本文介绍了Java中的MySQL连接:用户@ localhost的访问被拒绝的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我无法连接到数据库,但我不知道为什么,因为用户名和密码正确,并且能够通过本地phpmyadmin进行连接.
I'm not able to connect to the Database but I don't know why, since the username and password are correct and I'm able to connect through phpmyadmin locally.
Class.forName("com.mysql.jdbc.Driver");
// Setup the connection with the DB
connect = DriverManager.getConnection(
"jdbc:mysql://localhost/yerobot", "yerobot", "yerobot123");
preparedStatement = connect.prepareStatement("select * from userdata");
resultSet = preparedStatement.executeQuery();
while(resultSet.next()){
// do read rs
}
每当我要求建立连接时,都会得到以下堆栈跟踪:
Whenever I call for a connection, I get this stacktrace:
java.sql.SQLException: Access denied for user 'yerobot'@'localhost' (using password: YES)

推荐答案
您需要同时设置yerobot @ localhost和yerobot @'%'的密码
You need to set the password for both yerobot@localhost and yerobot@'%'
MySQL区分本地访问密码和远程访问密码.
MySQL differentiates local access and remote access passwords.
