我需要创建一个接受RequestBody或RequestPart的端点。
如果请求包含RequestPart,它将执行一些逻辑来处理MultipartFile,否则它将处理RequestBody中传递的对象。
我检查了How to send @Requestbody and @Requestpart together in spring,但与我的问题有所不同,因为我不想同时发送RequestBody和RequestPart。
我将入口点定义为:
@RequestMapping(value="/xyz/api/{endPoint}", method= RequestMethod.POST)
public void endPointPost(
@PathVariable String endPoint,
HttpServletRequest request,
HttpServletResponse response,
@RequestBody(required=false) Object body,
@RequestPart(required=false) MultipartFile uploadFile) throws Exception {
如果请求仅包含RequestBody,则它可以正常工作,例如:
{"body":{"companyCD":"myTest"}}
但是,当发送多部分请求时,它失败并出现以下错误:

请注意,Could not resolve parameter [3]...
引用RequestBody参数。
这是我的多方要求:

感谢您的任何帮助。
谢谢
我从RESTful的角度考虑这个问题,并不一定是春天。如果您是1)尝试创建或编辑(发布或放置)资源,或2)尝试上传文件;那不应该是两个不同的URI路径吗?
