我有一个ArrayList数组ArrayList<[obj1,obj2]>。这里的obj1和obj2是不同的Java实体，这个列表是由HQL查询返回的。
如何在struts.xml文件中循环遍历此列表以将其作为JSON结果发送？
我尝试了下面的组合，但没有运气：

1. ^itemList\[\d+\]\.^\[\0+\].id--> id是实体的属性
2. ^itemList\[\d+\]\.\0\.id
3. ^itemList\[\d+\]\.co.id--> co = hql中的实体别名
4. ^itemList\[\d+\]\[0].id
5. ^itemList\[\d+\]\.\[\0+\].id
6. ^itemList\[\d+\]\.[0].id

我在struts.xml中使用它如下：

<action name="list-view-op-cost-management_cons"  class="com.eves.aixis.s2.action.billing.ConsignmentBillingGridAction" method="listViewOperationalCostForManagement">
            <result type="json">
                <param name="ignoreHierarchy">false</param>
                <param name="includeProperties">
                    viewType,
                    searchType,
                    searchValue,
                    service,
                    page,
                    total,
                    records,
                    ^itemList\[\d+\]\.^\[\0+\].id,
                    reqaction_,
                    actionResult,
                    ^errorList\[\d+\]
                    
                </param>
            </result>
        </action>

Obj1 = Consignment(Bussiness entity)
