Первый Hibernate класс, имеющий Аннотация

Question

Image contains the JARS files which I already have. Это мой hibernate.cfg.xml файл

<?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> 

Это мой DTO класс

package com.app.hibernate; 

import java.io.Serializable; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name = "paytm_table") 

public class PaytmDTO implements Serializable 
{ 
    @Id 
    @Column(name="mob_num") 
    private int mobileNumber; 

    @Column(name="amount") 
    private int amount; 

    @Column(name="email_id") 
    private String emailId; 

    @Column(name="OTP") 
    private int OTP; 

    public PaytmDTO() { 

    } 

    public int getMobileNumber() { 
     return mobileNumber; 
    } 

    public void setMobileNumber(int mobileNumber) { 
     this.mobileNumber = mobileNumber; 
    } 

    public int getAmount() { 
     return amount; 
    } 

    public void setAmount(int amount) { 
     this.amount = amount; 
    } 

    public String getEmailId() { 
     return emailId; 
    } 

    public void setEmailId(String emailId) { 
     this.emailId = emailId; 
    } 

    public int getOTP() { 
     return OTP; 
    } 

    public void setOTP(int oTP) { 
     OTP = oTP; 
    } 

} 

Это мой класс DAO

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(); 

    } 

} 

И Я получаю эти ошибки в консоли

Пожалуйста, объясните мне, где мне не хватает? Мое имя пользователя и пароль пользователя root. Это моя первая программа Hibernate, а также я вставляю все баночки под свою библиотеку, а также выполняет buildPath.

Answer 1

Это говорит довольно ясно

Вызванный: java.sql.SQLException: Нет подходящий драйвер не найден ...

Вы, вероятно, отсутствует библиотека соединителя MySQL. Если вы используете Maven, добавьте

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

к вашему pom.xml. Если нет, вы можете загрузить .jar от here
