SpringBoot（二）集成 Quartz:2.5.4

Quartz是一个广泛使用的开源任务调度框架，用于在Java应用程序中执行定时任务和周期性任务。它提供了强大的调度功能，允许您计划、管理和执行各种任务，从简单的任务到复杂的任务。

以下是Quartz的一些关键特点和功能：

灵活的调度器：Quartz提供了一个高度可配置的调度器，允许您根据不同的时间表执行任务，包括固定的时间、每日、每周、每月、每秒等。您可以设置任务执行的时间和频率。
多任务支持：Quartz支持同时管理和执行多个任务。您可以定义多个作业和触发器，并将它们添加到调度器中。
集群和分布式调度：Quartz支持集群模式，可以在多台机器上协调任务的执行。这使得Quartz非常适合大规模和分布式应用，以确保任务的高可用性和负载均衡。
持久化：Quartz可以将任务和调度信息持久化到数据库中，以便在应用程序重启时不会丢失任务信息。这对于可靠性和数据保持非常重要。
错过任务处理：Quartz可以配置在任务错过执行时如何处理，例如，是否立即执行、延迟执行或丢弃任务。
监听器：Quartz提供了各种监听器，可以用来监视任务的执行，以及在任务执行前后执行自定义操作。
多种作业类型：Quartz支持不同类型的作业，包括无状态作业（Stateless Job）和有状态作业（Stateful
Job）。这允许您选择最适合您需求的作业类型。
插件机制：Quartz具有灵活的插件机制，可以扩展其功能。您可以创建自定义插件，以满足特定需求。
丰富的API：Quartz提供了丰富的Java API，使任务调度的配置和管理非常方便。
