在Spring 3中如何上传图像并将JSON发布到RESTful Web服务

Question

I am trying to post a JSON entity and an image to my web service. However I don't manage to get it working. Last error is that the request is not a multipart request.

@RequestMapping(method = RequestMethod.POST)
public ResponseEntity savePerson(@RequestPart("data") final PersonResource personResource, @RequestPart("image") MultipartFile imageFile) { ... }

CURL

$ curl -H "Content-Type: application/json" -X POST -F 'data={"name":"Tes
t"}' -F "image=@C:\Users\LuckyLuke\Downloads\test.jpg;type=image/jpg" localhost:8080/myapp/persons

Have I misunderstood the usage of @RequestPart annotation? Is the request wrong?

Answer 1

As far as I can see you are using @RequestMapping in a proper way. My guess is that you are geting error since you are enforcing application/json content type (-H "Content-Type: application/json"). Try to run your program without that header (-F option should take care of setting multipart/form-data request).
