SpringBoot 多线程定时任务
在 SpringBoot 启动类中添加
@EnableScheduling
@EnableScheduling
@SpringBootApplication
public class CronDemoApplication {
public static void main(String[] args) {
SpringApplication.run(CronDemoApplication.class, args);
}
}
定义类实现
SchedulingConfigurer
@Configuration
public class ScheduleConfig implements SchedulingConfigurer {
@Override
public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
scheduledTaskRegistrar.setScheduler(Executors.newScheduledThreadPool(20));
}
}
定义定时器类
@Slf4j
@Component
public class CronApplication {
@Scheduled(cron = "0/1 * * * * ?")
public void runOne() throws InterruptedException {
log.info("runOne:start");
Thread.sleep(1000 * 10);
log.info("runOne:end");
}
@Scheduled(cron = "0/1 * * * * ?")
public void runTwo() throws InterruptedException {
log.info("runTwo:start");
Thread.sleep(1000 * 5);
log.info("runTwo:end");
}
}
- 注意如果定时器没执行需要检查
- 检查springboot启动类中是否有加
@EnableScheduling - 检查定时器类是否存在springboot容器中, 如果没有在类上添加
@Component
