Hello,

I'm using Spring MVC 3.0.3 on backend and Ext JS on frontend.

When creating a new record in grid, Ext send a POST request with following JSON string:

{"data":{"name":"aa","label":"a","description":"a" }}

The record is wrapped in a JSON object named "data".

From what I have seen and read, Spring Jackson message converter expects the objet directly as below:

Code:
{"name":"aa","label":"a","description":"a"}
I implemented a wrapper class ExtJsRequest in order to mimic the JSON wrapping.

Code:
public class ExtJsRequest {

	private Application data;

	public void setData(Application data) {
		this.data = data;
	}

	public Application getData() {
		return data;
	}
}
And I used @RequestBody as below:

Code:
@RequestMapping(value = "/application", method = POST)
public ModelAndView create(@RequestBody ExtJsRequest extRequest, HttpServletResponse response) {
	...
}
An alternative would be to customize the Ext.data.JsonWriter to suppress object wrapping on client side.

But I was wondering if there is a more convenient way to do it in Spring: in the controller or message converter?

Thanks,

Phil
