Spring MVC Controllers, JAVA Programming

Assignment Help:
I want to upload an item object with it''s image is it possible that i pass a complete object of my Item along with it''s image from my Controller if yes then how may i Do it? and I need a Json Pattern also which will be coming from client side.

What would be the Json pattern for my following Item Object.

Class Item{

String ItemID;
String ItemName;
String CategoryID;
List imagesList;

}

Class Image{

String imageId;
String imageTitle;
byte[] image;
}



and one more thing. Please tell me how can I pass two parameters in my Controller. e.g. if I want to pass Item object in the Request Body along with an extra parameter say String UserID. HOw may I write the following code.

@RequestMapping(method = RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
public void add(@RequestBody Item myItem, String UserID)

{ ...... }

and please tell me what if I pass in the Request in Json format. What will be it looks like?

{ "Item" : { "ItemID": "1", ......}, "UserID" : "hello"}

will it be like this or what? because i tried it i''m getting the Object and string as Null. I also tried it with @RequestParam but same got NULL while debugging.

Currently i''m dealing with this by this.

Class ItemUserPost{
Item item;
String UserID;
}



I''m storing this object in MongoDB. Will be my whole collection of Item will stored along with the images? or i have to use a MultiPart and GridFS API for this. Kindly please refer if related question already posted.

Please Help Urgent.

Thanks in Advance.
