Answer 2

org.hibernate.TransientObjectException: com.sshshop.entity.UserInfo TransientObjectException 
异常1：not-null property references a null or transient value 
解决方法：将“一对多”关系中的“一”方，not-null设置为false 
（参考资料：http://www.thearcmind.com/confluence/pages/viewpage.action?pageId=212） 异常2：org.hibernate.TransientObjectException: object references an unsaved transient instance 
解决方法：cascade="save-update,persist" 
（参考资料：http://www.laliluna.de/254.html） 异常3：org.hibernate.QueryException: could not resolve property 
解决方法："from Category category where category.userID = :userID"修改为"from Category category where userID = :userID"或者"from Category category where category.user.id = :userID" 
（参考资料：http://www.laliluna.de/277.html） 异常4：could not initialize proxy - the owning Session was closed 
解决方法：设置lazy为false 
（参考资料：http://forum.springframework.org/showthread.php?t=27993） <many-to-one name="userInfo" class="com.sshshop.entity.UserInfo" fetch="select" cascade="save-update" >
            <column name="UserID" not-null="false"  /> 
        </many-to-one> 这只是初步判断。最好把抛异常的方法给贴出来。

Answer 3

异常抛出的方法：
public Serializable save(Object entity) throws Exception {



return  this.getHibernateTemplate().save(entity);
}
我是把collectionsbean传进去的
cartbean.setProduct(product);
userbean.setLoginName(username);
cb.setProduct(product);
cb.setUserInfo(userbean);
if (collectionbiz.SelectCollections(cb,page).size()==0) { Serializable pk=collectionbiz.saveCollections(cb, userbean);}
这里是调用

Answer 4

<hibernate-mapping> 
    <class name="com.sshshop.entity.Collection" table="Collection" schema="dbo" catalog="TShop" lazy="false"> 
        <id name="id" type="java.lang.Integer"> 
            <column name="ID" /> 
...<many-to-one name="userInfo" class="com.sshshop.entity.UserInfo" fetch="select" cascade="save-update" > 
    <column name="UserID" not-null="false"  /> 
</many-to-one>...
...

Answer 5

我这样应该是根据user来保存collectionbean 吧，但是他为什么会先插入个user呢，我user是有的，也就是说是游离的,是不是不应该用save，而是用update 呢

Answer 6

user是啥，如果是表名，最好别用
可以使用saveorupdate，
估计你存的时候，参数个数什么的或类型什么的出现问题了
