Spring Boot提供了對(duì)Quartz任務(wù)調(diào)度框架的整合支持。Quartz是一個(gè)功能強(qiáng)大的任務(wù)調(diào)度框架,可以用于定時(shí)執(zhí)行任務(wù)、計(jì)劃任務(wù)等。

要整合Quartz,首先需要添加Quartz的依賴。在pom.xml文件中添加以下依賴:

<!-- Quartz -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
</dependency>

接下來(lái),創(chuàng)建一個(gè)Quartz的配置類,用于配置Quartz的相關(guān)屬性和任務(wù)調(diào)度。

@Configuration
public class QuartzConfig {

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() {
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        
        // 設(shè)置觸發(fā)器
        schedulerFactoryBean.setTriggers(trigger1().getObject(), trigger2().getObject());
        
        // 設(shè)置任務(wù)
        schedulerFactoryBean.setJobDetails(jobDetail1().getObject(), jobDetail2().getObject());
        
        // 設(shè)置自動(dòng)啟動(dòng)
        schedulerFactoryBean.setAutoStartup(true);
        
        return schedulerFactoryBean;
    }
    
    @Bean
    public JobDetailFactoryBean jobDetail1() {
        JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
        jobDetailFactoryBean.setJobClass(MyJob1.class);
        jobDetailFactoryBean.setDurability(true);
        jobDetailFactoryBean.setRequestsRecovery(true);
        return jobDetailFactoryBean;
    }
    
    @Bean
    public JobDetailFactoryBean jobDetail2() {
        JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
        jobDetailFactoryBean.setJobClass(MyJob2.class);
        jobDetailFactoryBean.setDurability(true);
        jobDetailFactoryBean.setRequestsRecovery(true);
        return jobDetailFactoryBean;
    }
    
    @Bean
    public CronTriggerFactoryBean trigger1() {
        CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
        cronTriggerFactoryBean.setJobDetail(jobDetail1().getObject());
        cronTriggerFactoryBean.setCronExpression("0/5 * * * * ?");
        return cronTriggerFactoryBean;
    }
    
    @Bean
    public CronTriggerFactoryBean trigger2() {
        CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
        cronTriggerFactoryBean.setJobDetail(jobDetail2().getObject());
        cronTriggerFactoryBean.setCronExpression("0/10 * * * * ?");
        return cronTriggerFactoryBean;
    }
}

在上面的配置類中,我們創(chuàng)建了兩個(gè)JobDetail和兩個(gè)CronTrigger,并將它們添加到SchedulerFactoryBean中。這樣,當(dāng)應(yīng)用啟動(dòng)時(shí),Quartz會(huì)根據(jù)配置的觸發(fā)器和任務(wù)來(lái)執(zhí)行定時(shí)任務(wù)。

最后,創(chuàng)建兩個(gè)Job類,用于處理具體的任務(wù)邏輯。

public class MyJob1 implements Job {
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        // 任務(wù)邏輯
    }
}

public class MyJob2 implements Job {
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        // 任務(wù)邏輯
    }
}

這樣,就完成了Spring Boot整合Quartz任務(wù)調(diào)度框架的配置。

如果需要將任務(wù)調(diào)度的配置進(jìn)行持久化,可以使用Quartz提供的JobStore來(lái)實(shí)現(xiàn)。常用的JobStore有以下幾種:

  • RAMJobStore:將任務(wù)調(diào)度的配置保存在內(nèi)存中,應(yīng)用關(guān)閉后數(shù)據(jù)將丟失。
  • JDBCJobStore:將任務(wù)調(diào)度的配置保存在數(shù)據(jù)庫(kù)中,應(yīng)用關(guān)閉后數(shù)據(jù)仍然存在。
  • JobStoreCMT:將任務(wù)調(diào)度的配置保存在數(shù)據(jù)庫(kù)中,并且支持容器管理的事務(wù)。

要使用JDBCJobStore進(jìn)行持久化配置,可以添加以下依賴:

<!-- Quartz JDBC -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz-jdbc</artifactId>
</dependency>

<!-- H2 Database -->
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
</dependency>

接著,在Quartz的配置類中添加以下代碼:

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
    // ...
    
    // 設(shè)置持久化配置
    schedulerFactoryBean.setDataSource(dataSource());
    schedulerFactoryBean.setJobFactory(jobFactory());
    
    return schedulerFactoryBean;
}

@Bean
public DataSource dataSource()
