#### Orders实体类 ####

@Data
    public class Orders {
        
        private String id;
        private String orderNum;
        @DateTimeFormat(pattern="yyyy-MM-dd HH:mm")

        private Member member;
        private Integer payType;
        private String payTypeStr;
        private String orderDesc;
        //用于添加订单时，添加产品，会员
        private Integer productId;
        private Integer memberId;
    
        public String getOrderTimeStr() {
        
            // 对日期格式化
            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
            if (null != orderTime) {
        
                orderTimeStr = dateFormat.format(orderTime);
            }
            return orderTimeStr;
        }
    
        public String getPayTypeStr() {

                payTypeStr = "支付宝";
            } else if(payType == 1){
        
                payTypeStr = "微信";
            }else if(payType == 2){

                orderStatusStr = "未支付";
            } else if(orderStatus == 1){
        
                orderStatusStr = "已支付";
            }
            return orderStatusStr;
        }
    }

#### 编写OrdersMapper ####

public interface OrderMapper {

         * 分页查询所有订单
         */
        List<Orders> findAll();

#### 编写OrdersService ####

public interface OrderService {

         * 分页查询所有订单
         * @param page
         * @param size
         * @return
         */
        List<Orders> findAll(Integer page, Integer size);
    }

@Service
    public class OrderServiceImpl implements OrderService {
        
        
        @Autowired

        /**
         * 查询订单
         * @return
         */
        @Override

            return this.orderMapper.findAll();
        }
    }

#### 编写OrdersController ####

@Controller

            PageHelper.startPage(page,size);
            List<Orders> orders = this.orderService.findAll();
    
            PageInfo pageInfo = new PageInfo(orders);
    
            model.addAttribute("pageInfo",pageInfo);
            return "order-list";
        }
    }

#### 编写OrdersMapper.xml ####

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="cn.yanqi.ssm.mapper.OrderMapper">
