本文介紹了帶有MySQL后端的JHipster在第一次啟動時失敗，因為表不符合外部插件的要求的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)吧！
問題描述
嘗試使用MySQL作為數(shù)據(jù)庫啟動新的JHipster應(yīng)用程序時出現(xiàn)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(fā)生這種情況嗎？
推薦答案
Liquibase不使用所需的主鍵創(chuàng)建DATABASECHANGELOG表。嘗試停止JHipster，對MySQL數(shù)據(jù)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(yīng)該可以解決問題。
這篇關(guān)于帶有MySQL后端的JHipster在第一次啟動時失敗，因為表不符合外部插件的要求的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，
