Question

<class name="com.hp.wap.soothsaying.obj.ZbBloodItem"  table="ZB_Blood_Item" catalog="HappyPlay">
<id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="increment" />
        </id>    <set name="items"  cascade="all,delete-orphan" >
    <key column="item_id"/>
    <one-to-many  class="xxxxxxxxxxxxxxxxxxxxItem" />
</set>同时你的ZbBloodItem中有一个
private Set<Item> items;
set...

Answer 1

<key column="item_id"/> 
它指的是另一个表中的字段吗？

Answer 2

<hibernate-mapping>
    <class name="Like" table="like" schema="dbo" catalog="teststruts">
        <id name="lid" type="java.lang.Integer">
            <column name="lid" />
            <generator class="identity" />
        </id>
        <property name="lname" type="java.lang.String">
            <column name="lname" length="50" />
        </property>
        <set name="likechild" inverse="true">
            <key>
                <column name="lid" not-null="true" />
            </key>
            <one-to-many class="Likechild" />
        </set>
    </class>
</hibernate-mapping>
