2 回答報錯：Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8

4 回答頁面調用登錄失敗，控制臺報No suitable driver found for jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8 org.hibernate.exception.JDBCConnectionException: Could not open connection，在action打印用戶登錄名為空

1 回答為什么總是提示No suitable driver found？

1 回答No appenders could be found for logger (org.hibernate.cfg.Environment).

2 回答jdbc:mysql://localhost:3306/test和jdbc:mysql:///test是一個意思吧？多一個“/”表示本地的默認端口嗎？
