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.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.setDataSource(dataSource);

factory.setApplicationContextSchedulerContextKey("applicationContext");

// 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。
