orderList.html에서 검색시 전체회원만 조회가 됩니다.

orderList.htm에서 회원이름 및 주문상태를 선택한 후 검색을 누르면 OrderController orderList 메소드가 호출 되는데

orderSearch 객체의 멤버변수 모두 null로 입력이 되어 있어서 전체 회원 조회밖에 안되내요.

@GetMapping(value = "/orders")
    public String orderList(@ModelAttribute("orderSearch") OrderSearch orderSearch, Model model) {
        List<Order> orders = orderService.findOrders(orderSearch);
        model.addAttribute("orders", orders);
        return "order/orderList";
    }
