淄博燒烤爆紅出了圈，當你坐在八大局的燒烤攤，面前是火爐、烤串、小餅和蘸料，音樂響起，啤酒倒?jié)M，燒烤靈魂的party即將開場的時候，你系統(tǒng)中的Scheduler（調試器），也自動根據設定的Trigger（觸發(fā)器），從容優(yōu)雅的啟動了一系列的Job（后臺定時任務）。工作一切早有安排，又何須費心勞神呢？因為boot-admin早已將Quartz這塊肉串在了烤簽上！

Quartz是一款Java編寫的開源任務調度框架，同時它也是Spring默認的任務調度框架。它的作用其實類似于Timer定時器以及ScheduledExecutorService調度線程池，當然Quartz作為一個獨立的任務調度框架表現更為出色，功能更強大，能夠定義更為復雜的執(zhí)行規(guī)則。
boot-admin 是一款采用前后端分離模式、基于 SpringCloud 微服務架構 + vue-element-admin 的 SaaS 后臺管理框架。
那么boot-admin怎樣才能將Quartz串成串呢？一共分三步：

后端整合
配置類
單獨數據源配置
Quartz會自動創(chuàng)建11張數據表，數據源可以與系統(tǒng)主數據源相同，也可以獨立設置。
筆者建議單獨設置Quartz數據源。在配置文件 application.yml 添加以下內容
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
數據源配置類如下：
@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();
}
}
調度器配置
在 resources 下添加 quartz.properties 文件，內容如下：
# 固定前綴org.quartz
# 主要分為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
<!-- 每個集群節(jié)點要有獨立的instanceId -->
org.quartz.scheduler.instanceId = 'AUTO'
# 實例化ThreadPool時，使用的線程類為SimpleThreadPool
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
# threadCount和threadPriority將以setter的形式注入ThreadPool實例
# 并發(fā)個數
org.quartz.threadPool.threadCount = 15
# 優(yōu)先級
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
org.quartz.jobStore.misfireThreshold = 5000
# 默認存儲在內存中
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
#持久化
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = qzDS
org.quartz.dataSource.qzDS.maxConnections = 10
調度器配置類內容如下：
@Configuration
public class SchedulerConfig {

factory.setStartupDelay(20);
// 用于quartz集群,QuartzScheduler 啟動時更新己存在的Job
// factory.setOverwriteExistingJobs(true);
// 加載quartz數據源配置
factory.setQuartzProperties(quartzProperties());
// 自定義Job Factory，用于Spring注入
factory.setJobFactory(myJobFactory);
// 在com.neusoft.jn.gpbase.quartz.job.BaseJobTemplate 同樣出現該配置
//原因 : qrtz 在集群模式下 存在 同一個任務 一個在A服務器任務被分配出去 另一個B服務器任務不再分配的情況.
