測試文件：
public class Test {
@org.junit.Test
public void testAdd() {
SessionFactory sf = HibernateUtil.getSessionFactory();
Session session = sf.getCurrentSession();
session.beginTransaction();
Wife wife = new Wife();
wife.setName("wife");
Husband husband = new Husband();
husband.setName("husband");
husband.setWife(wife);
session.save(wife);
session.save(husband);

測試結果：
Hibernate: insert into Wife (name) values (?)
Hibernate: insert into Husband (name, wid) values (?, ?)
