Is it common to use Spring @RestController to process Ajax request?

[Ekaterina Galkina]

When you update a web page partially and send a request which format is usually used to communicate with server? JSON? Is it usually a RESTfull call?

[Stephan van Hulst]

That would be my preferred way, yes. You can just send a JavaScript object as the request body, and use the response (also in JSON) to update the model at the client side, which will automatically update the UI if you're using a JavaScript framework that supports model-view bindings.
