根据自己的类添加以下加粗/红色标注的代码即可实现

package com.bootdo.publicOrder.utils;
    
    import javax.annotation.PostConstruct;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Configuration;
    
    import com.bootdo.publicOrder.domain.OrderInfoCom;
    import com.bootdo.publicOrder.domain.OrderReturnInfoCom;
    import com.bootdo.publicOrder.service.OrderInfoService;
    
    @Configuration
    public class PublicMiddleUtil {
        @Autowired
        private OrderInfoService orderService;
        public static PublicMiddleUtil middleUtil;
        @PostConstruct
        public void init() {
            middleUtil = this;
            middleUtil.orderService = this.orderService;
        }
        public static OrderReturnInfoCom middleEntrance(OrderInfoCom f) {
             return new PublicMiddleUtil().orderEntrance(f);
        }
        public OrderReturnInfoCom orderEntrance(OrderInfoCom f) {
           OrderReturnInfoCom result = new OrderReturnInfoCom();
           if (null!=f) {
               
                }if("queryProductsList".equals(f.getMethod())) {
                    result = middleUtil.orderService.queryOrderProducts(f);
                }
            }
           return result;
       }
    }

根据自己的类添加红框代码
