我正在尝试将 Spring 表单与我的控制器一起使用,并且它映射到的实体具有嵌套对象。当尝试使用表单点击页面时,它会引发以下错误。
我没有正确初始化模型吗?
控制器:
@RequestMapping(value = "/payPal2",
headers = "Accept=application/json",
method = RequestMethod.POST)
public
@ResponseBody
Payment payByCreditCard2(@ModelAttribute("orderContext") OrderContext orderContext, Model model) throws Exception {
PaymentWithCreditCard paymentWithCreditCard = new PaymentWithCreditCardImpl();
model.addAttribute("billingAddress", new Address());
OTHER Setters and getters down here
表格:
<form:form modelAttribute="orderContext" method="post" action="/service/payments/payPal2">
<form:input path="billingAddress.city"/>
</form:form>
错误:
org.apache.jasper.JasperException: An exception occurred processing JSP page /paypalTest.jsp at line 14
11: </head>
12: <body>
13: <form:form modelAttribute="orderContext" method="post" action="/service/payments/payPal2">
14: <form:input path="billingAddress.city"/>
15: </form:form>
16: </body>
17: </html>
