在我的jHipster项目上启动Embedded Tomcat时出现此烦人的错误。花了很多时间尝试解决它，但无法弄清楚它为什么会发生。从主要代表处更新项目后，它开始发生，但我也实现了自定义存储库。

最佳答案
众所周知， Liquibase 将所有更改日志写入数据库中名为 databasechangelog 的表中，如下所示:
当发生类似的错误时，我通过更改数据库中数据库changelog 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查询来解决此问题:
UPDATE `databasechangelog` SET `MD5SUM`=`7:bde7b076d47aefe8278d126cde26b172` WHERE `ID`=`00000000000001`;
其他解决方案
截断
databasechangelog表。如下所示，在 pom.xml 文件的适当位置添加无液体:<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!
