hibernate注解配置集合映射list

Question

set搞了一个上午，list弄了一下午了，注解都不知道怎么弄package gpf;import java.util.ArrayList;

@Test
public void save(){

husband.setName("丈夫1");
Wifes wifes1 = new Wifes();
Wifes wifes2 = new Wifes();
wifes1.setName("妻子1111111");
wifes2.setName("妻子2");
wifes1.setHusband(husband);
wifes2.setHusband(husband);
Session session = new AnnotationConfiguration().configure().buildSessionFactory().openSession();
session.beginTransaction();
session.save(wifes1);
session.save(wifes2);
session.getTransaction().commit();
}
}得到的number字段总是默认值0，不能排序啊，如何办呢

Answer 1

楼主太邪恶了，竟然能搞一夫多妻...
你那个存数据库的时候，number都没设值，肯定是默认的值0了啊。

Answer 2

嘿嘿，那要怎么配呢，xml中有个<list-index>,但是注解始终找不到方法哦

Answer 3

把Hibernate自动生成的SQL贴出来
如果有异常，把异常的栈 贴出来

Answer 4

我看半天不知道跟number 有什么关系啊！！LS要实现个什么东东啊
