??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。官网地址:https://www.quartz-scheduler.org/
特点如下:
Scheduler(任务调度器):实际执行任务调度的控制器,在spring中通过SchedulerFactoryBean封装起来
Trigger(触发器): 任务的触发,触发器有SimpleTrigger,CronTrigger,DateIntervalTrigger和NthIncludedDayTrigger四种类型,其中SimpleTrigger:能够周期性的设置任务触发;CronTrigger:使用cron表达式的方式实现任务触发,实现更多样,使用场景也是最多的。其中任务和触发器的关系是:一个任务可以有多个触发器,一个触发器只能对应一个任务。
JobDetail(定时任务的信息载体): 业务需要执行的任务操作,实现Job接口,或者继承QuartzJobBean,实现/重写里面的方法。
为什么要持久化?
??当程序突然被中断时,如断电,内存超出时,很有可能造成任务的丢失。 可以将调度信息存储到数据库里面,进行持久化,当程序被中断后,再次启动,仍然会保留中断之前的数据,继续执行,而并不是重新开始。
提供了两种存储方式:
本示例:采用了springboot已经整合了quartz,如果用户是自己单独集成的,类似这样
可寻找其他示例。

里面依赖了quartz的starter,以及mysql数据库,引入数据库的依赖目的是在于,后续quartz的job,trigger等,以及集群相关配置用到的锁,来控制任务集群模式下的重复执行等信息都是需要保存到数据库的,默认是放在内存中,内存中不利于管理,使用quartz的意义就不明显了。

这个类就是继承的QuartzJobBean,当然也可以实现Job接口,这个类就是任务需要具体执行的业务操作类,类上面添加了两个注解,这两个注解的目的就是让同一个任务必须在上一个任务执行完毕之后再按照触发后续执行,以及定时任务里面的JobDataMap,能够在任务中流转以及修改更新;不添加注解的情况下,JobDataMap里面的数据不能在任务之间流转,以及任务的触发不会参照上一任务是否执行完毕。

具体参考:
由于项目里面是以前的老代码,老代码使用的是,下图方式
导致在application.yml配置的是不生效的。
1.原因:在Quartz发布的JAR包的org.quartz包下,包含了一个命名为quartz.properties的配置文件并提供了默认属性,如果需要调整默认配置,则可以在类路径下建立一个新的quartz.properties,它将自动被Quartz加载并覆盖默认值。如果使用yml格式的配置,由于配置文件加载优先级的原因会导致quartz.properties里面的配置失效。
2.解决办法:所以用户自定义quartz.properties,然后在配置中去手动加载接口。
