Liferay service.xml外键多对多

你好，Liferay专家

请帮助我在Liferay中为以下场景创建

service.xml

：

我有两张桌子

SystemUsed

systemUsedId long
name varchar

userId long        --> mapped to userId of User_ table
systemUsedId long  --> mapped to  systemUsedId of SystemUsed table.<br>

用户使用的系统

systemUsedId long
name varchar

userId long        --> mapped to userId of User_ table
systemUsedId long  --> mapped to  systemUsedId of SystemUsed table.<br>

userId long-->映射到用户表的userId
systemUsedId long-->映射到SystemUsed表的systemUsedId。

谢谢

您可以按如下方式创建表：

<entity name="SystemUsed" local-service="true" remote-service="false"> 
    <column name="systemUsedId type="Long" />
    <column name="name" type="String"/>
</entity>
<entity name="User_SystemUsed" local-service="true" remote-service="false">  
    <column name="systemUsedId" type="SystemUsed" entity="SystemUsed" mapping-key="systemUsedId" />  
    <column name="userId" type="User" entity="User_" mapping-key="userid" />  
</entity>

您可以按如下方式创建表：

<entity name="SystemUsed" local-service="true" remote-service="false"> 
    <column name="systemUsedId type="Long" />
    <column name="name" type="String"/>
</entity>
<entity name="User_SystemUsed" local-service="true" remote-service="false">  
    <column name="systemUsedId" type="SystemUsed" entity="SystemUsed" mapping-key="systemUsedId" />  
    <column name="userId" type="User" entity="User_" mapping-key="userid" />  
</entity>
