Spring配置类

package test.daemon.clusterquartz.config;
import java.io.IOException;
import java.util.Properties;
import java.util.concurrent.Executor;
import javax.sql.DataSource;
import org.quartz.Scheduler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import test.daemon.clusterquartz.quartz.QuartzJob;
@Configuration
public class SchedulerConfig {
  @Autowired
  private DataSource dataSource;
  @Bean
  public Scheduler scheduler() throws Exception {
    Scheduler scheduler = schedulerFactoryBean().getScheduler();
    scheduler.start();
    return scheduler;
  }
  @Bean
  public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
    SchedulerFactoryBean factory = new SchedulerFactoryBean();
    factory.setSchedulerName("Cluster_Scheduler");
    factory.setDataSource(dataSource);
    factory.setApplicationContextSchedulerContextKey("applicationContext");
    factory.setTaskExecutor(schedulerThreadPool());
    factory.setTriggers(trigger1().getObject());
    factory.setQuartzProperties(quartzProperties());
    return factory;
  }
  @Bean

    propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
    // 在quartz.properties中的属性被读取并注入后再初始化对象
    propertiesFactoryBean.afterPropertiesSet();
    return propertiesFactoryBean.getObject();
  }
  @Bean
  public JobDetailFactoryBean job1() {
    JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
    jobDetailFactoryBean.setJobClass(QuartzJob.class);
    jobDetailFactoryBean.setDurability(true);
    jobDetailFactoryBean.setRequestsRecovery(true);
    return jobDetailFactoryBean;
  }
  @Bean
  public CronTriggerFactoryBean trigger1() {
    CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
    cronTriggerFactoryBean.setJobDetail(job1().getObject());
    cronTriggerFactoryBean.setCronExpression("0/3 * * * * ?");
    return cronTriggerFactoryBean;
  }
  @Bean
  public Executor schedulerThreadPool() {
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setCorePoolSize(15);
    executor.setMaxPoolSize(25);
    executor.setQueueCapacity(100);
    return executor;
  }
}

Quartz job类

package test.daemon.clusterquartz.quartz;
import java.util.Date;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.PersistJobDataAfterExecution;
import org.springframework.scheduling.quartz.QuartzJobBean;
@PersistJobDataAfterExecution
@DisallowConcurrentExecution
public class QuartzJob extends QuartzJobBean {
  @Override
  protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
    // TODO Auto-generated method stub
    System.out.println("\nQuartz job " + new Date());
  }
}

Spring Boot启动类

package test.daemon.clusterquartz;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Cluster {
  public static void main(String[] args) throws Exception {
    SpringApplication.run(Cluster.class, args);
  }
}

数据库sql

可以在Quartz的lib中找到适当的数据库生成文件来创建jdbc job store所需要的表。这些表用于Quartz在集群环境中的调度。

一些解释

把项目复制一份，然后改掉spring server的启动端口，启动多个项目，可以观察到只有一个项目的Quartz在运行。如果当前运行Quartz的服务器挂掉，另一台会跟进执行相同的Quartz任务。

有待思考的部分

在Quartz集群环境中，时间的同步是一个重要问题，有时间需要去看一下怎么进行时间同步来确保集群的正确性。
