- 在 ITWTempertureDataService 接口中添加 selectLastTWTempertureDataList 方法- 在 TWTempertureDataController 中添加 selectLastTWTempertureDataList 控制器方法
- 在 TWTempertureDataMapper 接口中添加 selectLastTWTempertureDataList 方法
- 在 TWTempertureDataMapper.xml 中添加 selectLastTWTempertureDataList 的 SQL 查询语句- 在 TWTempertureDataServiceImpl 中实现 selectLastTWTempertureDataList 方法

该功能允许用户查询物联网实时分组最新数据列表，即每个监控点的最新一条记录。
