Spring Boot之定时任务@Scheduled

项目中需要用到定时任务，用spring boot实，demo如下：

1.启动程序增加@EnableScheduling注解，开启定时任务。

@SpringBootApplication
@EnableScheduling
public class MerchantCenterApplication {

　　public static void main(String[] args) {
　　　　SpringApplication.run(MerchantCenterApplication.class, args);
　　}
}

2.写测试类

@Component
public class ScheduleTask {

　　@Scheduled(cron = "0/5 * * * * ? ")
　　public void printSay() {
　　　　System.out.println("This is a say method!"+new Date());
　　}
}

3.启动程序，控制台输出

This is a say method!Tue Jul 10 14:00:20 CST 2018
This is a say method!Tue Jul 10 14:00:25 CST 2018
This is a say method!Tue Jul 10 14:00:30 CST 2018
This is a say method!Tue Jul 10 14:00:35 CST 2018
This is a say method!Tue Jul 10 14:00:40 CST 2018
This is a say method!Tue Jul 10 14:00:45 CST 2018
This is a say method!Tue Jul 10 14:00:50 CST 2018

完成！
