服务层：

 1、接口

package org.jeecg.modules.bidding.service;

import org.jeecg.modules.bidding.entity.BidNotice;
import com.baomidou.mybatisplus.extension.service.IService;

/**
 * @Description: 公告管理
 * @Author: jeecg-boot
 * @Date:   2022-05-06
 * @Version: V1.0
 */
public interface IBidNoticeService extends IService {
    void updateSortByDel(BidNotice bidNotice);
    int increVisit(String id);
}

2、实现

package org.jeecg.modules.bidding.service.impl;

import org.jeecg.modules.bidding.entity.BidNotice;
import org.jeecg.modules.bidding.mapper.BidNoticeMapper;
import org.jeecg.modules.bidding.service.IBidNoticeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;

/**
 * @Description: 公告管理
 * @Author: jeecg-boot
 * @Date:   2022-05-06
 * @Version: V1.0
 */
@Service
public class BidNoticeServiceImpl extends ServiceImpl implements IBidNoticeService {
    @Autowired
    private BidNoticeMapper bidNoticeMapper;
    @Override
    public void updateSortByDel(BidNotice bidNotice) {

        bidNoticeMapper.updateById(bidNotice);
        return bidNotice.getVisit();
    }
}

dao层：

1、mapper

package org.jeecg.modules.bidding.mapper;

import java.util.List;

import org.apache.ibatis.annotations.Param;
import org.jeecg.modules.bidding.entity.BidNotice;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;

 */
public interface BidNoticeMapper extends BaseMapper {
    void updateSortByDel(BidNotice bidNotice);
}

2、mybatis文件

    
        update bid_notice
        
            sort = sort - 1
        
        where sort > #{sort}
        and is_top = #{isTop}
