mysql 一個被誤導的錯誤：

mysql jdbc連線，資料庫ip變成了本地ip？

java.sql.SQLException: Access denied foruser 'btir'@'172.43.5.48' (using password: YES)

一個被誤導的錯誤，看到這個錯誤時忘了可能是密碼錯了，因為這個東西是其他同事配置好的，所以沒有多想，而且加上之前用過ssh登入命令，ssh的命令是這樣格式的：

ssh -p 12333 [email protected]

沒錯，都有這種格式 [email protected]，於是頭腦昏了，以為資料庫連錯了，連到了本地ip（172.43.5.48

浪費好多時間。

實際上這句報錯的意思就是mysql連線密碼錯了：

Access denied for user 'btir'@'172.43.5.48' (using password: YES)

btir是你用的登入使用者名稱，而@後面的ip就是登入時的ip，不是資料庫所在的ip！

附上關於ssh命令的說明：

ssh命令用於遠端登入上Linux主機。

常用格式：ssh [-l login_name] [-p port] [[email protected]

@後面是你要登入的主機域名或ip，這一點與上面的報錯資訊不一樣。

附上程式報錯資訊：
