Question

我在显示列表订单时遇到重复行的问题，该列表订单列出了具有一对多关联的项目。订单将重复订单中的商品数量，而不是每个订单的一次。

这是我的代码...... 控制器映射

<div>
Delivery
<table class="orders">
    <tr>
        <td>Order #</td>
        <td>Name</td>
        <td>Phone Number</td>
        <td>Street</td>
        <td>Items</td>
        <td>Total</td>
    </tr>

    <c:forEach var="deliveryKitchen" items="${deliveryKitchen}">
        <tr>
            <td><c:out value="${deliveryKitchen.idorders}"></c:out></td>
            <td><c:out value="${deliveryKitchen.users.name}"></c:out></td>
            <td><c:out value="${deliveryKitchen.users.phoneNo}"></c:out></td>
            <td><c:out value="${deliveryKitchen.addresses.street1}"></c:out>

    <td>
    <c:forEach var="insideItems" items="${deliveryKitchen.orderitem}">

            <c:out value="${insideItems.items.name}"></c:out>

    </c:forEach>

尝试一下：

Criteria crit = session().createCriteria(Orders.class);
crit.createCriteria("status", "c");
crit.add(Restrictions.eq("c.idstatus", 2));
crit.setResultTransformer(CriteriaSpecification.DISTINCT_ROOT_ENTITY);
