Я использую построители услуг для создания новых объектов в моем liferay 6.1 hook. Я хочу создать много-много отношений между одним из моих пользовательских объектов и пользовательской сущностью портала. Так что я сделал следующее:Взаимосвязь между настраиваемым сущностью и пользовательским объектом в перехватах
<entity name="MyEntity" local-service="true" remote-service="true">
<column name="myEntityId" type="long" primary="true"></column>
<column name="users" type="Collection" entity="com.liferay.portal.User" mapping-table="Users_Garages"></column>
<reference entity="User" package-path="com.liferay.portal"></reference>
</entity>
Однако, когда я строю мой строитель службы я получаю следующее исключение:
Method public java.util.List com.liferay.portal.tools.servicebuilder.ServiceBuilder.getMappingEntities(java.lang.String) throws java.io.IOException threw an exception when invoked on [email protected]
The problematic instruction:
----------
==> list serviceBuilder.getMappingEntities(column.mappingTable) as mapColumn [on line 260, column 41 in com/liferay/portal/tools/servicebuilder/dependencies/model_impl.ftl]
----------
Java backtrace for programmers:
----------
