Hibernate继承映射方式一

继承映射方式一：一个子类一张表 ，一张表对应一个配置文件

场景：父类person，子类student、teacher

Person.java

<br>Teacher.hbm.xml</p><p><textarea name="code" table="teacher_extend"&gt;&lt;id name="id" column="id" type="string"&gt;&lt;generator type="string"&gt;&lt;/property&gt;&lt;property name="salary" type="int"&gt;&lt;/property&gt;&lt;/class&gt;&lt;/hibernate-mapping&gt;测试类：

package com.fgh.hibernate;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.cfg.Configuration;public class ExtendMappingTest {private static SessionFactory sessionFactory;static {try {sessionFactory = new Configuration().configure().buildSessionFactory();} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {Session session = sessionFactory.openSession();Transaction tx = null;try {tx = session.beginTransaction();Student student = new Student();student.setName("zhangsan");student.setCardId("213421342");Teacher teacher = new Teacher();teacher.setName("lilaoshi");teacher.setSalary(4000);session.save(student);session.save(teacher);tx.commit();} catch (Exception e) {e.printStackTrace();if (null != tx) {tx.rollback();}} finally {session.close();}}}
