问题描述
我试图做这样的事情：
<！DOCTYPE html>
< html xmlns =http://www.w3.org/1999/xhtml
xmlns：th =http://www.thymeleaf.org>
< head>
< title>客户主页< / title>
< link rel =stylesheethref =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>感谢您与Gamma Airlines的预订，以下是您的预订总结：< / p>
< table th：object =$ {booking} class =table table-bordered table-striped>
< tbody>
< tr>
< tr> ; td>来源< / td>
< td th：text =$ {routeStart}>< / td>
< / tr>
< tr>
< td>目的地< / td>
< td th：text =$ {routeDestination}>< / td>
< / tr>
< ; tr>
< td>预订费用< / td>
< / tr>
< td th：text =$ {bookingCharges}>< / td>
< tr>
< td>预订费用货币< / td>
< td th：text =$ {chargesCurrency}>< / td>
< / tr>
< tr>
< td>预订日期< / td>
< td th：text =$ {＃calendars.format（bookingDate）}> 2012年7月11日下午2:17:16 CDT< / td>
< tr>
< td>
< div class =col-sm-9>
< form action =＃th：action =@ {/ email}
th：object =$ {booking}method =post
role =form >
< button type =submitclass =btn btn-primary btn-block>电子邮件< / button>
< / form>
< / div>
< / td>
< td>
< div class =col-sm-9>
< form action =＃th：action =@ {/ genpdf}
th：object =$ {booking}method =post
role =form >
< button type =submitclass =btn btn-primary btn-block>生成PDF< / button>
< / form>
< / div>
< / td>
< / tr>
< / tbody>
< / table>
< / div>
< / body>
< / html>
编辑：有人请帮助告诉我一个简单的方法来传递对象，因为我必须使用它许多地方和对象在某些情况下也包含许多子对象。例如。以下情况：
< div style =margin-top：2cmclass =container>
< table class =table table-bordered table-striped>
< thead>
< tr>
< td>来源< / td>
< td>目的地< / td>
< td>金额< / td>
< td>货币< / td>
< td>动作< / td>
< / tr>
< / thead>
< tbody>
< tr th：if =$ {offering.empty}>
< td colspan =5>无优惠< / td>
< / tr>
< 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 = 形式 >
< button type =submitclass =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改变模板，并尝试逐个赋值，但我仍然在控制器中将其作为空值。
< table class =table table-bordered table-striped>
< thead>
< tr>
< td>来源< / td>
< td>目的地< / td>
< td>金额< / td>
< td>货币< / td>
< td>动作< / td>
< / tr>
< / thead>
< tbody>
< tr th：if =$ {offering.empty}>
< td colspan =5>无优惠< / td>
< / tr>
< 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 = 形式 >
< input type =hiddenth：attr =value = $ {offer.route.from}th：field =* {routeStart}/>
< input type =hiddenth：attr =value = $ {offer.route.to}th：field =* {routeDestination}/>
< input type =hiddenth：attr =value = $ {offer.price.amount}th：field =* {bookingCharges}/>
< input type =hiddenth：attr =value = $ {offer.price.currency}th：field =* {chargesCurrency}/>
< button type =submitclass =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 =新的ModelAndView（）;
AirlineOffer [] offersArray = airlineClient.getOffers（）;
列表< AirlineOffer> offers = Arrays.asList（offersArray）;
modelAndView.addObject（offers，offers）;
预订预订=新预订（）;
modelAndView.addObject（booking，booking）;
modelAndView.setViewName（user / booking）;
返回modelAndView;
$ b $ **提交存款请求的POST方法* /
@RequestMapping（value =/ user / booking，method = RequestMethod.POST）
public ModelAndView book（@Valid Booking booking，
BindingResult bindingResult，HttpServletRequest request）
{
ModelAndView modelAndView = new ModelAndView（）;
......
}
解决方案
< table class =table table-边界条纹>
< thead>
< tr>
< td>来源< / td>
< td>目的地< / td>
< td>金额< / td>
< td>货币< / td>
< td>动作< / td>
< / tr>
< / thead>
< tbody>
< tr th：if =$ {offering.empty}>
< td colspan =5>无优惠< / 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 = 形式 >
< input type =hiddenth：value =$ {offer.route.from}name =routeStart/>
< input type =hiddenth：value =$ {offer.route.to}name =routeDestination/>
< input type =hiddenth：value =$ {offer.price.amount}name =bookingCharges/>
< input type =hiddenth：value =$ {offer.price.currency}name =chargesCurrency/>
< button type =submitclass =btn btn-primary btn-block> Book< / button>
< / form>
< / td>
< / tr>
< / tbody>
只需删除 th：field 并添加 name 属性。
Let's say I have rendered the output rom the get request on an html template, now I need to use this same data to pass to a post request via a button on a same page. How do I do that?
I'm trying to do something like this:
<!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>
Edit: Somebody please help tell me a simple method to pass the object since I have to use it at many places and object contains many child object as well in some cases. eg. the following case:
<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>
UPDATE 2:
I even changed the template by sending a new object in the get request and try to assign values one by one but I still get it as null in a controller.
<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 = ${offer.price.currency}" th:field="*{chargesCurrency}" />
<button type="submit" class="btn btn-primary btn-block">Book</button>
</form>
</td>
</tr>
</tbody>
</table>
These are my get and post methods:
@RequestMapping(value="/user/booking", method = RequestMethod.GET)
public ModelAndView getOffers()
{
ModelAndView modelAndView = new ModelAndView();
AirlineOffer[] offersArray= airlineClient.getOffers();
List<AirlineOffer> offers = Arrays.asList(offersArray);
modelAndView.addObject("offers", offers);
Booking booking = new Booking();
modelAndView.addObject("booking", booking);
modelAndView.setViewName("user/booking");
return modelAndView;
}
/** POST method for submitting deposit request */
@RequestMapping(value = "/user/booking", method = RequestMethod.POST)
public ModelAndView book(@Valid Booking booking,
BindingResult bindingResult, HttpServletRequest request)
{
ModelAndView modelAndView = new ModelAndView();
......
}
解决方案
Alright, I finally resolved it using the following in my form:
<table class="table table-bordered table-striped">
<thead>
<tr>
<td>Source</td>
<td>Destination</td>
<td>Amount</td>
<td>Currency</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr th:if="${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>
All it took was to remove th:field and add the name attribute.
