导入依赖

<dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId></dependency>

对方法添加注解

@Scheduled(cron = "*/2 * * * * ?") 
public void scheduledMethod() { // 设置为两秒启动一次 }

开启注解支持

@SpringBootApplication
@EnableScheduling
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}}
