假设我已经在html模板上呈现了get请求的输出,现在我需要使用相同的数据通过同一页面上的按钮传递给post请求.我怎么做？
我正在尝试做这样的事情：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<title>Customer Home</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div th:replace="fragments/header :: header">
</div>
<div class="container">
<p> Thanks for booking with Gamma Airlines,here are your booking summary: </p>
<table th:object="${booking} class="table table-bordered table-striped">
<tbody>
<tr>
<td>Source</td>
<td th:text="${routeStart}"></td>
</tr>
<tr>
<td>Destination</td>
<td th:text="${routeDestination}"></td>
</tr>
<tr>
<td>Booking Charges</td>
<td th:text="${bookingCharges}"></td>
</tr>
<tr>
<td>Booking Charges Currency</td>
<td th:text="${chargesCurrency}"></td>
</tr>
<tr>
<td>Booking Date</td>
<td th:text="${#calendars.format(bookingDate)}">July 11,2012 2:17:16 PM CDT</td>
<tr>
<td>
<div class="col-sm-9">
<form action="#" th:action="@{/email}"
th:object="${booking}" method="post"
role="form">
<button type="submit" class="btn btn-primary btn-block">Email</button>
</form>
</div>
</td>
<td>
<div class="col-sm-9">
<form action="#" th:action="@{/genpdf}"
th:object="${booking}" method="post"
role="form">
<button type="submit" class="btn btn-primary btn-block">Generate PDF</button>
</form>
</div>
</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
编辑：有人请帮我告诉我一个传递对象的简单方法,因为我必须在很多地方使用它,并且在某些情况下对象包含许多子对象.例如.以下情况：
<div style = "margin-top: 2cm" class="container">
<table class="table table-bordered table-striped">
<thead>
<tr>
<td>Source</td>
<td>Destination</td>
<td>Amount</td>
<td>Currency</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr th:if="${offers.empty}">
<td colspan="5">No Offers</td>
</tr>
<tr th:each="offer : ${offers}">
<td th:text="${offer.route.from}"></td>
<td th:text="${offer.route.to}"></td>
<td th:text="${offer.price.amount}"></td>
<td th:text="${offer.price.currency}"></td>
<td>
<form action="#" th:action="@{/user/booking}"
th:object="${offer}" method="post"
role="form">
<button type="submit" class="btn btn-primary btn-block">Book</button>
</form>
</td>
</tr>
</tbody>
</table>
</div>
更新2：
我甚至通过在get请求中发送一个新对象来更改模板,并尝试逐个分配值,但我仍然在控制器中将其作为null.
<table class="table table-bordered table-striped">
<thead>
<tr>
<td>Source</td>
<td>Destination</td>
<td>Amount</td>
<td>Currency</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr th:if="${offers.empty}">
<td colspan="5">No Offers</td>
</tr>
<tr th:each="offer : ${offers}">
<td th:text="${offer.route.from}"></td>
<td th:text="${offer.route.to}"></td>
<td th:text="${offer.price.amount}"></td>
<td th:text="${offer.price.currency}"></td>
<td>
<form action="#" th:action="@{/user/booking}"
th:object="${booking}" method="post"
role="form">
<input type="hidden" th:attr="value = ${offer.route.from}" th:field="*{routeStart}" />
<input type="hidden" th:attr="value = ${offer.route.to}" th:field="*{routeDestination}" />
<input type="hidden" th:attr="value = ${offer.price.amount}" th:field="*{bookingCharges}" />
<input type="hidden" th:attr="value = ${offer.price.currency}" th:field="*{chargesCurrency}" />
<button type="submit" class="btn btn-primary btn-block">Book</button>
</form>
</td>
</tr>
</tbody>
</table>
这些是我的get和post方法：
@RequestMapping(value="/user/booking",method = RequestMethod.GET)
public ModelAndView getoffers()
{
ModelAndView modelAndView = new ModelAndView();
AirlineOffer[] offersArray= airlineClient.getoffers();
List<AirlineOffer> offers = Arrays.asList(offersArray);
modelAndView.addobject("offers",offers);
Booking booking = new Booking();
modelAndView.addobject("booking",booking);
modelAndView.setViewName("user/booking");
return modelAndView;
}
/** POST method for submitting deposit request */
@RequestMapping(value = "/user/booking",method = RequestMethod.POST)
public ModelAndView book(@Valid Booking booking,BindingResult bindingResult,HttpServletRequest request)
{
ModelAndView modelAndView = new ModelAndView();
......
}
解决方法
好吧,我终于在我的表单中使用以下内容解决了它：
<table class="table table-bordered table-striped">
<thead>
<tr>
<td>Source</td>
<td>Destination</td>
<td>Amount</td>
<td>Currency</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr th:if="${offers.empty}">
<td colspan="5">No Offers</td>
</tr>
<tr th:each="offer,stat : ${offers}">
<td th:text="${offer.route.from}"></td>
<td th:text="${offer.route.to}"></td>
<td th:text="${offer.price.amount}"></td>
<td th:text="${offer.price.currency}"></td>
<td>
<form action="#" th:action="@{/user/booking}"
th:object="${booking}" method="post"
role="form">
<input type="hidden" th:value="${offer.route.from}" name="routeStart" />
<input type="hidden" th:value = "${offer.route.to}" name="routeDestination" />
<input type="hidden" th:value = "${offer.price.amount}" name="bookingCharges" />
<input type="hidden" th:value = "${offer.price.currency}" name="chargesCurrency" />
<button type="submit" class="btn btn-primary btn-block">Book</button>
</form>
</td>
</tr>
</tbody>
