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

I am connecting Java using Eclipse with MySQL db

CODE

import java.sql.*;
import java.io.*;

public class DbDemo {

    public static void main(String args[]) throws ClassNotFoundException, SQLException {

        String s;       
        String uname="root@localhost";
        String url="jdbc:mysql://localhost:3306/student";

        String password="Hsun123";

        int i;

        try {

            Class.forName("com.mysql.jdbc.Driver").newInstance();

            Connection con=DriverManager.getConnection(url,uname,password);

            Statement st=con.createStatement();

            ResultSet rs=st.executeQuery("select * from student_detail");

            if(rs.next()) {

                i=rs.getInt(1);

                s=rs.getString(2);

                System.out.println(i+"/t"+s);
            }           

            rs.close();

            st.close();

            con.close();

        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

Choose a password like password = 'Hellobds123@S'

Then run

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Hellobds123@S';

FLUSH PRIVILEGES;

My answer with the new connector for a data base myPhpAdmin :

spring.datasource.url= jdbc:mysql://localhost:8889/mydb?serverTimezone=UTC
spring.datasource.username= root
spring.datasource.password= root
spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver
spring.jpa.show-sql= false
spring.jpa.hibernate.ddl-auto= update
#spring.jpa.hibernate.ddl-auto= create
spring.jpa.properties.hibernate.dialect= org.hibernate.dialect.MySQL5Dialect
spring.main.banner-mode= off

Late answer, but findings can help others :) Faced similar issue, i was trying to connect database from Spring boot application developed using Eclipse. Open Mysql Command Prompt or GUI tool and run following query.

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '%your_password%' WITH GRANT OPTION;

Also check your TCP/IP service for database are enabled or not.

For those who are suffering from this problem

java.sql.SQLException: Access denied for user 'root'@'localhost'

(using password: YES)

Solution for that is:

Whatever password you are providing on this line in your code 

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

No need to provide this password just insert ""

Complete Code is:

import java.sql.*;  
class TestDB{  
    public static void main(String args[]){  
    try{  
        Class.forName("com.mysql.jdbc.Driver");  
        Connection con=DriverManager.getConnection(         "jdbc:mysql://localhost:3306/Pravin","root","");  
        //here sonoo is database name, root is username and password  
        Statement stmt=con.createStatement();  
        ResultSet rs=stmt.executeQuery("select * from student");  
        while(rs.next())  
            System.out.println(rs.getInt(1)+"  "+rs.getString(2)+" "+rs.getString(3));  
        con.close();  
    }catch(Exception e){
        System.out.println(e);  
    }  
}

If you are connecting a remote mysql server from your local machine using java see the below steps.

Error : java.sql.SQLException: Access denied for user 'xxxxx'@'101.123.163.141' (using password: YES)

for remote access may be cPanel or others grant the remote access for your local ip address.

In the above error message: "101.123.163.141" is the local machine IP. So First we have to give remote access in the cPanel-> Remote MySQL®. Then run your application to connect.

Class.forName("com.mysql.jdbc.Driver");  
Connection con=DriverManager.getConnection(  
    "jdbc:mysql://www.xyz.com/abc","def","ghi");  
//here abc is database name, def is username and ghi        
Statement stmt=con.createStatement();  
ResultSet rs=stmt.executeQuery("select * from employee");  
    while(rs.next())  
        System.out.println(rs.getInt(1)+" "+rs.getString(2)+"  
                      "+rs.getString(3));  
con.close();

Hope it will resolve your issue.

Thanks

Make sure you have a privileged (i.e. neccessary rights) user account with correct password exist in your database. or just creat no password at all

Well, same problem here. I'm using phpmyadmin.

I had to go to phpmyadmin->users->root->Edit Privileges.

Then on the field "Database-specific privileges" I had to provide privileges for my database.

On the field "Change password" I retyped my password (I don't know why I had to do that, maybe a possible bug since i already had one).

On the field "Login Information->Host" I put value Any host.

Problem is solved.

Instead of using :

 String uname="root@localhost";

Use :

String url="jdbc:mysql://localhost:3306/student";
String userName="root"
String password="Hsun123"
...
try{

        Class.forName("com.mysql.jdbc.Driver").newInstance();

        Connection con=DriverManager.getConnection(url,username,password);
...

This should work (provided you are setting the valid password)
