SpringBoot整合Quartz 实现分布式定时任务调度

一、Quartz 集群架构
Quartz 是 Java 领域最著名的开源任务调度工具。

在上篇文章中,我们详细的介绍了 Quartz 的单体应用实践,如果只在单体环境中应用,Quartz 未必是最好的选择,例如Spring Scheduled一样也可以实现任务调度,并且与SpringBoot无缝集成,支持注解配置,非常简单,但是它有个缺点就是在集群环境下,会导致任务被重复调度!

而与之对应的 Quartz 提供了极为广用的特性,如任务持久化、集群部署和分布式调度任务等等,正因如此,基于 Quartz 任务调度功能在系统开发中应用极为广泛!

在集群环境下,Quartz 集群中的每个节点是一个独立的 Quartz 应用,没有负责集中管理的节点,而是通过数据库表来感知另一个应用,利用数据库锁的方式来实现集群环境下进行并发控制,每个任务当前运行的有效节点有且只有一个!

 

特别需要注意的是:分布式部署时需要保证各个节点的系统时间一致!

 二、数据表初始化
数据库表结构官网已经提供,我们可以直接访问Quartz对应的官方网站,找到对应的版本,然后将其下载!

 

 我选择的是quartz-2.3.0-distribution.tar.gz,下载完成之后将其解压,在文件中搜索sql,在里面选择适合当前环境的数据库脚本文件,然后将其初始化到数据库中即可!

 

例如,我使用的数据库是mysql-5.7,因此我选择的是tables_mysql_innodb.sql脚本,具体内容如下:

其中,QRTZ_LOCKS 就是 Quartz 集群实现同步机制的行锁表!

三、Quartz 集群实践

1、引入quartz依赖


        
            org.springframework.boot
            spring-boot-starter-quartz
        

 2、创建 application.properties 配置文件,再配置文件中加入quartz配置

#调度配置
org:
  quartz:
    scheduler:
      #调度器实例名称
      instanceName: MaterialFromEamScheduler
      #调度器实例编号自动生成
      instanceId: AUTO
      #是否在Quartz执行一个job前使用UserTransaction
      wrapJobExecutionInUserTransaction: false
#线程池配置
    threadPool:
      #线程池的实现类
      class: org.quartz.simpl.SimpleThreadPool
      #线程池中的线程数量
      threadCount: 10
      #线程优先级
      threadPriority: 5
      #配置是否启动自动加载数据库内的定时任务,默认true
      threadsInheritContextClassLoaderOfInitializingThread: true
    #持久化方式配置
    jobStore:
      #JobDataMaps是否都为String类型
      useProperties: true
      #数据表的前缀,默认QRTZ_
      tablePrefix: QRTZ_
      #最大能忍受的触发超时时间
      misfireThreshold: 60000
      #是否以集群方式运行
      isClustered: true
      #调度实例失效的检查时间间隔,单位毫秒
      clusterCheckinInterval: 2000
      maxMisfiresToHandleAtATime: 1
      #数据保存方式为数据库持久化
      class: org.quartz.impl.jdbcjobstore.JobStoreTX
      #数据库代理类,一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以满足大部分数据库
      driverDelegateClass: org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
      # 是否开启悲观锁控制集群中trigger并发
      acquireTriggersWithinLock: true
      #数据库别名 随便取
      dataSource: qzDS
      #数据库连接池,将其设置为druid
    dataSource:
      qzDS:
        connectionProvider:
          class: com.mes.material.quartz.provider.DruidConnectionProvider
        #数据库引擎
        driver: org.postgresql.Driver
        #数据库连接
        URL: jdbc:postgresql://127.0.0.1:5432/mes_cloud_stag_yqs?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
        #数据库用户
        user: postgres
        #数据库密码
        password: postgres
        #允许最大连接
        maxConnection: 100

3、注册 Quartz 任务工厂

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
import org.springframework.stereotype.Component;

@Component
public class QuartzJobFactory extends AdaptableJobFactory {

    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        //调用父类的方法
        Object jobInstance = super.createJobInstance(bundle);
        //进行注入
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

4、注册调度工厂

本文采用自定义数据源实现




import com.mes.material.constants.MaterialConstants;
import com.mes.material.quartz.factory.QuartzJobFactory;
import com.mes.material.quartz.listener.SimpleJobListener;
import com.mes.material.quartz.listener.SimpleSchedulerListener;
import com.mes.material.quartz.listener.SimpleTriggerListener;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.impl.matchers.EverythingMatcher;
import org.quartz.impl.matchers.KeyMatcher;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import javax.sql.DataSource;
import java.io.IOException;
import java.util.Properties;

        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getMaxConnection() {
        return maxConnection;
    }

    public void setMaxConnection(int maxConnection) {
        this.maxConnection = maxConnection;
    }

    public String getValidationQuery() {
        return validationQuery;
    }

    public void setValidationQuery(String validationQuery) {
        this.validationQuery = validationQuery;
    }

    public boolean isValidateOnCheckout() {
        return validateOnCheckout;
    }

    public void setValidateOnCheckout(boolean validateOnCheckout) {
        this.validateOnCheckout = validateOnCheckout;
    }

    public int getIdleConnectionValidationSeconds() {
        return idleConnectionValidationSeconds;
    }

    public void setIdleConnectionValidationSeconds(int idleConnectionValidationSeconds) {
        this.idleConnectionValidationSeconds = idleConnectionValidationSeconds;
    }

    public DruidDataSource getDatasource() {
        return datasource;
    }

    public void setDatasource(DruidDataSource datasource) {
        this.datasource = datasource;
    }

    public String getDiscardIdleConnectionsSeconds() {
        return discardIdleConnectionsSeconds;
    }

    public void setDiscardIdleConnectionsSeconds(String discardIdleConnectionsSeconds) {
        this.discardIdleConnectionsSeconds = discardIdleConnectionsSeconds;
    }
}

创建完成之后,还需要在配置文件中设置一下即可!

org:
  quartz:
    dataSource:
      qzDS:
        connectionProvider:
          class: com.mes.material.quartz.provider.DruidConnectionProvider

6、编写 Job 具体任务类

package com.mes.material.quartz.tfjob;

import com.mes.material.eam.domain.MaterialRequestVo;
import com.mes.material.eam.enums.InterfaceTypeEnum;
import com.mes.material.eam.service.StrategyService;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.redis.core.RedisTemplate;

import java.util.concurrent.TimeUnit;

//此标记用在实现Job的类上面,意思是不允许并发执行,按照我之前的理解是不允许调度框架在同一时刻调用Job类,后来经过测试发现并不是这样,
// 而是Job(任务)的执行时间[比如需要10秒]大于任务的时间间隔[Interval(5秒)],那么默认情况下,调度框架为了能让
//任务按照我们预定的时间间隔执行,会马上启用新的线程执行任务。否则的话会等待任务执行完毕以后再重新执行!(这样会导致任务的执行不是按照我们预先定义的时间间隔执行)
//测试代码,这是官方提供的例子。设定的时间间隔为3秒,但job执行时间是5秒,设置@DisallowConcurrentExecution以后程序会等任务执行完毕以后再去执行,
// 否则会在3秒时再启用新的线程执行

@DisallowConcurrentExecution
public class TfCommandJob implements Job {

    @Autowired
    private StrategyService strategyService;

    private static final Logger log = LoggerFactory.getLogger(TfCommandJob.class);

    private static final String lock_key = "material_from_eam_info";

    private static final String lock_value = "material_from_eam_info_zkaw";

    @Value("${schedule.expire}")
    private long timeOut;

    @Autowired
    private RedisTemplate redisTemplate;

    @Override
    public void execute(JobExecutionContext context) {
        try {
            //分布式锁
            boolean lock = false;
            try {
                //如果返回true,说明key不存在,获取到锁
                lock = redisTemplate.opsForValue().setIfAbsent(lock_key, lock_value);
                log.info("是否获取到锁:" + lock);
                if (lock) {
                    log.info("获取到锁,开启定时任务!");
                    //设置过期时间
                    redisTemplate.expire(lock_key, timeOut, TimeUnit.SECONDS);
                    //调用EAM接口,同步物资数据
                    log.info("调用EAM接口,同步物资数据");
                    String type = InterfaceTypeEnum.autoMaterial.getCode();
                    MaterialRequestVo materialRequestVo = new MaterialRequestVo();
                    materialRequestVo.setType(type);
                    strategyService.render(type).materialInfoMesToRoma(materialRequestVo);
                 } else {
                    log.info("其他系统正在执行此项任务");
                    return;
                }
            } catch (Exception e) {
                e.printStackTrace();
            } catch (Throwable throwable) {
                throw new RuntimeException("分布式锁执行发生异常" + throwable.getMessage(), throwable);
            }

        } catch (Exception e) {
            log.error("任务执行失败",e);
        }
    }
}

7、编写 Quartz 服务层接口

package com.mes.material.quartz.service;

import java.util.Map;

/**
 * @Author: 
 * @Description: 3.8、编写 Quartz 服务层接口
 * @Date Create in 14:14 2022/5/16

public interface IQuartzJobService {
    /**
     * 添加任务可以传参数
     * @param clazzName
     * @param jobName
     * @param groupName
     * @param cronExp

     */
    void addJob(String clazzName, String jobName, String groupName, String cronExp, Map param);

    /**
     * 暂停任务
     * @param jobName
     * @param groupName
     */
    void pauseJob(String jobName, String groupName);

    /**
     * 恢复任务
     * @param jobName
     * @param groupName
     */
    void resumeJob(String jobName, String groupName);

    /**
     * 立即运行一次定时任务
     * @param jobName
     * @param groupName
     */
    void runOnce(String jobName, String groupName);

    /**
     * 更新任务
     * @param jobName
     * @param groupName
     * @param cronExp
     * @param param
     */
    void updateJob(String jobName, String groupName, String cronExp, Map param);

    /**
     * 删除任务
     * @param jobName
     * @param groupName
     */
    void deleteJob(String jobName, String groupName);

    /**
     * 启动所有任务
     */
    void startAllJobs();

    /**
     * 暂停所有任务
     */
    void pauseAllJobs();

    /**
     * 恢复所有任务
     */
    void resumeAllJobs();

    /**
     * 关闭所有任务
     */
    void shutdownAllJobs();
}

8、编写 Quartz 服务层接口实现类

package com.mes.material.quartz.service.impl;

import org.quartz.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

9、编写 contoller 服务

先编写一个调用实体类

package com.mes.material.quartz.config;

import lombok.Data;

import java.io.Serializable;
import java.util.Map;

/**

@Data
public class QuartzConfigDTO implements Serializable {
    private static final long serialVersionUID = 1L;
    /**
     * 任务名称
     */
    private String jobName;

    /**
     * 任务所属组
     */
    private String groupName;

    /**
     * 任务执行类
     */
    private String jobClass;

    /**
     * 任务调度时间表达式
     */
    private String cronExpression;

    /**
     * 附加参数
     */
    private Map param;
}

web服务接口

@RestController

10、调用quartz

常量值

 11、注册监听器(选用)

  • 创建任务调度监听器
package com.mes.material.quartz.listener;

import org.quartz.*;

}
  • 创建任务触发监听器

     * 任务完成时触发
     * @param trigger
     * @param context
     * @param triggerInstructionCode
     */
    @Override
    public void triggerComplete(Trigger trigger, JobExecutionContext context, Trigger.CompletedExecutionInstruction triggerInstructionCode) {
        System.out.println("myTriggerListener.triggerComplete()");
    }
}
  • 创建任务执行监听器
package com.mes.material.quartz.listener;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.listeners.JobListenerSupport;
import org.springframework.stereotype.Component;

/**
 * @Author: 
 * @Description: 任务执行监听器
 * @Date Create in 14:49 2022/5/16
 * @Modified By:
 */

@Component
public class SimpleJobListener extends JobListenerSupport {


    /**
     * job监听器名称
     * @return
     */
    @Override
    public String getName() {
        return "mySimpleJobListener";
    }

    /**
     * 任务被调度前
     * @param context
     */
    @Override
    public void jobToBeExecuted(JobExecutionContext context) {
        System.out.println("simpleJobListener监听器,准备执行:"+context.getJobDetail().getKey());
    }

    /**
     * 任务调度被拒了
     * @param context
     */
    @Override
    public void jobExecutionVetoed(JobExecutionContext context) {
        System.out.println("simpleJobListener监听器,取消执行:"+context.getJobDetail().getKey());
    }

    /**
     * 任务被调度后
     * @param context
     * @param jobException
     */
    @Override
    public void jobWasExecuted(JobExecutionContext context, JobExecutionException jobException) {
        System.out.println("simpleJobListener监听器,执行结束:"+context.getJobDetail().getKey());
    }
}
  • 最后,将监听器注册到Scheduler
@Autowired
private SimpleSchedulerListener simpleSchedulerListener;
 
@Autowired
private SimpleJobListener simpleJobListener;
 
@Autowired
private SimpleTriggerListener simpleTriggerListener;
 
@Bean(name = "scheduler")
public Scheduler scheduler() throws IOException, SchedulerException {
    Scheduler scheduler = schedulerFactoryBean().getScheduler();
    //全局添加监听器
    //添加SchedulerListener监听器
    scheduler.getListenerManager().addSchedulerListener(simpleSchedulerListener);
 
    // 添加JobListener, 支持带条件匹配监听器
    scheduler.getListenerManager().addJobListener(simpleJobListener, KeyMatcher.keyEquals(JobKey.jobKey("myJob", "myGroup")));
 
    // 添加triggerListener,设置全局监听
    scheduler.getListenerManager().addTriggerListener(simpleTriggerListener, EverythingMatcher.allTriggers());
    return scheduler;
}

本文主要围绕springboot + quartz + postgresql实现持久化分布式调度进行介绍,所有的代码功能,都测试过。
