spring, mysql, mybatis test

I'm testing using Spring, Mysql, MyBatis, but have some problems.
I run my application on tomcat. and my config files are below.

root-context.xml

        class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
    
    
    
    


    
    
    



    

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/sample
jdbc.username=player
jdbc.password=qwer1234!!

Controller and DAO is simple select.
When I call controller, exception occurs like this.

Caused by: java.sql.SQLException: Access denied for user
'player?€?'@'localhost' (using password: YES) at

import java.sql.PreparedStatement;
import java.sql.ResultSet;

import org.junit.Test;

public class MySqlTest {

    private final String DRIVER = "com.mysql.jdbc.Driver";
    private final String URL = "jdbc:mysql://127.0.0.1:3306/test";
    private final String USER ="player";
    private final String PW = "qwer1234!!";

    @Test
    public void test() {
        try{
        Connection connection = DriverManager.getConnection(URL, USER, PW); 
        PreparedStatement ps = connection.prepareStatement("select * from sample");
        ResultSet rs = ps.executeQuery();
        System.out.println(rs);
        } catch(Exception e){
            e.printStackTrace();
        }
    }
}
