mybatis-plus查找单个字段的办法 

                LambdaQueryWrapper<SrmSrpProdGroupReply> replyLambdaQueryWrapper = new LambdaQueryWrapper<>();
                replyLambdaQueryWrapper.select(SrmSrpProdGroupReply::getId).eq(SrmSrpProdGroupReply::getProdGroupId, srmSrpProdGroup.getId());

                List<SrmSrpProdGroupReply> srmSrpProdGroupReplies = srmSrpProdGroupReplyMapper.selectList(replyLambdaQueryWrapper);

查出来的都是id的list数据
