springboot之quartz动态可控定时任务
Quartz
Quartz是一个开源的任务调度框架，可以用来实现定时任务的调度，如定时发送邮件、定时备份数据等。Quartz具有很高的可靠性和灵活性，支持集群部署和分布式调度，并且提供了丰富的API和插件，可以轻松实现复杂的调度需求。Quartz的工作原理是通过Job和Trigger两个核心概念来实现的，Job是具体需要执行的任务，Trigger用来触发任务的执行时机。在Quartz中，可以通过定义各种Trigger来实现不同的调度策略，如简单调度、Cron调度等。Quartz还提供了很多内置的Job和Trigger实现，如邮件发送、HTTP请求等，可以方便地用来实现常见的任务调度需求。
核心
Quartz的核心组件包含Scheduler、Job和Trigger。这三个核心组件共同组成了Quartz的任务调度机制，使得开发人员可以通过配置简单的定时任务来实现复杂的调度策略。
Scheduler
是Quartz的核心组件，它负责调度和执行任务。Scheduler有一个任务管理器，负责维护任务列表，并根据Triggers的定义来决定何时执行任务。Scheduler还提供了API，通过API可以动态地添加、删除和修改任务。
-
管理作业：Scheduler负责管理Quartz中的所有作业，包括创建、修改和删除作业。
-
触发器管理：Scheduler负责管理Quartz中的所有触发器，包括创建、修改和删除触发器。
-
作业执行：Scheduler负责执行Quartz中的所有作业，并记录作业执行情况。
-
调度管理：Scheduler负责管理Quartz的整个调度过程，包括启动调度器、暂停调度器和恢复调度器。
-
监控和统计：Scheduler提供了各种监控和统计信息，以帮助开发人员了解Quartz的运行状况。
Job
Job是一个接口，它定义了需要执行的逻辑，开发人员需要实现该接口，并在其中编写需要执行的业务逻辑。
Trigger
Trigger是一个定义了任务执行时间的对象，Quartz提供了多种类型的Trigger，例如
-
SimpleTrigger：简单触发器，用于在指定时间执行一次或者按照指定的时间间隔重复执行。
-
CronTrigger：Cron触发器，用于按照类似于Unix/Linux系统中Cron表达式的方式指定复杂的时间计划，例如每周五下午五点执行。
-
CalendarIntervalTrigger：日历间隔触发器，用于按照在指定时间间隔内执行的时间计划，例如每隔一小时执行一次。
-
DailyTimeIntervalTrigger：每日时间间隔触发器，用于按照每日指定时间间隔执行的时间计划，例如每天上午10点和下午3点各执行一次。

以上就是一个完整的demo了
运行之后访问http://127.0.0.1:8080/doc.html
可以看到我们开放的api
测试
执行以上的sql，有可以看到我内置的一些拿来测试的任务
然后我随便找一个任务开启
当任务状态为0的时候，该任务就是正常的运行中的状态
当然你也可以控制一下，当服务关闭时，去把所有为0状态重置为1，把任务关闭掉，或者当服务重启时，去初始化把状态为0的任务加入执行器中，不然每次重启，任务都不在执行器中与数据库的状态不一致
例如：
@PreDestroy
public void stop() {
stopTask();
}
public void stopTask() {
List jobs = sysJobService.list().stream()
.map(s -> {
s.setStatus("1");
return s;
})
.collect(Collectors.toList());
sysJobService.saveOrUpdateBatch(jobs);
}
