Postman: Required request part 'file' is not present

I wanted to upload an image to my Rest API through postman. I am using spring boot framework. Here is the screen shot:

I also have not set any any headers as I found in other stack overflow answers that it gives multipart boundary error.

Now, below is my controller code:

package com.practice.rest.assignment1.controller;import java.io.IOException;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.multipart.MultipartFile;import com.practice.rest.assignment1.model.Product;import com.practice.rest.assignment1.service.CatalogueService;import org.codehaus.jackson.JsonParseException;import org.codehaus.jackson.map.JsonMappingException;import org.codehaus.jackson.map.ObjectMapper;@RestController@RequestMapping("/CatalogueController/")public class CatalogueController{    @Autowired    private CatalogueService catalogueService;    @RequestMapping(value = "addProduct", method = RequestMethod.POST , consumes = "multipart/form-data")    public Product addProduct(@RequestParam String productJson, @RequestParam MultipartFile file) throws JsonParseException, JsonMappingException, IOException {        Product product = new ObjectMapper().readValue(productJson, Product.class);        byte[] mediaBytes = file.getBytes();        product.setImage(mediaBytes);        return catalogueService.saveInDb(product);    }}

Now, I am taking a Product object which consists internally an image defined as byte[] array. I take this as string and image separately as Multipart file.

Below is my product class attributes defined :

    private Long pId;    private String model;    private String brand;    private byte[] image; // This is where I want the image to save    private Long price;    private String currency;    private String transmissionType;    private String fuelType;

Since , I am using spring boot , here is my Main class :

package com.practice.rest.assignment1;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class App {  public static void main(String[] args) {      SpringApplication.run(App.class, args);    }}

The error on postman I get is :

{"timestamp": 1478611635977,"status": 400,"error": "Bad Request","exception": "org.springframework.web.multipart.support.MissingServletRequestPartException","message": "Required request part 'file' is not present","path": "/CatalogueController/addProduct"}

Where am I wrong ?
