Question

我正在尝试将JDBC项目从Eclipse连接到MySQL。我不断收到相同的错误消息：

com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException：客户端不支持服务器请求的身份验证协议；考虑升级MySQL客户端

在以下代码行上：

Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/WorldFootball","root","");

WorldFootball是我在MySQL中创建的数据库

我正在使用最新版本的MySQL版本8.0.16

下面是我的完整Java代码

import java.sql.*;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.Connection;

public class SQL {

public static void main(String[] args) throws InstantiationException, 
IllegalAccessException, ClassNotFoundException {
    // TODO Auto-generated method stub

    try {

        String Driver = "com.mysql.jdbc.Driver";
        Class.forName(Driver);
        Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/WorldFootball","root","");
            Statement stmt=con.createStatement();
            String sql ="SELECT * FROM PremierLeague";
            ResultSet rs=stmt.executeQuery(sql);
            if (rs.next()){
                System.out.println("Too Sweet");
            }
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

需要JDBC连接帮助
