我正在尝试编写一个连接到 MySQL 数据库的 java 程序。但我收到此错误:

找不到适合 jdbc:mysql//localhost:3306/test 的驱动程序

我已经安装了mysql-connector-java.5.1.23-bin.jar. 我仍然收到此错误。

这是我的程序:

package database_practice;

import java.sql.*;

public class CreateConnection {
        private Connection conn = null;

        public static void main(String args[]) {
            CreateConnection conn = new CreateConnection();
                conn.getConnection();
        }


        public Connection getConnection() {
            try {
                String url = "jdbc:mysql//localhost:3306/test";
                String username = "root";
                String password = "admin1234";

            Class.forName("com.mysql.jdbc.Driver").newInstance();
            conn = DriverManager.getConnection(url, username, password);
            System.out.println("Database Created...!!!");
        }

        catch (Exception e) {
            e.printStackTrace();
            System.out.println("Error occured while connecting to database");
        }
            return conn;
    }
}

您的连接字符串错误。这:

"jdbc:mysql//localhost:3306/test"

应该:

"jdbc:mysql://localhost:3306/test"

注意“”后面的冒号mysql
