在我的 jHipster 项目上启动嵌入式 Tomcat 时，我遇到了这个恼人的错误。花了很多时间试图解决它，但无法弄清楚为什么会发生。它是在主要代表更新项目后开始发生的，但我也实现了自定义存储库。

众所周知的事实是液体碱将所有变更日志写入名为的表中数据库变更日志在您的数据库中为：
所有 Liquibase 更改的根源是databaseChangeLog 文件。
当我遇到类似的错误时，我通过更改中的校验和值手动解决了它数据库变更日志我的数据库中的表。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桌子。添加无液体碱在适当的地方pom.xml文件如下：
<properties>
<spring.profiles.active>local,no-liquibase</spring.profiles.active>
</properties>
然后运行mvn (or mvnw，根据您的项目设置），应用程序将成功启动！
