前言

本次是关于quartz如何整合的一个案例，操作定时任务如何更新，

这个的整合可以先看一看此次所需的文件结构：
在这里插入图片描述

pom配置文件

pom.xml配置

这个只是quartz所需的包

		<!--spring整合所没有的部分-->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>

        <!--被spring整合后的并加了些其他东西-->

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>

总的一个配置可以看看没事，我都打好了注解：

案例展示

后记（配置文件和定时任务原理）

稍微讲下配置文件和定时任务原理吧，
一、配置文件
总的配置文件分为管理数据源、管理scheduler生成的两个部分
在这里插入图片描述

1、管理数据源
其实上面就是我要用的数据源。
enn,只不过就算是之后的运用数据库我们也是用的是druid,如果不是druid的话就没有参考了

druid整合后多了一个quartz接受的整合文件，其实你不搞也行反正quartz内部用的就是c3p0的数据源。
通过定制在quartz.properties文件的配置就可以确定你用的是哪个数据源了
在这里插入图片描述

2、管理scheduler生成

这个就是去把调度器的生成交给spring进行一个管理

在这里插入图片描述
在这里插入图片描述

二、定时任务管理

在下载并运行quartz官方的数据库后就会有一些数据表
那么其实在整合完毕过后的quartz的运行就在使用官方的表，而不是去使用我们的表。
在这里插入图片描述

那么都知道在刚开始的时候官方的表都是空的，每当我们创建一个调度器的时候，其实在同时内部就会向官方表加入数据，此后只要开启服务quartz就会自动开启定时任务，
在这里插入图片描述

我们自己有张表可以显示自己的定时任务详情，那么我们如果就单独的改变自己的表那是没用的。所以我们需要操作官方表，官方表都是自己有方法的，所以我们在刷新，修改，增加，删除的时候都调用一下并检查一下官方表就行了。
详细看上面的ScheduleTriggerServiceImpl
