解决org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade

今天学hibernate多对一双向关联要删除多的一方时，我在两个持久类中都设了cascade=CascadeType.ALL，由于只想要删除一条记录，而与之相关联的其他记录不想被删除，所以我用了以下方法（多个Person对应一个Address）：

Person p1 = (Person)session.get(Person.class, 3);
    p1.setAddress(null);
    session.delete(p1);

但是会给我提示错误 [org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations)][org.hibernate.ObjectDeletedException_ deleted object would be re-saved by cascade _remove deleted object from associations]

经过几次修改实验解决了：

Person p1 = (Person)session.get(Person.class, 4);
    p1.getAddress().getPersons().remove(p1);
    p1.setAddress(null);
    session.delete(p1);
