@RestController

  private final OrderModelAssembler assembler;

  OrderController(OrderRepository orderRepository, OrderModelAssembler assembler) {

    this.orderRepository = orderRepository;
    this.assembler = assembler;
  }

  @GetMapping("/orders")

    List<EntityModel<Order>> orders = orderRepository.findAll().stream() //
        .map(assembler::toModel) //
        .collect(Collectors.toList());

    return CollectionModel.of(orders, //
        linkTo(methodOn(OrderController.class).all()).withSelfRel());
  }

  @GetMapping("/orders/{id}")

  @PostMapping("/orders")
