访问被拒绝从 java 连接到 mysql

Question

我正在尝试从 java 连接到数据库并收到以下错误消息：

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

但我正在连接的命令行使用相同的凭据

server$ mysql -ugda -pgda

在另一个数据库上，我的 java 工作正常并且能够连接。似乎是数据库级别的问题？！我需要在数据库级别修复什么？

添加连接代码：

public Connection getConnection() {     
    try {
        Class.forName(jdbcDriver);

        connection = DriverManager.getConnection(connectionString());
    }
    catch(Exception ex) {
        ex.printStackTrace();
        logger.error("Exception:" + ex.getMessage());
        errorMessage = ex.getMessage();
    }

    return connection;
}

地点：

jdbc:mysql://127.0.0.1:3306/db?user=gda&password=gda

Answer 1

尝试以这种方式传递用户名和密码：

String DB_URL = "jdbc:mysql://localhost/xyz";
String USER = "username";
String PASS = "password";

conn = DriverManager.getConnection(DB_URL,USER,PASS);
