問題描述
嘗試使用MySQL作為數據庫啟動新的JHipster應用程序時出現以下錯誤：

它看起來像是在液基臺階上失敗了。你知道為什么會發生這種情況嗎？
推薦答案
Liquibase不使用所需的主鍵創建DATABASECHANGELOG表。嘗試停止JHipster，對MySQL數據庫運行以下SQL命令，然后重新啟動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;
這應該可以解決問題。
