在Application启动类上添加@EnableScheduling注解启动定时
@SpringBootApplication(scanBasePackages = "com.xx.test")
@MapperScan("com.xx.test.dao")
@EnableScheduling
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
使用@Component和@Scheduled(cron="0 0/5 * * * ?")启动定时任务
//@Compoment注解将定时任务类纳入spring bean管理
@Component
public class DemoScheduledTask{
@Scheduled(cron="0 0/5 * * * ?")
public void test1() {
System.out.println("每5分钟执行一次");
}
@Scheduled(cron="0 0 23 * * ?")
public void test2() {
System.out.println("每天23点执行一次");
}
@Scheduled(fixedRate=30000)
public void test3() {
System.out.println("每30秒执行一次");
}
}
这样就可以启动定时任务了
