【问题描述】：

MultipartBody.Part.createFormData(contentType, file.getName(), progressRequestBody);// mulitpart

//parameter
String json = gson.toJson(story);
RequestBody requestBody = RequestBody.create(MultipartBody.FORM, json);
parts.add(mulitpart);

//execute ...
Call<Integer> callGetStoryIdByUploadingStoryApi = storyRepository.saveStory(requestBody, parts);

@Multipart
@POST("./")
Call<Integer> saveStory(
        @Part("story") RequestBody story,
        @Part List<MultipartBody.Part> files);

我尝试将 Retrofit List 和 Object 发送到 spring MVC 得到下面的输出

<!DOCTYPE html><html><head><title>Apache Tomcat/8.0.32 (Ubuntu) - Error 
    report</title><style type="text/css">H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-

    <h3>Apache Tomcat/8.0.32 (Ubuntu)</h3></body></html>

这是我在春天的代码

@RequestMapping(value = "/", method = RequestMethod.POST)
@ResponseBody
public long insertStory(@RequestBody Story story, @RequestPart  List<MultipartFile> files )
        throws Exception {
    return storyService.insertStory(story, files);
}

我该怎么办？ OTL 我想得到一些提示..请^^

【解决方案1】：

你的 Spring 代码是错误的。

@RequestMapping(value = "/", method = RequestMethod.POST)
@ResponseBody
public long insertStory(@RequestPart("Story") Story story, @RequestPart  List<MultipartFile> files )
        throws Exception {
    return storyService.insertStory(story, files);
}

这样改。
