Question

我正在尝试在3个表之间创建关系。以下是表格：

间
设施
facilityMapping

房间表包含

roomId
ROOMNAME

设施表包含

facilityId
facilityName

facilityMapping表包含

facilityId
roomId
facilityQuantity

在facilityMapping表中，我想创建对上面两个表的引用。

在service.xml中，我正在尝试创建Reference

<service-builder package-path="com.admin.services">
    <namespace>rbms</namespace>
    <entity name="rooms" local-service="true" remote-service="false">
        <column name="roomId" type="int" primary="true"></column>
        <column name="roomName" type="String"></column>
        <column name="roomFloorNo" type="int"></column>
        <column name="roomLocationName" type="String"></column>
        <column name="roomCapacity" type="int"></column>
        <column name="roomImages" type="String"></column>
    </entity>
    <entity name="facilities" local-service="true" remote-service="false">
        <column name="facilityId" type="int" primary="true"></column>
        <column name="facilityName" type="String"></column>
        <!-- 
         |- Finding Equipments using their Names and display it in form 
         |- It will help you to add new Room.
        -->
        <finder name="facilityName" return-type="Collection">
            <finder-column name="facilityName"></finder-column>
        </finder>
    </entity>
    <entity name="facilityMapping" remote-service="false" local-service="true">
        <column name="facilityId" type="int"></column>
        <column name="roomId" type="int"></column>
        <column name="facilityQuantity" type="int"></column>
        <column name="fk_fid" type="Collection" entity="com.admin.services.facilities" mapping-key="facilityId"></column>
    </entity>
</service-builder>

错误：必须为元素类型列声明mapping-key

Answer 1

由于在新的Liferay版本中不推荐使用mapping-key，因此我使用mapping-table属性完成工作
