    public ResponseEntity getUser(@PathVariable("uuid") String uuid) {
        UserJson userJson = new UserJson(uuid, "bob");
        return new ResponseEntity<>(userJson, HttpStatus.OK);

public class UserJson {

    @JsonProperty(value = "uuid")
    private String uuid;

    @JsonProperty(value = "name")
    private String name;

    public UserJson(String uuid, String name) {
        this.uuid = uuid; = name;
