OrderServiceImpl implements OrderService { @Override public List<OrdersEntity> findOrdersForSeller(OrderQueryReq orderQueryReq, String sellerId) { checkParam(orderQueryReq, ExpCodeEnum.ORDERQUERYREQ_NULL); orderQueryReq.setSellerId(sellerId); return orderDAO.findOrders(orderQueryReq); }  @Override List<OrdersEntity> findOrdersForBuyer(OrderQueryReq orderQueryReq, String buyerId); @Override List<OrdersEntity> findOrdersForSeller(OrderQueryReq orderQueryReq, String sellerId); @Override List<OrdersEntity> findOrdersForAdmin(OrderQueryReq orderQueryReq); @Override String placeOrder(OrderInsertReq orderInsertReq, String buyerId); @Override String pay(String orderId, String userId); @Override void cancelOrder(String orderId, String userId); @Override void confirmDelivery(String orderId, String expressNo, String userId); @Override void confirmReceive(String orderId, String userId);  }### Answer:
@Test public void findOrdersForSeller() throws Exception { OrderQueryReq orderQueryReq = new OrderQueryReq(); List<OrdersEntity> ordersEntityList = orderService.findOrdersForSeller(orderQueryReq, SELLER_ID); System.out.println(ordersEntityList); }
