    @Override
    public void deleteRelation(AttrGroupRelationVo vos) {
        //将我们接受数据的对象转为一个 entity
        List<AttrAttrgroupRelationEntity> list = Arrays.asList(vos).stream().map((item) -> {
            AttrAttrgroupRelationEntity entity = new AttrAttrgroupRelationEntity();
            BeanUtils.copyProperties(item, entity);
            return entity;
        }).collect(Collectors.toList());
        //批量的删关联表中的数据
        attrAttrgroupRelationDao.removeBatchRelation(list);
    }

 

通过一个ID 获取其父级别 组装为  [1,2,4]    

@Override
    public Long[] findCatelogPath(Long catelogId) {
        List<Long> paths = new ArrayList<>();
        List<Long> parentPath = findParentPath(catelogId,paths);
        Collections.reverse(parentPath);
        return  parentPath.toArray(new Long[parentPath.size()]);
    }

    private List<Long> findParentPath(Long catelogId, List<Long> paths) {
        paths.add(catelogId);
        CategoryEntity entity = this.getById(catelogId);
        if(entity.getParentCid() != 0){
            findParentPath(entity.getParentCid(),paths);
        }
        return paths;
    }
