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 + "]";
}
} 映射文件

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>
