Liferay动态查询投影有两个字段

Question

我需要使用带有多个字段的带有Projection的动态查询。像这样的东西

DynamicQuery query = DynamicQueryFactoryUtil.forClass(Purchase.class);      query.add(PropertyFactoryUtil.forName("primaryKey.purchaseId,primaryKey.otherId").in(DynamicQueryFactoryUtil.forClass(ResponseField.class)          
                .add(PropertyFactoryUtil.forName("something").eq("something"))
                .setProjection(ProjectionFactoryUtil.property("primaryKey.purchaseId,primaryKey.otherId"))));

非常感谢提前！

您可以这样做：

ProjectionList projectionList = ProjectionFactoryUtil.projectionList();

projectionList.add(projection1);
projectionList.add(projection2);

dynamicQuery.setProjection(projectionList);
