Mysql 具有注释的第一个Hibernate类

这是我的hibernate.cfg.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>
        <property name="connecton.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate_db</property>
        <property name="show_sql">true</property>
    </session-factory>
</hibernate-configuration>

这是我的刀课

package com.app.hibernate;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class PaytmDAO 
{
    public static void main(String[] args) 
    {
        //Create Object of DTO
        PaytmDTO dto=new PaytmDTO();

        //Set the DTO values using Setter method
        dto.setAmount(239);
        dto.setEmailId("impriyank95@gmail.com");
        dto.setMobileNumber(941478859);
        dto.setOTP(8965);

        //Create Object of Configuration
        Configuration config=new Configuration();
        config.configure();
        config.addAnnotatedClass(PaytmDTO.class);

        //Create object of 2nd Component SessionFactory
        SessionFactory sf=config.buildSessionFactory();

        //Get a Session (3rd Component)
        Session sess=sf.openSession();
        sess.save(dto);

        Transaction tx=sess.beginTransaction();
        tx.commit();

    }

}

我在控制台中得到了这些错误

请解释一下我缺少什么？我的数据库用户名和密码是root。这是我的第一个Hibernate程序，而且我已经将所有JAR粘贴到了我的lib下，还完成了buildPath。

它说得很清楚

您可能缺少MySQL连接器库。如果您使用的是maven，请添加

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.5</version> <!-- or whatever version is suitable -->
    <scope>runtime</scope>
</dependency>

mysql
**我添加了MySQL连接器。我已将添加的JAR附加到lib文件夹下。**我已添加JAR的图像。请看一看。
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.5</version> <!-- or whatever version is suitable -->
    <scope>runtime</scope>
</dependency>
