Question

我正在使用Postgresql作为我的数据库，并使用JHipster实体向导创建了所有实体。当我尝试进行任何更改，如添加/删除字段，与现有实体的关系，我收到校验和错误，Liquibase没有启动。另外，我没有手动对数据库进行任何更改。

感谢任何帮助。谢谢。这是我得到的错误：

Answer 1

在Postgres DB中执行以下查询以解决问题：

UPDATE databasechangelog SET md5sum = null

Answer 2

您可以尝试maven目标mvn liquibase:clearCheckSums，然后再次尝试运行应用

希望这有帮助

Answer 3

对于Gradle项目，运行任务liquibaseClearChecksums，例如：

./gradlew liquibaseClearChecksums

Answer 4

如果您正在使用maven：

mvn liquibase:clearCheckSums

否则，如果您使用的是gradle：

./gradlew liquibaseClearChecksums

编辑使用实体向导生成的现有实体时，在JHipster中检查Sum错误
