定时任务代码

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;

@Component
public class Timeer {

    @Scheduled(cron = "5 * * * * ?")
public void timer(){
    System.out.println(1);
}

}

application.xml

  <!--使用定时任务注解-->
    <task:annotation-driven/>

可通过在线生成Cron表达式的工具：http://cron.qqe2.com/ 来生成自己想要的表达式。
运行tomcat就看到效果了
