注解 @Scheduled(cron = “0/5 * * * * ?”)

相当于原来的xml版本的如下配置

<task:scheduled ref="scheduledTask" method="getTask1" cron="0/5 * * * * ?" />

ScheduledTask

package com.jege.spring.boot.task;

import java.text.SimpleDateFormat;

import java.util.Date;

import org.springframework.scheduling.annotation.Scheduled;

import org.springframework.stereotype.Component;

/**

 */

@Component

public class ScheduledTask {

  private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

  @Scheduled(fixedDelayString = "${jobs.fixedDelay}")

  public void getTask1() {

    System.out.println("任务1,从配置文件加载任务信息，当前时间：" + dateFormat.format(new Date()));

  }

  @Scheduled(cron = "${jobs.cron}")

  public void getTask2() {

    System.out.println("任务2,从配置文件加载任务信息，当前时间：" + dateFormat.format(new Date()));

  }

}

application.properties

jobs.fixedDelay=5000

jobs.cron=0/5 * *  * * ?

Application.java

package com.jege.spring.boot;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.scheduling.annotation.EnableScheduling;

/**

 */

@SpringBootApplication

@EnableScheduling

public class Application {

  public static void main(String[] args) {

    SpringApplication.run(Application.class, args);

  }

}
