Question

我的 Thymleaf 页面中有以下表格：

  <div class="panel-body">

    <table class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>Issue Date</th>
                <th>Payment Schedule</th>
                <th>Total</th>
                <th>Status</th>
                <th>Start Date</th>
                <th>End Date</th>
                <th>Send Invoice</th>
            </tr>
        </thead>
        <tbody>
            <tr class="table-row" th:each="p : ${POList}">
                <td th:text="${p.issueDate}"></td>
                <td th:text="${p.paymentSchedule}"></td>
                <td th:text="${p.total}"></td>
                <td th:text="${p.status}"></td>
                <td th:text="${p.rentalPeriod.startDate}"></td>
                <td th:text="${p.rentalPeriod.endDate}"></td>

                <td>
                <form style='float:left; padding:5px; height:0px' th:object="${po}" th:method="post" th:action="@{'/dashboard/makeAndSendInvoice(email=${po.Email})'}">

                    <button class="btn btn-default btn-xs" type="submit">Send Invoice</button>
                </form>
                </td>
            </tr>
        </tbody>
    </table>
    </div>

我试图将po.Email的值发送给该方法。我想th:action="@{'/dashboard/makeAndSendInvoice(email=${po.Email})'}" 会创建dashboard/makeAndSendInvoice/{Email}

之类的链接

所以我试图在这样的方法中得到它：

 @RequestMapping(method=POST, path="makeAndSendInvoice")
    public String makeAndSendInvoice(@PathVariable("email") String email){

        System.out.println("Invoice is sent to..................."+email);
        return "Invoice";
    }

但在我看来它不起作用，因为它无法识别我的方法。那么如何在我的方法中接收po.Email

Answer 1

将th:action更改为：

th:action="@{/dashboard/makeAndSendInvoice/{email}(email=${po.Email})}"

并在PathVariable值中添加RequestMapping，如：

@RequestMapping(method=POST, path="/dashboard/makeAndSendInvoice/{email:.+}")
public String makeAndSendInvoice(@PathVariable("email") String email) {

来自Thymeleaf - Link URLs：

URL路径中也允许使用变量模板，例如 @{/order/{orderId}/details(orderId=${orderId})}

<!-- Will produce '/gtvg/order/details?orderId=3' (plus rewriting) -->
<a href="details.html" th:href="@{/order/details(orderId=${o.id})}">view</a>

<!-- Will produce '/gtvg/order/3/details' (plus rewriting) -->
<a href="details.html" th:href="@{/order/{orderId}/details(orderId=${o.id})}">view</a>

来自Spring - URI Template Patterns：

在Spring MVC中，您可以在方法上使用@PathVariable注释将其绑定到URI模板变量的值的参数：
@RequestMapping(value="/owners/{ownerId}", method=RequestMethod.GET)
public String findOwner(@PathVariable String ownerId, Model model) {
  Owner owner = ownerService.findOwner(ownerId);
  model.addAttribute("owner", owner);
  return "displayOwner";
}
