导包:

里面有struts的包  hiberdate里required里面所有的包，还有连接数据库的mysql包

1.配置***.hbm.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    <hibernate-mapping>
    <class name="cn.qyc.bean.Student" table="hibernatetext">
    <id name="id" column="id">
    <generator class="native"></generator>
    </id>
    <property name="name" column="name" type="string"></property>
    <property name="phone" column="phone" type="string"></property>
    </class>
    </hibernate-mapping>

2.配置hibernate.cfg.xml文件

所有配置信息http://www.yiidian.com/hibernate/hibernate-cfg-xml.html

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC  
        "-//Hibernate/Hibernate Configuration DTD//EN"  
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
    <hibernate-configuration>
    <session-factory>
    <property name="hibernate.dialect">
    org.hibernate.dialect.MySQLDialect
    </property>
    <property name="hibernate.connection.driver_class">
    com.mysql.jdbc.Driver
    </property>
    <property name="hibernate.connection.url">
    jdbc:mysql://localhost:3306/student
    </property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">123456</property>
    <property name="format_sql">true</property>
    <mapping resource="qyc.hbm.xml"/>
    </session-factory>
    </hibernate-configuration>

3.创建student的java bean

4.编写测试类

package hibernate3;

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

import cn.qyc.bean.Student;

public class Testhib {
	
	public void insert() {
		Configuration config = new Configuration().configure();
		SessionFactory sessionFactory = config.buildSessionFactory();
		Session session = sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();
		Student qycStudent  = new Student();
		qycStudent.setId(1);
		qycStudent.setName("强月城");
		qycStudent.setPhone("17635800128");
		session.save(qycStudent);
		transaction.commit();
		session.close();
		sessionFactory.close();
	}
	
	public void update() {
		Configuration config = new Configuration().configure();
		SessionFactory sessionFactory = config.buildSessionFactory();
		Session session = sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();
		Student qycStudent  = new Student();
		qycStudent.setId(2);
		qycStudent.setName("强成城");
		qycStudent.setPhone("1227694865");
		session.update(qycStudent);
		transaction.commit();
		session.close();
		sessionFactory.close();
	}
	
	public void select() {
		Configuration config = new Configuration().configure();
		SessionFactory sessionFactory = config.buildSessionFactory();
		Session session = sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();
		Student student = session.get(Student.class, 1);
		System.out.println(student.name);
		System.out.println(student.phone);
		transaction.commit();
		session.close();
		sessionFactory.close();
	}
	@Test
	public void delete() {
		Configuration config = new Configuration().configure();
		SessionFactory sessionFactory = config.buildSessionFactory();
		Session session = sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();
		Student student = new Student();
		student = session.get(Student.class, 2);
		session.delete(student);
		transaction.commit();
		session.close();
		sessionFactory.close();
	}
}

@Test放在要测试的方法前
