java + springboot + 完成疲劳驾驶判定和警告信息生成 代码

在Java中结合Spring Boot开发一个疲劳驾驶判定系统,主要包括几个步骤:
1. **模型层 (Model)**: 创建司机、车辆和驾驶记录等实体类,例如Driver、Vehicle和DrivingLog。其中,驾驶记录可能包含开始时间、结束时间以及驾驶期间的休息次数。
```java
public class DrivingLog {
private Driver driver;
private LocalDateTime startTime;
private LocalDateTime endTime;
private int restTimes;
// getters and setters
}
```
2. **服务层 (Service)**: 实现疲劳驾驶计算逻辑。通过比较连续驾驶时间和总驾驶时间,判断是否超过疲劳驾驶阈值。例如,如果连续驾驶时间超过4小时并且没有足够的休息,就视为疲劳驾驶。
```java
@Service
public class FatigueDetectionService {
public boolean isFatigue(DrivingLog drivingLog) {
long totalDrivingTime = ChronoUnit.MINUTES.between(drivingLog.getStartTime(), drivingLog.getEndTime());
if (totalDrivingTime > FATIGUE_THRESHOLD && drivingLog.getRestTimes() < REST Requirements) {
return true;
}
return false;
}
}
```
3. **控制层 (Controller)**: 使用Spring MVC接收请求,处理Driver对象,并调用疲劳检测服务。
```java
@RestController
@RequestMapping("/driver")
public class DriverController {
@Autowired
private FatigueDetectionService fatigueDetectionService;
@PostMapping("/check-fatigue")
public ResponseEntity<String> checkFatigue(@RequestBody Driver driver) {
DrivingLog log = new DrivingLog(driver);
boolean isFatigued = fatigueDetectionService.isFatigue(log);
String warningMessage = isFatigued ? "警告:驾驶员可能存在疲劳驾驶风险" : "正常驾驶";
return ResponseEntity.ok(warningMessage);
}
}
```
