Answer 2

你执行什么操作的时候出错的，java代码；
很明显shopId字段没产生啊，你什么数据库，是否支持identity类型

Answer 3

我用的sqlserver.支持identity

Answer 4

public void addShop(Shop shop) {
getHibernateTemplate().save(shop); //这行出错..

}

Answer 5

 <property name="shopTypeId" type="int"/><!--这行去掉 -->
 <many-to-one name="shopClass" column="ShopTypeId" class="com.bank.bean.ShopType" lazy="false"/> <!--这里已经有个ShopTypeId-->

Answer 6

嗯嗯。。我去掉了。。但是保这个错..org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.bank.bean.ShopType

Answer 7

在ShopType表中确定有你所引用的外键的值

Answer 8

他说什么未瞬态实例。。但我我已经Shop s = new Shop();啦。。
public void addShop(Shop shop) {
Shop s = new Shop();
System.out.println(shop.getShopTypeId());
//s.setShopTypeId(shop.getShopTypeId());
s.setShopName(shop.getShopName());
s.setShopPrice(shop.getShopPrice());
s.setShopStock(shop.getShopStock());
s.setShopScores(shop.getShopScores());
s.setShopTime(new Date());
s.setShopPicture(shop.getShopPicture());
dao.addShop(s);
}

Answer 9

你要把shopType先save了，再save shop

Answer 10

但我shopType不用插入数据,,,shop才要...那我要插什么数据进去??/

Answer 11

主要是外键引用的问题，你保证你的shopType的ID是已经存入数据库的就OK

Answer 12

shoptype那ID已经在数据库,,,我只是把shop的数据存进去..

Answer 13

<many-to-one name="shopClass" column="ShopTypeId" class="com.bank.bean.ShopType" lazy="false" cascade="save-update,persist"/>
试试

Answer 14

这样做的话。。shopType这边的数据也会插入,,,!

Answer 15

我只想保存一张表呢...呵呵..!!shopType只是关联关系..一般很少插入数据.,..除非是添加类型. 

Answer 16

我就觉得你没有把shopType存入新插入的shopType数据有重复没？

Answer 17

shopType
11 NULL NULLshop
29 11 EVO4Gshop的外键我是想把页面上选中的id插进去shop表里..不是插到shopType里.

Answer 18

你引用的那个对象的ID设成你shopType表里面有的。
shopType.getId()//这个值必须已经存在数据库中
shop.setShopType(ShopType);

Answer 19

insert into Shop (shopTypeId, shopName, shopPrice, shopStock, shopScores, shopTime, shopPicture, ShopTypeId) values (?, ?, ?, ?, ?, ?, ?, ?)]
这里面不是两个shopTypeId 吗？不是说你插进2个相同的字段么？第一个和最后一个 这两个字段不是名字一样么 都是shopTypeId
