Liferay的service.xml的外鍵許多到很多

Question

你好Liferay的專家，

請幫我創造一個Liferay的爲service.xml以下情形：

我有2個表

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> 
   

感謝

您可以創建表如下：

<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> 

我希望用戶_表正確映射這樣的...
