boot-admin整合Quartz实现动态管理定时任务

淄博烧烤爆红出了圈，当你坐在八大局的烧烤摊，面前是火炉、烤串、小饼和蘸料，音乐响起，啤酒倒满，烧烤灵魂的party即将开场的时候，你系统中的Scheduler（调试器），也自动根据设定的Trigger（触发器），从容优雅的启动了一系列的Job（后台定时任务）。工作一切早有安排，又何须费心劳神呢？因为boot-admin早已将Quartz这块肉串在了烤签上！

Quartz是一款Java编写的开源任务调度框架，同时它也是Spring默认的任务调度框架。它的作用其实类似于Timer定时器以及ScheduledExecutorService调度线程池，当然Quartz作为一个独立的任务调度框架表现更为出色，功能更强大，能够定义更为复杂的执行规则。
boot-admin 是一款采用前后端分离模式、基于 SpringCloud 微服务架构 + vue-element-admin 的 SaaS 后台管理框架。
那么boot-admin怎样才能将Quartz串成串呢？一共分三步：

前端整合

vue页面以el-table作为任务的展示控件，串起任务的创建、修改、删除、挂起、恢复、状态查看等功能。

后端整合

配置类

单独数据源配置

Quartz会自动创建11张数据表，数据源可以与系统主数据源相同，也可以独立设置。

笔者建议单独设置Quartz数据源。在配置文件 application.yml 添加以下内容

base2048:
  job:
    enable: true
    datasource:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/base2048job?useSSL=false&serverTimezone=UTC&autoReconnect=true&allowPublicKeyRetrieval=true&useOldAliasMetadataBehavior=true
      username: root
      password: mysql

数据源配置类如下：

@Configuration
public class QuartzDataSourceConfig {
    @Primary
    @Bean(name = "defaultDataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DruidDataSource druidDataSource() {
        return new DruidDataSource();
    }
    @Bean(name = "quartzDataSource")
    @QuartzDataSource
    @ConfigurationProperties(prefix = "base2048.job.datasource")
    public DruidDataSource quartzDataSource() {
        return new DruidDataSource();
    }
}

调度器配置

在 resources 下添加 quartz.properties 文件，内容如下：

# 固定前缀org.quartz
# 主要分为scheduler、threadPool、jobStore、plugin等部分
#
#
org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false


org.quartz.scheduler.instanceId = 'AUTO'
# 实例化ThreadPool时，使用的线程类为SimpleThreadPool
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
# threadCount和threadPriority将以setter的形式注入ThreadPool实例
# 并发个数
org.quartz.threadPool.threadCount = 15
# 优先级
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
org.quartz.jobStore.misfireThreshold = 5000

# 默认存储在内存中
