spring - 带有来自 thymeleaf 的路径变量的多个请求映射值

Question

我必须从 thymeleaf 发送两个数据至 controller像这样在a th:href :

<table id="itemTable" class="deneme">
    <tbody>
    <tr th:each="item : ${list.items}">
        <td>
            <p th:text="${item.content}"/>
            <a th:href="@{/deleteItem/{listId}(listId=${list.id})/{itemId}(itemId=${item.id})}">
                <span>Delet‌​e</span>
            </a>
        </td>
    </tr>
    </tbody>
</table>

Controller 是:

@RequestMapping("/deleteItem/{listId}/{itemId}")
public String deleteItem(Model model, @PathVariable(value = "listId") Integer listId, @PathVariable(value = "itemId") int itemId) {
    ...
    return "list";
}

itemId带有真正的值(value)，但 listId即将到来 {listId}(listId=${toDoList.id})
究竟是什么问题？请帮我!

Answer 1

多个参数的语法如下所示:

<a th:href="@{/deleteItem/{listId}/{itemId}(listId=${list.id},itemId=${item.id})}"><span>Delet‌​e</span></a>
