Controller

A controller is a class that handles requests and responds with information of some sort. In case of a browser-facing application, a controller responds by optionally populating model data and passing the request to a view that produces HTML to be returned to the browser. The view is indicated by its logical name, which is returned by the method.

@Controller @GetMapping

@Controller
public class HomeController {

    @GetMapping("/")
    public String home() {

        // returns the view name
        return "home";
    }
}

POSTing Resource. Data

This overloaded version allows you to receive the newly created resource as a domain model object:

RestTemplate restTemplate = new RestTemplate();

MyResource model = new MyResource(...);

MyResource created = restTemplate.postForObject("http://localhost:8080/myresource", model, MyResource.class);
