我正在eclipse中制作一个简单的雇员测试文件。但它显示了一个错误，即无法获取jdbc连接。请帮帮我。
错误是

Could not get JDBC Connection; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Client does not support authentication protocol requested by server; consider upgrading MySQL client

xmlfile是

<?xml version="1.0" encoding="UTF-8"?>
<bean
    class="org.springframework.jdbc.datasource.DriverManagerDataSource"
    name="dataSource" p:driverClassName="com.mysql.jdbc.Driver"
    p:url="jdbc:mysql://localhost/mydb" p:username="root"
    p:password="banjit" />
<bean class="org.springframework.jdbc.core.JdbcTemplate"
    name="jdbcTemplate" p:dataSource-ref="dataSource" />

java代码是

public class Test {
    public static void main(String[] args) {
        ApplicationContext context =new ClassPathXmlApplicationContext("com/banjit/spring/springjdbc/refconfig.xml");
        JdbcTemplate jdbcTemplate = (JdbcTemplate) context.getBean("jdbcTemplate");
        String sql = "insert into employee values (?,?,?)";
        int result = jdbcTemplate.update(sql, new Integer(1), "Banjit","Das");
        System.out.println("Numbers of records inserted  "+result);
    }
}
