我收到以下错误
Access denied for user 'Admin'@'localhost (using password: YES)
每次我尝试从 java 代码连接时,我都创建了一个新用户并授予了完全权限,但我仍然得到同样的错误。
下面是用于从 java 连接的代码
String userName = "svp01m";
String password = "svp01m";
String url = "jdbc:mysql://localhost/project";
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url, userName, password);
错误信息
java.sql.SQLException: Access denied for user 'admin'@'localhost' (using password: YES
