场景：一个消防栓对应多个硬件设备，

所以需要删除主表数据的同时，也要把子表的数据全部删除

    @Autowired
    private DevicesMapper devicesMapper;
    @Autowired
    private UserMapper userMapper;
    @Autowired
    private OnenetDeviceMapper onenetDeviceMapper;

    /**
     * 批量或单个
     * 逻辑删除消防设备表和硬件设备表的数据
     * 先根据消防设备ID查询出所有硬件设备ID
     */
    @Override
    @Transactional
    public int delete(String[] devicesId){
        for(String str:devicesId){
            String devicesID=str;
            List<OnenetDevice> list=onenetDeviceMapper.findAllDevice(devicesID);
            //创建一个字符串数组,用于存放硬件设备表的所有id
            String [] ids=new String [list.size()];
            //取出集合中的所有id存到数组中
            for(int i=0;i<ids.length; i++){
                ids[i]=list.get(i).getId();
            }
            //逻辑删除硬件表的所有数据
            int result=onenetDeviceMapper.deleteOnenetDevice(ids);
            //物理删除oneNet平台上的数据
            for(OnenetDevice od:list){
                String onenetDevicesId=od.getOnenetDevicesId();
                DeleteDeviceApi api = new DeleteDeviceApi(onenetDevicesId, CommonUtil.key);
                BasicResponse<Void> response = api.executeApi();
                System.out.println("errno:"+response.errno+" error:"+response.error);       
            }   
        }
        //最后逻辑删除消防设备表中的数据
        int iden=devicesMapper.delete(devicesId);
        return iden;
    }

 /**
  * 逻辑删除,可以批量

<!-- 删除 -->
