springmvc使用注解实现非阻塞定时器

1、在Spring配置文件中添加

xmlns:task="http://www.springframework.org/schema/task"


http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.2.xsd

<context:component-scan base-package="lct.conference.timer" />
<!-- 开启注解调度支持 @Async异步-->
<task:executor id="executor" pool-size="5" />
<task:annotation-driven executor="executor"/>

 2、

package lct.conference.timer;

import lct.conference.util.PCMSLog;
import org.springframework.context.annotation.Lazy;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@EnableAsync
@Lazy(false)//避免spring懒加载导致无效
@Component
public class FlightTrainTask {
    PCMSLog pcmsLog = PCMSLog.getlog(getClass());
    @Async//开启异步，避免阻塞
    @Scheduled(cron = "0/5 * * * * ? ") // 间隔5秒执行
    public void taskCycle() throws InterruptedException {
        Thread.sleep(1000*10);
        pcmsLog.info("=======================使用SpringMVC框架配置定时任务");
    }
}
