Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目,它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个,百个,甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或 EJBs。Quartz的最新版本为Quartz 2.3.2。
中文官方文档:https://www.w3cschool.cn/quartz_doc/
1.Job 表示一个工作,要执行的具体内容。
2.JobDetail 表示一个具体的可执行的调度程序,Job 是这个可执行程调度程序所要执行的内容,另外 JobDetail 还包含了这个任务调度的方案和策略。
3.Trigger 代表一个调度参数的配置,什么时候去调。
4.Scheduler 代表一个调度容器,一个调度容器中可以注册多个 JobDetail 和 Trigger。当 Trigger 与 JobDetail 组合,就可以被 Scheduler 容器调度了。

注意:initialize-schema: never,这个属性,第一次生成quartz内置表时设置为always,生成后改为never,不然每次启动系统都会重新生成表。
@SpringBootApplication
@EnableOpenApi
public class QuartzService {
public static void main(String[] args) {
SpringApplication.run(QuartzService.class,args);
}
}
添加启动类后可以运行项目,生成quartz内置表,
生成11张表
包含定时任务添加,修改,运行,暂停,恢复,删除和查询。

因为没有前端页面,我们引入了swagger,运行项目后在浏览器输入
http://localhost:8802/swagger-ui/,出现页面如下
进入定时任务操作接口,先测试添加和修改
添加成功后可以在查询接口查看,不输入任务分组时可以看到设置的定时终止任务
