springboot整合quartz达到动态配置定时任务的效果

如题：

首先贴上maven的配置

dao层和mybatis的配置crud就不贴了 就简单的增删改查，重点是得和quartz整合

再贴上quartz的两个配置类

测试案例需要的controller

好，最后贴上咱们执行定时任务的类   完事开始测试案例

package com.hw.task;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.stereotype.Component;
import org.thymeleaf.util.DateUtils;

import java.util.Random;

/**
 * @program: bootdo-job
 * @description:
 * @author: hw
 * @create: 2019-09-14 14:28
 **/
@Component
public class test implements Job {
    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {

        System.err.println(new Random().nextInt()+"---"+ System.currentTimeMillis()/1000);
    }
}

然后咱们停止后修改一下cron表达式然后再启动(贴上生成网址:​​http://cron.qqe2.com/​​)
