quartz是一个很强大的任务调度插件，上一节已经讲述了springBoot自带的任务调度功能，但是只能满足简单的需求，集成quartz是为了满足更复杂的需求，比如需要执行的任务存到数据库中保存，包括配置任务信息触发器信息等，再比如需要对执行的任务随时暂停，删除，修改执行频率，执行参数等，而且也要随时添加新的任务去执行，这种复杂的需求下，简单的线程池或者定时任务就很难满足需求，所以就需要quartz来方便我们的使用。
虽然quartz很强大感觉很复杂，但是使用起来其实很简单的。
quartz表结构如下，mysql的数据库

1、在pom中添加quartz的依赖
org.springframework.boot spring-boot-starter-quartz
2、在项目中创建一个util包，并编写一个任务调度关联工具类，对job增删改查等操作

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

}

3、在项目中创建一个task包，用来编写需要执行的任务类
package com.apgblogs.springbootstudy.task;
import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.quartz.QuartzJobBean;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* @author xiaomianyang
* @description
* @date 2019-07-16 16:07
*/
public class TaskOne extends QuartzJobBean {
private final Logger logger= LoggerFactory.getLogger(TaskOne.class);
@Override
protected void executeInternal(JobExecutionContext jobExecutionContext) {
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
logger.info("任务1执行:{}",simpleDateFormat.format(new Date()));
}
}
4、在配置文件中修改quartz的存储类型为jdbc，默认是内存存储
...... quartz: job-store-type: jdbc ......
5、编写测试用例
由于测试用例直接就跑完了，所以休眠个一段时间，就可以看到任务输出了，每秒输出一次，这里的先进行了删除，如果任务已经有了就可以删除重新添加，跟数据库是同步的，实时修改和创建任务数据
@Test
public void addJob() throws Exception{
quartzJobUtil.deleteJob("我的job","task");
quartzJobUtil.addJob(TaskOne.class,"我的job","task","* * * * * ?");
Thread.sleep(100000);
}
@Test
public void pauseJob(){
quartzJobUtil.pauseJob("我的job","task");
}
6、可以启动测试看看结果
测试结果
7、文章源码地址
关注+转发后私信我源码地址，感谢支持
quartz就已经集成上去了，有任何需要定时执行或者由用户手动创建添加的任务都可以用quartz实现，采用的数据库存储，对于已经添加好的job也就不用在重新添加了，只要项目每次启动就会根据定时计划继续执行，对jobDetail表映射实体类，也可以用jpa去查询任务信息，是不是很方便呢。
