怎么在hibernate中通过联合主键更新表记录？

Question

<hibernate-mapping>
    <class name="com.yacol.hibernate.ProviderResource" table="provider_resource" catalog="yacol">
        <composite-id name="id" class="com.yacol.hibernate.ProviderResourceId">
            <key-property name="providerId" type="string">
                <column name="provider_id" length="12" />
            </key-property>
            <key-property name="resourceId" type="string">
                <column name="resource_id" length="12" />
            </key-property>
        </composite-id>
        <property name="totalScore" type="integer">
            <column name="total_score" />
        </property>
        <property name="environmentScore" type="short">
            <column name="environment_score" />
        </property>
        <property name="serviceScore" type="short">
            <column name="service_score" />
        </property>
        <property name="priceScore" type="short">
            <column name="price_score" />
        </property>
    </class>
</hibernate-mapping>

Answer 1

好像这样是不行
可以考虑用load和save方法

Answer 2

ProviderResourceId id = new ProviderResourceId();
id.setProviderId(mr.getProviderId());
id.setResourceId(mr.getResourceId());ProviderResource pr = hibernateSession.load(ProviderResource.class, id);
pr.setEnvironmentScore((int)totalEnvironmentScore);
...设置要更新属性, 省略
hibernateSession.save(pr);
