但是在插入的时候报错

我不知道是什么原因

测试代码是这样的

Author author = new Author();
author.setId(2);
author.setName("byh");
Topic topic = new Topic();
topic.setId(2);
topic.setName("g");
topic.setAuthor(author);
sess = HibernateUtil.currentSession();
tx = sess.beginTransaction();
sess.save(topic);
tx.commit();

请哪位大侠给予帮助！我的msn是yunhengbai@hotmail.com
