Java Spring MVC - Send JSON request body error

I am trying to send a JSON string as a request to my application. This is my code: 

@RequestMapping(
        value = "/mylink/upload",
        method = RequestMethod.POST,
        consumes ="application/json",
        produces = "application/json")
public
@ResponseBody
List<Upload> upload(
        @RequestParam(value = "hdfsLocation") String hdfsLocation

) throws Exception {
    return S3HdfsTransfer.uploadFromHDFS(hdfsLocation);
}

I am trying to send a request with Postman. The method I use is POST, the header contains: Accept "application/json",Content-Type "application/json", the request body is the following:

{
    "hdfsLocation" : "hdfs://145.160.10.10:8020"
}

This is the response I get. If I put the parameter in the URL, it works.

{
  "httpStatus": 500,
  "appErrorId": 0,
  "message": "Required String parameter 'hdfsLocation' is not present",
  "trackingId": "8c6d45fd-2da5-47ea-a213-3d4ea5764681"
}

Any idea what I am doing wrong?

Thanks, Serban

Shouldn't it be @RequestBody instead of @RequestParam? Also, even after using @RequestBody, the whole of the JSON string: { "hdfsLocation" : "hdfs://145.160.10.10:8020" } will be the value of String hdfsLocation and not just the hdfs url. Hence, you'll have to JSON parse that JSON by yourself to get just the hdfs url.

Looks like you have confused @RequestBody with @RequestParam. Do either of following :

I guess you over looked :)
