- 使用Spring Data JPA存储华为智能门锁开门记录
- 基于Spring Batch处理华为体脂秤历史数据
- 通过Spring Cache缓存华为空气净化器状态
安全认证
- 集成Spring Security与华为账号OAuth2认证
- 使用Spring Session管理华为智能家居多端会话
- 基于Spring Security ACL实现设备访问控制
消息通知
- 通过Spring Mail发送华为烟雾报警器告警邮件
- 集成Spring Cloud Stream处理华为网关设备消息
- 使用Spring WebFlux推送华为摄像头移动侦测通知
数据分析
- 基于Spring Cloud Function处理华为智能电表数据
- 使用Spring GraphQL查询华为环境监测仪历史
- 通过Spring Data Elasticsearch分析华为睡眠监测仪数据
具体实现代码片段
设备状态查询API
@RestController
@RequestMapping("/api/devices")
public class DeviceController {@Autowiredprivate HuaweiDeviceService deviceService;@GetMapping("/{deviceId}/status")public DeviceStatus getStatus(@PathVariable String deviceId) {return deviceService.getDeviceStatus(deviceId);}
}
设备控制命令
@Service
public class HuaweiDeviceService {public void controlDevice(String deviceId, String command) {// 调用华为HiLink API实现设备控制String url = "https://api.huawei.com/device/control";// ...HTTP请求实现...}
}
事件监听处理
@Component
public class DeviceEventListener {@EventListenerpublic void handleMotionEvent(MotionEvent event) {// 处理华为人体传感器事件if(event.getDeviceType().equals("motion_sensor")) {// 触发相关业务逻辑}}
}
开发注意事项
- 华为HiLink平台需要开发者账号申请接入权限
- 设备控制API需要遵循华为的接口规范和安全协议
- 建议使用Spring Retry模块处理网络不稳定的API调用
- 生产环境应考虑使用Spring Cloud Circuit Breaker实现熔断
以上示例展示了Spring框架在华为智能家居系统中的典型应用场景,开发者可根据具体需求选择合适的Spring模块进行扩展开发。
通过Spring Boot REST API控制华为智能灯泡的实例
以下是通过Spring Boot REST API控制华为智能灯泡的实例代码片段,涵盖不同功能场景和华为IoT平台(如华为云IoT或Hilink协议)的集成方式。假设使用华为云的IoT服务作为示例平台。
基础API控制
1. 创建Spring Boot项目并添加依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><groupId>com.huaweicloud.sdk</groupId><artifactId>huaweicloud-sdk-iotda</artifactId><version>3.1.42</version>
</dependency>
2. 配置华为云IoT连接参数
@Configuration
public class HuaweiCloudConfig {@Value("${huawei.cloud.region}")private String region;@Value("${huawei.cloud.ak}")private String ak;@Value("${huawei.cloud.sk}")private String sk;@Beanpublic IoTDAClient iotClient() {return IoTDAClient.newBuilder().withCredential(new BasicCredentials(ak, sk)).withRegion(region).build();}
}
3. 发送开关指令API
@RestController
@RequestMapping("/api/light")
public class LightController {@Autowiredprivate IoTDAClient iotClient;@PostMapping("/{deviceId}/power")public String controlPower(@PathVariable String deviceId, @RequestParam boolean on) {DeviceCommandRequest request = new DeviceCommandRequest().withDeviceId(deviceId).withServiceId("power").withCommandName("switch").withParas(Map.of("value", on ? 1 : 0));iotClient.createCommand(request);return "Command sent";}
}
4. 查询设备状态
@GetMapping("/{deviceId}/status")
public String getStatus(@PathVariable String deviceId) {ShowDeviceRequest request = new ShowDeviceRequest().withDeviceId(deviceId);DeviceDTO response = iotClient.showDevice(request);return response.getStatus().toString();
}
5. 批量控制多个灯泡
@PostMapping("/batch/power")
public String batchControl(@RequestBody List<String> deviceIds, @RequestParam boolean on) {deviceIds.forEach(id -> {controlPower(id, on);});return "Batch command sent";
}
进阶功能示例
6. 定时开关控制
@Scheduled(cron = "0 0 18 * * ?")
public void autoTurnOnAt6PM() {controlPower("device123", true);
}
7. 亮度调节
@PostMapping("/{deviceId}/brightness")
public String setBrightness(@PathVariable String deviceId, @RequestParam int percent) {DeviceCommandRequest request = new DeviceCommandRequest().withDeviceId(deviceId).withServiceId("brightness").withCommandName("set").withParas(Map.of("value", percent));iotClient.createCommand(request);return "Brightness set to " + percent + "%";
}
8. 颜色控制(RGB)
@PostMapping("/{deviceId}/color")
public String setColor(@PathVariable String deviceId, @RequestParam int r, @RequestParam int g, @RequestParam int b) {DeviceCommandRequest request = new DeviceCommandRequest().withDeviceId(deviceId).withServiceId("color").withCommandName("set").withParas(Map.of("red", r, "green", g, "blue", b));iotClient.createCommand(request);return "Color changed";
}
9. 设备分组管理
@PostMapping("/group/{groupId}/power")
public String controlGroup(@PathVariable String groupId, @RequestParam boolean on) {List<String> deviceIds = getDevicesByGroup(groupId);return batchControl(deviceIds, on);
}
10. 场景联动(与其他设备)
@PostMapping("/scene/movie-mode")
public String activateMovieMode() {controlPower("living-room-light", false);setBrightness("tv-backlight", 30);return "Scene activated";
}
安全与错误处理
11. API密钥加密存储
@Bean
public IoTDAClient iotClient() throws Exception {String decryptedAk = decrypt(encryptedAk);String decryptedSk = decrypt(encryptedSk);return IoTDAClient.newBuilder().withCredential(new BasicCredentials(decryptedAk, decryptedSk)).build();
}
12. 请求验证
@PostMapping("/{deviceId}/power")
public ResponseEntity<?> controlPower(@RequestHeader("X-API-Key") String apiKey,@PathVariable String deviceId,@RequestParam boolean on) {if (!validApiKey(apiKey)) {return ResponseEntity.status(401).build();}// ...原有逻辑
}
