service - Liferay service.xml 外键多对多

Question

您好 Liferay 专家，

service.xml请帮我在 Liferay 中为以下场景创建一个：

我有 2 张桌子

1. SystemUsed
   

   systemUsedId long
   name varchar
   

2. User_SystemUsed
   

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

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>

我希望 user_ 表像这样正确映射......
