MySQL java數據庫。拒絕訪問用戶

-2

我正在嘗試製作一個java數據庫。我正在使用IntelliJ和eclipse。這是我收到的日食：MySQL java數據庫。拒絕訪問用戶

，這裏是我收到的IntelliJ：

    in LocalDataSource.getConnection(LocalDataSource.java:269)

我用的數據庫名稱：數據;這裏是它的URL：jdbc：mysql：// localhost：3306/data 我已經使用了驅動程序文件。 MySQL服務器實例正在運行。但它仍然無法正常工作。我找不到任何解決方案。請幫幫我。

我認爲你需要仔細看看你的第一行消息，它表示'訪問拒絕用戶'用戶'@'localhost'（使用密碼：YES）'。檢查您的憑據。 – 2013-12-16 19:28:06

由於OP似乎沒有讀取錯誤消息，因此此問題似乎是無關緊要的。 – 2013-12-16 19:28:57

http://dev.mysql.com/doc/refman/5.1/en/adding-users.html – CrazyCoder

java.sql.SQLException: Access denied for user 'user'@'localhost' (using password: YES)

檢查，這是否真的user存在於你的mysql/users表，並已加密的密碼？嘗試重新加載您的用戶數據庫權限。檢查mysql/db表中數據庫和該用戶的行。
