1、在Spring配置檔案中新增

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" />
<!-- 開啟註解排程支援 @Async非同步-->
<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懶載入導致無效
@Component
public class FlightTrainTask {
    PCMSLog pcmsLog = PCMSLog.getlog(getClass());
    @Async//開啟非同步，避免阻塞
    @Scheduled(cron = "0/5 * * * * ? ") //
 
 間隔5秒執行
    public void taskCycle() throws InterruptedException {
        Thread.sleep(1000*10);
        pcmsLog.info("=======================使用SpringMVC框架配置定時任務");
    }
}
