如何使用SpringBoot实现定时任务？

@SpringBootApplication
@EnableScheduling  // 启用定时任务功能
public class SpringBootScheduledApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootScheduledApplication.class, args);
    }
}

@Component
public class ScheduledTask {

    // 每5秒执行一次
    @Scheduled(fixedRate = 5000)
    public void runFixedRateTask() {
        System.out.println("Fixed Rate Task - " + System.currentTimeMillis());
    }

    // 上一个任务完成后延迟5秒执行
    @Scheduled(fixedDelay = 5000)
    public void runFixedDelayTask() {
        System.out.println("Fixed Delay Task - " + System.currentTimeMillis());
    }
}

@Component
public class ScheduledTask {

    // 每天中午12点执行
    @Scheduled(cron = "0 0 12 * * ?")
    public void runCronTask() {
        System.out.println("Cron Task - " + System.currentTimeMillis());
    }
}

@Component
public class DynamicScheduledTask {

    private int interval = 5000;

    // 动态间隔执行任务
    @Scheduled(fixedRateString = "#{dynamicScheduledTask.interval}")
    public void runDynamicTask() {
        System.out.println("Dynamic Task - " + System.currentTimeMillis());
    }

    public void setInterval(int interval) {
        this.interval = interval;
    }
}

@Configuration
@EnableScheduling
public class TaskSchedulerConfig {

    @Bean
    public TaskScheduler taskScheduler() {
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(10);  // 设置线程池大小
        scheduler.setThreadNamePrefix("Scheduled-Task-");  // 设置线程名称前缀
        scheduler.setDaemon(true);  // 设置为守护线程
        return scheduler;
    }
}

@Component
public class ConditionalScheduledTask {

    @Scheduled(cron = "0 0/5 * * * ? ", zone = "GMT+8", enabled = false)
    public void task() {
        System.out.println("This task won't run because it's disabled.");
    }
}

@Component
public class ErrorHandlingScheduledTask {

    @Scheduled(fixedRate = 5000)
    public void task() {
        try {
            // 执行任务代码
            System.out.println("Running task...");
            if (Math.random() > 0.5) {
                throw new RuntimeException("Task failed!");
            }
        } catch (Exception e) {
            System.err.println("Error occurred: " + e.getMessage());
        }
    }
}
