1、主程序添加注解

import org.springframework.scheduling.annotation.EnableScheduling;@EnableScheduling

 

2、定时任务

可在主程序添加方法，也可在service类添加方法

package com.xiaostudy.shiro_test1.service;import com.xiaostudy.shiro_test1.utils.BackupMysqlUtils;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Service;/** * Created with IntelliJ IDEA. * User: xiaostudy * Date: 2019/7/25 * Time: 22:40 * Description: No Description */@Servicepublic class ScheduledService {    /**     * 定时备份mysql，每天22:42备份     */    @Scheduled(cron = "0 42 22 * * ?")    public void timingBackupMysql() {        BackupMysqlUtils.backup();    }}
