼人的错误。花了很多时间试图解决它，但无法弄清楚它为什么会发生。它是在从主代表更新项目后开始发生的，但我也实现了自定义存储库。

答案 0 :(得分：1)
众所周知， Liquibase 将所有变更日志写入数据库中名为 databasechangelog 的表中，
所有Liquibase更改的根都是databaseChangeLog文件。
发生类似错误时，我通过更改数据库的 databasechangelog 表中的校验和值来手动解决了该错误。您可以通过在数据库中运行以下SQL查询来解决该问题：
UPDATE `databasechangelog` SET `MD5SUM`=`7:bde7b076d47aefe8278d126cde26b172` WHERE `ID`=`00000000000001`;
另一种解决方法
截断databasechangelog表。如下所示，在 pom.xml 文件中的适当位置添加 no-liquibase ：
<properties>
<spring.profiles.active>local,no-liquibase</spring.profiles.active>
</properties>
然后运行 mvnw ，该应用程序将成功启动！

我多次遇到此问题，对我而言，最快的方法是删除所有带有已生成记录的表，然后重新运行该应用程序。
答案 2 :(得分：0)
我在运行flowable-admin时遇到了类似的错误，该方法也与spring一起使用liquibase
Flask-Migrate我也通过修改设置为 true 的 databasechangeloglock 表使用了上述建议，这显然是由于在对 databasechanglog进行更改时出错已严重终止。将其设置为 false 即可解决此问题，并且flowable-admin启动正常。

我使用rancher v1，我需要在mysql数据库中运行它：
DELETE FROM DATABASECHANGELOGLOCK where ID = 1;
答案 4 :(得分：0)
就我而言，这是因为文件未正确加载。
我使用includeAll来显示liquibase包含文件的位置。
databaseChangeLog:
- includeAll:
path: classpath*:db/changelog/changes/
- include:
file: db/changelog/changes/a.yaml
答案 5 :(得分：0)
我有同样的问题。我的解决方案是这样的：
开放;
*数据库表（mySql或postgresql或其他）
*数据库更改日志表
更改;
* Locked = false
我以这种方式达成了解决方案。我希望它能解决您的问题。
