Question

我们有以下代码：

<div th:each="client : ${clients}">
    <div th:each="purchase : ${client.purchases}">
        <div th:each="product : ${purchase.products}">
            <span th:text="${product.price}"></span>
            <!-- <span id="2" th:text="${#aggregates.sum(products.{price})}"> </span> -->
            <!-- <span id="2" th:text="${#aggregates.sum(products.![price])}"> </span>  -->
        </div>
    </div>
</div>

输出结果为：

5.25
4.20

如果我取消注释第一条评论，我会收到错误

Exception evaluating SpringEL expression: "#aggregates.sum(products.{price})" (clients/clients:84)

如果我只取消注释第二条评论，我会收到错误：

Exception evaluating SpringEL expression: "#aggregates.sum(products.![price])" (clients/clients:85)

我尝试使用http://demo-dspace-cris.cineca.it/bitstream/123456789/26/1/usingthymeleaf.pdf

我正在使用thymeleaf 2.1.4

IT工作！

我应该使用：

<span id="2" th:text="${#aggregates.sum(purchase.products.![price])}"> </span>

Answer 1

我在发布后自己想出来了！

<div th:each="client : ${clients}">

            <div th:each="purchase : ${client.purchases}">
                <span id="2"
                    th:text="${#aggregates.sum(purchase.products.![price])}"> </span>
                <div th:each="product : ${purchase.products}">
                    <span th:text="${product.price}"></span>

                </div>
            </div>
        </div>

输出：

9.45
5.25
4.20
