Question

我按照文章https://www.jhipster.tech/tips/025_tip_create_new_authority.html中的那些说明添加了一个新权限“ROLE_CLIENT”之后，我重新启动了我的项目，出现了一个错误：

顺便说一句，我使用的是微服务架构和JWT认证。

Answer 1

这是正常的：Liquibase 变更集应该是 immutable。

这就是为什么 Liquibase 在数据库变更日志 table 中记录每个变更集条目的 md5 校验和，以检测当前变更日志中的内容与实际运行数据库中的内容之间的差异。

当您修改 authority.csv 时，变更集的校验和发生了变化，Liquibase 正确地抱怨了。

因此，您有 3 个备选解决方案：

创建一个单独的变更集以仅插入您的新权限（生产中的首选方式）
在使用像 DBeaver 这样的数据库客户端连接到数据库时清除变更集的校验和列，并删除 DATABASECHANGELOG table 中变更日志行的 MD5SUM 列。看看https://docs.liquibase.com/concepts/basic/databasechangelog-table.html
删除您的数据库以从头开始重新启动，如果您不关心您的数据，这可能适用于开发数据库

最后的建议：从 official docs also from JHipster doc
