林老被

這幾天放假閒著，剛好逛到ZZMS的教學
於是我照著影片步驟做
但是一打開伺服端就發生

嚴重: Unable to create initial connections of pool.

ERRORcom.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
初始化角色訊息錯誤:java.lang.NullPointerException

這樣的問題，我JAVA也有裝
且我用MySQL開啟連線 密碼輸入root
卻無法連線，錯誤訊息是
1045-Access denied for user 'root'@'localhost' (using password:YES)

請教各位大大 如何解決呢?
