Spring rest controller giving unsupported content type

Hello all here is what i have:

StockController.java

@RestController
public class StockController {

    @Autowired
    private StockRepository repository;

    @RequestMapping(value = "stockmanagement/stock")
    public ResponseEntity<?> addStock(@RequestBody String stock
    ) {

        System.out.println(stock);

        return new ResponseEntity<>(HttpStatus.OK);
    }

when I make a request like so using chrome advanced rest extension :

Raw Headers

Content-Type: application/json

Raw Payload

{"stock": {"productId": 2, "expiryAndQuantity" : {}, "id": 0}}

It works fine in that out comes a string of json

However when i try to replace String stock with Stock stock where stock looks like this:

public class Stock {

    @Id
    private String id;

    private String productId;

    private Map<LocalDateTime, Integer> expiryAndQuantity;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getProductId() {
        return productId;
    }

    public void setProductId(String productId) {
        this.productId = productId;
    }

    public Map<LocalDateTime, Integer> getExpiryAndQuantity() {
        return expiryAndQuantity;
    }

    public void setExpiryAndQuantity(Map<LocalDateTime, Integer> expiryAndQuantity) {
        this.expiryAndQuantity = expiryAndQuantity;
    }

    @Override
    public String toString() {
        return String.format(
                ""
        );

    }
}

I get an error where by the following is fed back to me:

"status": 415
"error": "Unsupported Media Type"
"exception": "org.springframework.web.HttpMediaTypeNotSupportedException"
"message": "Content type 'application/json;charset=UTF-8' not supported"
"path": "/stockmanagement/stock"

My question is; how do i create a request which maps to my Stock object.

instead of accepting a String Accept a Stock object.and accept it from a post request than having a get request

@RequestMapping(value = "stockmanagement/stock",method=RequestMethod.POST)
public ResponseEntity<?> addStock(@RequestBody Stock stock){
}

and your request should be sent like this

{
   "productId": 2
  ,"expiryAndQuantity" : null
  ,"id": 0
}

all parameter names should be equal to the objects filed names,since spring has jackson binders on class path and object will be created inside the controller method. if you are planning on passing different parameters from the post request you can use 

@JsonProperty("pid")
private String productId;

on the field name.

You can try with @JsonRootName annotation, by default Spring serialize using no root name value. like this:

{"productId": 2, "expiryAndQuantity" : {}, "id": 0}

But if you want that your serialization has a rootname you need to use @JsonRootName annotation.

@JsonRootName(value = "Stock")

And it'll produce something like this

{"Stock": {"productId": 2, "expiryAndQuantity" : {}, "id": 0}}
