我想在angularjs中发送servlet

Question

我想使用angularjs发送ImageFile（MultipartFile）servlet。 但是，它无法进入@RequestParam Annotation spring。

JSP

<form method="POST" id="image-form" enctype="multipart/form-data">
    <input type="file" id="imageFile" name="imageFile" accept="image/jpg,image/jpeg,image/png" />
    <div id="search-button">
        <input type="button" ng-click="searchCtrl.imageSearch();">
    </div>
</form>

的javascript

var $form;
var formData = new FormData();

$form = $("#image-form");
formData.append("imageFile", $form[0]);

request = $http({
    method : 'post',
    url : "/addImage",
    data : data,
    headers : {
        'Content-Type' : undefined
    },
    transformRequest : null
});

return (request.then(handleSuccess, handleError));

的java

@RequestMapping(value = "/addImage", method = RequestMethod.POST)
@ResponseBody
public List<SearchImageRequestModel> logo_upload(HttpServletRequest request, HttpServletResponse response,
    Model model, @PathVariable("service_id") String serviceId, @RequestParam(value = "imageFile") MultipartFile file)
    throws ServletException, IOException {
...

您是否无法在@RequestParam注释中获取MultipartFile。 请劝告。
