Question

我正在尝试绑定与AJAX调用中的其他数据一起序列化的表单数据。我似乎无法让Spring接受它。它只是实例化一个空表格。

JavaScript的：

$.ajax({
method: "GET",
url: contextPath,
data: {"form": serializedForm, "otherStuff": otherStuff},
contentType:"application/json; charset=utf-8",
cache: false,
success: function(data) {});

控制器：

@ResponseBody
@RequestMapping(value="/blah", method=RequestMethod.GET)
public String blah(@ModelAttribute("form") Form form, @RequestParam(value="otherStuff[]", required=false) String[] otherStuff, HttpServletResponse response){
    //stuff
}

有没有办法让Spring在方法参数中映射我的表单？

似乎我可以从HttpServletRequest中单独获取参数，但我最好喜欢我的表单来通过InitBinder。

问题似乎与AJAX请求有关。对每个方法参数使用键值配对不适用于数据绑定。相反，如果我将序列化数据连接成单个字符串，Spring将能够将它映射到每个对象。

public GoogleCloudDialogflowV2WebhookResponse Search(GoogleCloudDialogflowV2WebhookRequest request)
    {
        GoogleCloudDialogflowV2WebhookResponse whr = new GoogleCloudDialogflowV2WebhookResponse();

        whr.FulfillmentMessages = new List<GoogleCloudDialogflowV2IntentMessage>();

        whr.FulfillmentMessages.Add(new GoogleCloudDialogflowV2IntentMessage()
        {                
            Platform = "ACTIONS_ON_GOOGLE",
            SimpleResponses = new GoogleCloudDialogflowV2IntentMessageSimpleResponses()
            {
               SimpleResponses = new List<GoogleCloudDialogflowV2IntentMessageSimpleResponse>()
               {
                   new GoogleCloudDialogflowV2IntentMessageSimpleResponse()
                   {
                       DisplayText = "sample text",
                       Ssml = "<speak>sample text</speak>"
                   }
               }
            },
            BasicCard = new GoogleCloudDialogflowV2IntentMessageBasicCard()
            {             
                Title = "sample title",
                Subtitle = "sample subtitle",
                FormattedText = "sample formatted text",
                Image = new GoogleCloudDialogflowV2IntentMessageImage()
                {                 
                    ImageUri = "https://assistant.google.com/static/images/molecule/Molecule-Formation-stop.png",
                    AccessibilityText = "sample image"
                }
            }
        });

        return whr;
    }

我不确定是否有更简洁的方法可以避免将对象聚集成一个字符串，但这是有效的。
