Java Spring绑定问题

当点击下面显示的控制器方法时，我总是得到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());
}

我为什么能拿到500英镑。我彻底检查并确认jsp绑定中存在问题。任何帮助都将不胜感激

谢谢

尝试将

path=“TrinvoiceList[

替换为

path=“transferinvoiceType[

我相信你应该做得很好。这里的问题是你可以访问arraylist元素，你正在使用c:foreach中的var属性值集对其进行迭代，当你查看你的代码时，你会发现你正在试图直接访问object的属性。

你可以使用以下过程从这种情况中恢复。 无论何时使用JSTL表单标记，您都可以在jsp页面中使用：

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

使用

method=RequestMethod.POST

请添加更多信息（为什么是对的和其他错误等）。回答质量较低的会很快被删除。从社区中！仍然得到相同的500个错误。我在这里遵循此解决方案仍然面临此问题，有人能重新审视吗？
