带有MySQL后端的JHipster在第一次启动时失败，因为表不符合外部插件的要求

问题描述

尝试使用MySQL作为数据库启动新的JHipster应用程序时出现以下错误：

它看起来像是在液基台阶上失败了。你知道为什么会发生这种情况吗？

推荐答案

Liquibase不使用所需的主键创建DATABASECHANGELOG表。尝试停止JHipster，对MySQL数据库运行以下SQL命令，然后重新启动JHipster：

ALTER TABLE DATABASECHANGELOG
ADD PRIMARY KEY (ID);

drop table jhi_persistent_audit_evt_data;

drop table jhi_persistent_audit_event;

drop table jhi_user_authority;

drop table jhi_authority;

drop table jhi_user;

这应该可以解决问题。
