Question

我在下面显示的控制器方法时总是得到500.

@RequestMapping(value ="transferInvoiceHdrForm", method = RequestMethod.GET)
protected ModelAndView showForm(@ModelAttribute("transferInvoice") TransferInvoiceForm trinvoiceform, final HttpServletRequest request, final HttpServletResponse response, Model model)throws Exception {
        TransferInvoiceHdr transferInvoiceHdr = new TransferInvoiceHdr();
        List<TransferInvoice> transferinvoice= transferInvoiceHdrService.getAssetCategoriesandTransfer();
        List<Employees> employees = transferInvoiceHdrService.getAssignEmployee();
        trinvoiceform.setTrinvoiceList(transferinvoice);
        log.info("++++"+trinvoiceform.getTrinvoiceList());
        model.addAttribute("employees", employees.get(0).getFullname());
    //  model.addAttribute("transferinvoice", transferinvoice);
        model.addAttribute("transferInvoiceHdr", transferInvoiceHdr);
        //model.addAttribute("transferInvoice", transferinvoice);

    return new ModelAndView("asset/transferInvoiceHdrForm", model.asMap());
}

我的Pojo与objets列表看起来像

public class TransferInvoiceForm {
private List<TransferInvoice> TrinvoiceList;
//getters and setters

在我的JSP中我使用路径变量，如下所示

<form:form method="post" action="/asset/invoice/searchctr" modelAttribute="transferInvoice">
             <fieldset>
              <c:forEach var="transferinvoiceType" items="${transferInvoice.TrinvoiceList}" varStatus="status">
                     <form:select path="TrinvoiceList[${status.index}].assetName" class="col-xs-12 col-lg-5 form-group">
                            <form:option value="0" selected="true">All</form:option>
                            <form:options value="${transferinvoiceType.assetName}"></form:options>
                    </form:select>
                    </c:forEach>
                     <c:forEach var="transferinvoiceType" items="${transferInvoice.TrinvoiceList}" varStatus="status">
                    <form:select path="TrinvoiceList[${status.index}].assettoLocation" class="col-xs-12 col-lg-5 form-group">
                             <form:option value="0" selected="true">All</form:option>
                            <form:options value="${transferinvoiceType.assettoLocation}"></form:options>
                        </form:select>
                     </c:forEach>

                    <button class="btn btn-primary" type="submit" class="col-xs-12 col-lg-6 form-group">
                        <fmt:message key="button.search" />
                    </button>
            </fieldset> 
        </form:form>

另一个有用的java bean

 public class TransferInvoice {
    private String assetName;
    private String assettoLocation;
    private String actualTransferDate;
    private String scanserialCode;
    private String modelNum;
    private boolean check;
    //getters and setters

任何帮助我为什么得到500.我彻底检查并确认问题在我的jsp绑定中退出。任何帮助，将不胜感激。

Answer 1

您可以使用以下过程从此情况中恢复。无论何时使用JSTL表单标记，都可以在jsp页面中使用：

<form:form commandName="viewModel" method="POST">

在控制器部分，您可以直接使用TransferInvoice模型从jsp页面获取所有数据。如果有必要将数据保存在TransferInvoiceForm pojo中，那么您可以在控制器下管理它。所以你可以按照以下代码：

@RequestMapping(value ="yourValue", method = RequestMethod.POST)
protected ModelAndView showForm(@ModelAttribute("viewModel") TransferInvoice transferInvoice, final HttpServletRequest request, final HttpServletResponse response, Model model)throws Exception {
   //use every thing for transferInvoice
}

使用method = RequestMethod.POST

Answer 2

尝试用path="TrinvoiceList[替换path="transferinvoiceType[，我相信你应该做得很好。这里的问题是你可以使用c：foreach中var属性的值集来访问你正在迭代的arraylist元素，当你查看代码时，你会看到你试图直接访问对象的属性。
