mybaits 分页查询级返回结果集实现

代码实现

public QueryResponseResult myBookCourt(Integer id,int pageNum, int pageSize) {
        
        //分页参数
        if(pageNum <= 0){
            pageNum = 1;
        }
        if(pageSize <= 0){
            pageSize = 10;
        }
        // 分页插件查询 jdk8 lambda用法
        PageInfo<BookCourt> pageInfo = PageHelper.startPage(pageNum, pageSize).doSelectPageInfo(
                () ->
                        bookCourtMapper.selectBookCourtListByUserId(id.longValue())
        );

        // 封装查询结果
        QueryResponseResult result = new QueryResponseResult(
                CommonCode.SUCCESS,
                new QueryResult()
                        .setTotal(pageInfo.getTotal())
                        .setList(pageInfo.getList()));
        return result;
    }
