連不到你底層資料庫妳再確定一下 sql.propites 設定的資料庫連線是否正確 我也有一樣的問題，目前還不知道應該如何解決才對 不好意思,目前也遇到相同問題,頭痛中....:'( 一般都是 java 這邊的問題. 大大雖然時間過了很久,但是今天有大大幫忙解決了我的問題,可能是mysql sever版本的問題,我本來是8.0後來改成5.5版就可以了,有機會你可以試試 hinroung 發表於 2019-8-30 10:24

我也遇過這個問題
後來下載mysql-installer-community-8.0.17.0
不管裝幾次都失敗
後來GOOGLE教學
後來發現有一個地方程式更新後就沒問題了
忘記是哪邊了 你可以研究一下
感謝分享唷
