1、添加依赖

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>
        <dependency>

2、继承 QuartzJobBean 类,实现具体的业务逻辑

package com.example.demo.job;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

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

/**
 * @author lyd
 * @Description:
 * @date 17:10
 */

public class HiJob extends QuartzJobBean {

	@Override
	protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {

		// 获取jobDetail中传递的参数
		String userNamge = (String) jobExecutionContext.getJobDetail().getJobDataMap().get("用户名");
		String url = (String) jobExecutionContext.getJobDetail().getJobDataMap().get("url");
		String remark = (String) jobExecutionContext.getJobDetail().getJobDataMap().get("问候语");

		Date date = new Date();
		SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd hh:mm:ss");

		System.out.println();
		System.out.println("用户名:" + userNamge);
		System.out.println("地址:" + url);
		System.out.println("问候语:" + remark);
		System.out.println("时间:" + dateFormat.format(date));
		System.out.println();

	}


}

3、配置定时任务

package com.example.demo.config;

import com.example.demo.job.HiJob;
import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 配置
 *
 * @author lyd
 * @Description:
 * @date 17:29
 */
@Configuration
public class QuartzConfig {

	/**
	 * 工作的组名
	 */
	private final static String JOB_GROUP_NAME = "LIU_JOB_GROUP_NAME";
	/**
	 * 触发组名称
	 */
	private final static String TRIGGER_GROUP_NAME = "LIU_TRIGGER_GROUP_NAME";


	/**
	 * 任务详情
	 * 同步用户的工作细节
	 *
	 * @return {@link JobDetail}
	 */
	@Bean
	public JobDetail syncUserJobDetail() {

		JobDetail jobDetail = JobBuilder
				.newJob(HiJob.class)
				.withIdentity("syncUserJobDetail", JOB_GROUP_NAME)
				.usingJobData("用户名", "这是我的用户名")
				.usingJobData("url", "www.baidu.hhahaahah")
				.usingJobData("问候语", "你好，啦啦啦啊")
				.storeDurably()//持久化，即使没有Trigger关联时也不需要删除该jobdetail
				.build();

		return jobDetail;
	}

	/**
	 * 同步userjob触发
	 * 同步用户信息触发器
	 *
	 * @return {@link Trigger}
	 */
	@Bean
	public Trigger syncUserjobTrigger() {

		// 每5秒执行一次
		CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");

		Trigger trigger = TriggerBuilder.newTrigger()
				.forJob(syncUserJobDetail())//关联上面那个JobDetail
				.withIdentity("我是Trigger的名字", TRIGGER_GROUP_NAME)
				.withSchedule(cronScheduleBuilder)
				.build();

		return trigger;
	}


}
