SpringBoot定時任務 – 集成quartz實現定時任務（單實例和分散式兩種方式)
- 2022 年 8 月 1 日
- 筆記
- Springboot體系化開發實踐
最為常用定時任務框架是Quartz，並且Spring也集成了Quartz的框架，Quartz不僅支援單實例方式還支援分散式方式。本文主要介紹Quartz，基礎的Quartz的集成案例本，以及實現基於資料庫的分散式任務管理和控制job生命周期。@pdai
準備知識點
需要了解常用的Quartz框架。
什麼是Quartz
來源百度百科, 官網地址：//www.quartz-scheduler.org/
Quartz是OpenSymphony開源組織在Job scheduling領域又一個開源項目，它可以與J2EE與J2SE應用程式相結合也可以單獨使用。Quartz可以用來創建簡單或為運行十個，百個，甚至是好幾萬個Jobs這樣複雜的程式。Jobs可以做成標準的Java組件或 EJBs。
它的特點如下
- 純java實現，可以作為獨立的應用程式，也可以嵌入在另一個獨立式應用程式運行
- 強大的調度功能，Spring默認的調度框架，靈活可配置；
- 作業持久化，調度環境持久化機制，可以保存並恢復調度現場。系統關閉數據不會丟失；靈活的應用方式，可以任意定義觸發器的調度時間表，支援任務和調度各種組合，組件式監聽器、各種插件、執行緒池等功能，多種存儲方式等；
- 分散式和集群能力，可以被實例化，一個Quartz集群中的每個節點作為一個獨立的Quartz使用，通過相同的資料庫表來感知到另一個Quartz應用
Quartz的體系結構
- Job 表示一個工作，要執行的具體內容。
- JobDetail 表示一個具體的可執行的調度程式，Job 是這個可執行程調度程式所要執行的內容，另外 JobDetail 還包含了這個任務調度的方案和策略。
- Trigger 代表一個調度參數的配置，什麼時候去調。
- Scheduler 代表一個調度容器，一個調度容器中可以註冊多個 JobDetail 和 Trigger。當 Trigger 與 JobDetail 組合，就可以被 Scheduler 容器調度了。

什麼是Quartz持久化
- 為什麼要持久化？
當程式突然被中斷時，如斷電，記憶體超出時，很有可能造成任務的丟失。 可以將調度資訊存儲到資料庫裡面，進行持久化，當程式被中斷後，再次啟動，仍然會保留中斷之前的數據，繼續執行，而並不是重新開始。
- Quartz提供了兩種持久化方式
Quartz提供兩種基本作業存儲類型:
- RAMJobStore
在默認情況下Quartz將任務調度的運行資訊保存在記憶體中，這種方法提供了最佳的性能，因為記憶體中數據訪問最快。不足之處是缺乏數據的持久性，當程式路途停止或系統崩潰時，所有運行的資訊都會丟失。
- JobStoreTX
所有的任務資訊都會保存到資料庫中，可以控制事物，還有就是如果應用伺服器關閉或者重啟，任務資訊都不會丟失，並且可以恢復因伺服器關閉或者重啟而導致執行失敗的任務。
實現案例 – 單實例方式
本例將展示quartz實現單實例方式。
- 引入POM依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
- 定義Job
只需要繼承QuartzJobBean，並重載executeInternal方法即可定義你自己的Job執行邏輯。
@Slf4j
public class HelloJob extends QuartzJobBean {
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
// get parameters
context.getJobDetail().getJobDataMap().forEach(
(k, v) -> log.info("param, key:{}, value:{}", k, v)
);
// your logics
log.info("Hello Job執行時間: " + new Date());
}
}
- 配置Job
JobDetail, Trigger, Schedule(這裡採用CronScheduleBuilder)
/**
* @author pdai
*/
@Configuration
public class QuartzConfig {
@Bean("helloJob")
public JobDetail helloJobDetail() {
return JobBuilder.newJob(HelloJob.class)
.withIdentity("DateTimeJob")
.usingJobData("msg", "Hello Quartz")
.storeDurably()//即使沒有Trigger關聯時，也不需要刪除該JobDetail
.build();
}
@Bean
public Trigger printTimeJobTrigger() {
// 每秒執行一次
CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/1 * * * * ?");
return TriggerBuilder.newTrigger()
.forJob(helloJobDetail())
.withIdentity("quartzTaskService")
.withSchedule(cronScheduleBuilder)
.build();
}
}
