实体类
package com.tao.pojo;
public class Student {
    
    private String id;
    private String name;
    private String pass;
    
    public Student() {
        super();
    }
    public Student(String name, String pass) {
        super();
        this.name = name;
        this.pass = pass;
    }
    public Student(String id, String name, String pass) {
        super();
        this.id = id;
        this.name = name;
        this.pass = pass;
    }
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPass() {
        return pass;
    }
    public void setPass(String pass) {
        this.pass = pass;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", pass=" + pass + "]";
    }
}

测试
package com.tao.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.dialect.MySQL5Dialect;

public class TestMain {
    //用hibernate框架创建表
    public static void main(String[] args) {
        Configuration configure = new Configuration().configure("hibernate.cfg.xml");
        SessionFactory factory = configure.buildSessionFactory();
        Session session = factory.openSession();
        session.beginTransaction();
        
        session.getTransaction().commit();
        session.close();
        factory.close();
        
    }
}

用程序生成表，如果报的有这个错
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'type=MyISAM' at line 6
解决方案
将数据库方言改为
 <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
