伙计们,你能帮助我,我坚持这个问题,我有一个表格,我选择不同的服务,应该添加到订单。问题是我无法获得所选复选框的这些值,甚至在控制台中也没有任何错误。看起来我的servlet现在从未运行,我尝试了不同的方法来解决这个问题,但没有任何帮助。多个复选框与JSP和Spring MVC,如何获取值
这里是在jsp页面:
<!-- SERVICE TABLE -->
<form class="form-horizontal" action="/clients/addOrder/${client.id}" method="POST" >
<table class="table table-striped table-bordered table-condensed" >
<tr>
<th><spring:message code="label.serviceId" /></th>
<th><spring:message code="label.serviceName" /></th>
<th><spring:message code="label.servicePrice" /></th>
<th><spring:message code="label.actions" /></th>
</tr>
<c:forEach var="service" items="${servicesList}">
<tr id="${service.service_id}">
<td><c:out value="${service.service_id}" /></td>
<td><c:out value="${service.service_name}" /></td>
<td><c:out value="${service.service_price}" /></td>
<td><input type="checkbox" name="serviceBox"
value="${service.service_id}" /></td>
</tr>
</c:forEach>
</table>
<div class="form-group form-group-sm">
<div class="col-sm-offset-2 col-sm-10">
<a class="pull-right">
<button class="btn btn-primary" type="submit"><c:out value="Add order"/></button>
</a>
</div>
</div>
<input type="hidden" name="clientId" value="${client.id}">
</form>
的servlet
@RequestMapping(value = "/addOrder/{clientId}", method = RequestMethod.POST)
public String addOrder(@Valid @PathVariable("clientId") Long clientId, @ModelAttribute("serviceBox") String[] services, BindingResult result,
Model model) {
System.out.println("IN addOrder POST");
if (result.hasErrors()) {
AllServicesEvent ase = servicesService
.requestAllServices(new RequestAllServicesEvent());
model.addAttribute("servicesList", ase.getServices());
return "addOrderForm";
}
System.out.println("NO MISTAKES");
List<Services> servicesList = servicesService.requestService(new RequestServiceEvent(services)).getServicesList();
System.out.println("Service List size: " + servicesList.size());
if (servicesList != null && servicesList.size() > 0) {
// update orders amount and total price
System.out.println("IN IF METHOD");
ClientUpdatedEvent cue = clientsService.updateClient(new UpdateClientEvent(clientId, servicesList));
System.out.println("AFTER UPDATING CLIENTS");
// add order to orders table, add order id, service id to order_service table
OrderCreatedEvent oce = ordersService.addOrder(new CreateOrderEvent(clientId, servicesList));
System.out.println("AFTER ADDING ORDERS");
return "redirect:/clients";
} else {
return "addOrderForm";
}
}
在控制台:

Hibernate: select services0_.service_id as service_1_4_, services0_.service_name as service_2_4_, services0_.service_price as service_3_4_ from services services0_
而不是结果我只有与网页:
HTTP Status 404 - /clients/addOrder/1
--------------------------------------------------------------------------------
type Status report
message /clients/addOrder/1
description The requested resource is not available.
UPD:这样它的工作原理:
@RequestMapping(value = "/addOrder/{clientId}", method = RequestMethod.POST)
public String addOrder(@PathVariable("clientId") Long clientId) {
System.out.println("IN addOrder POST, id" + clientId);
return "addOrderForm";
}
所以,唯一的问题是如何在正确的方式获得的servlet checkboxed值。
您requestmapping是'/ addOrder/{}的clientId'和你从提交到'/客户/ addOrder/$ {client.id}'。这对我来说并不合适。 – 2014-10-01 20:19:37
我开始检查空的servlet。它的工作原理与这些参数:\t @RequestMapping(值= “/ addOrder/{的clientId}”,方法= RequestMethod.POST) \t公共字符串addOrder(@PathVariable( “的clientId”)长的clientId){ \t \t的System.out .println(“IN addOrder POST,id”+ clientId); \t \t return“addOrderForm”; \t} – Cooler 2014-10-01 20:43:56
