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：
加入依赖

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
<!-- 每个集群节点要有独立的instanceId -->
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
#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
调度器配置类内容如下：
@Configuration
public class SchedulerConfig {
@Autowired
private MyJobFactory myJobFactory;
@Value("${base2048.job.enable:false}")
private Boolean JOB_LOCAL_RUNING;
@Value("${base2048.job.datasource.driver-class-name}")

factory.setOverwriteExistingJobs(true);
// 延时启动
factory.setStartupDelay(20);
// 用于quartz集群,QuartzScheduler 启动时更新己存在的Job
// factory.setOverwriteExistingJobs(true);
// 加载quartz数据源配置
factory.setQuartzProperties(quartzProperties());
// 自定义Job Factory，用于Spring注入
factory.setJobFactory(myJobFactory);
// 在com.neusoft.jn.gpbase.quartz.job.BaseJobTemplate 同样出现该配置
//原因 : qrtz 在集群模式下 存在 同一个任务 一个在A服务器任务被分配出去 另一个B服务器任务不再分配的情况.
//
if(!JOB_LOCAL_RUNING){
// 设置调度器自动运行
factory.setAutoStartup(false);
}
return factory;
