Spring Boot scheduled task of the task management

First, add the service class ScheduledTaskService

package com.uos.schedule.service;


import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

import java.text.SimpleDateFormat;
import java.util.Date;

@Service
public class ScheduledTaskService {
    private static final SimpleDateFormat simpleDataFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private Integer count1 = 1;
    private Integer count2 = 1;
    private Integer count3 = 1;

    @Scheduled (fixedRate = 60000 )
     public  void scheduledTaskImmediately () { 
        System.out.println (String.format ( "% s of fixedRate execution, when time is:% s", count1 is ++, simpleDataFormat.format ( new new a Date ()) )); 
    } 


    @Scheduled (fixedRate = 60000 )
     public  void scheduledTaskAfterSleep () { 
        System.out.println (String.format ( "% s of FIXEDDELAY execution, when time is:% s", count2 ++, simpleDataFormat.format ( new new DATE ()))); 
    } 

    @Scheduled (the cron = "* * * * * 0" )
     public  void scheduledTaskCron () {
        System.out.println (String.format ( "% s of execution Cron, when time is:% s", count3 ++, simpleDataFormat.format ( new new a Date ()))); 
    } 
}

Second, add annotations in the main class @EnableScheduling

 

 Third, the test results
