        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            wrapper.and((w)->{
                w.eq("id",key).or().like("spu_name",key);
            });
        }
        // status=1 and (id=1 or spu_name like xxx)
        String status = (String) params.get("status");
        if(!StringUtils.isEmpty(status)){
            wrapper.eq("publish_status",status);
        }

        String brandId = (String) params.get("brandId");
        if(!StringUtils.isEmpty(brandId)&&!"0".equalsIgnoreCase(brandId)){
            wrapper.eq("brand_id",brandId);
        }

        String catelogId = (String) params.get("catelogId");
        if(!StringUtils.isEmpty(catelogId)&&!"0".equalsIgnoreCase(catelogId)){
            wrapper.eq("catalog_id",catelogId);
        }

        /**
         * status: 2
         * key:
         * brandId: 9
         * catelogId: 225
         */

        IPage page = this.page(
                new Query().getPage(params),
                wrapper
        );

        return new PageUtils(page);
