springboot使用quartz集羣定時任務

簡介

Quartz是一個完全由java編寫的開源作業調度框架。不要讓作業調度這個術語嚇着你。儘管Quartz框架整合了許多額外功能， 但就其簡易形式看，你會發現它易用得簡直讓人受不了！。簡單地創建一個實現org.quartz.Job接口的java類。Job接口包含唯一的方法：

public void execute(JobExecutionContext context) throws JobExecutionException;

在你的Job接口實現類裏面，添加一些邏輯到execute()方法。一旦你配置好Job實現類並設定好調度時間表，Quartz將密切注意剩餘時間。當調度程序確定該是通知你的作業的時候，Quartz框架將調用你Job實現類（作業類）上的execute()方法並允許做它該做的事情。無需報告任何東西給調度器或調用任何特定的東西。僅僅執行任務和結束任務即可。如果配置你的作業在隨後再次被調用，Quartz框架將在恰當的時間再次調用它。

單機部署問題

單機模式下的定時任務調用很簡單，有很多可實現的方案，這裏不多說了，例如spring schedule，java timer等。

這裏說一下集羣部署的情況下，定時任務的使用。這種情況下，quartz是一個比較好的選擇。簡單，穩定。

想象一下，現在有 A ， B ， C 3 臺機器同時作爲集羣服務器對外統一提供 SERVICE ：

A ， B ， C 3 臺機器上各有一個 QUARTZ Job，它們會按照即定的 SCHEDULE 自動執行各自的任務。

先不說實現什麼功能，這樣的架構有點像多線程。由於三臺SERVER 裏都有 QUARTZ ，因此會存在重複處理 TASK 的現象。

一般外面的解決方案是隻在一臺 服務器上裝 QUARTZ ，其它兩臺不裝，這樣的話其實就是單機了，quartz存在單點問題，一旦裝有quartz的服務器宕了。服務就無法提供了。

當然還有其他一些解決方案，無非就是改 QUARTZ JOB 的代碼了，這對程序開發人員來說比較痛苦；

而quartz本身提供了很好的集羣方案。下面我們來說一下在spring boot下的集成：

quartz集羣需要數據庫的支持（JobStore TX或者JobStoreCMT），從本質上來說，是使集羣上的每一個節點通過共享同一個數據庫來工作的

1 準備quartz基本環境

到quartz官網下載最新的包：http://www.quartz-scheduler.org/downloads/

解壓後，可以看到結構目錄。在\docs\dbTables下選擇合適你數據庫的SQL執行文件，創建quartz集羣需要的表（共11張表）

找到自己使用的數據庫腳本文件執行

數據庫中對應表，注意：在windows環境下，mysql表名不確認大小寫，linux下區分大小寫

2 集成springboot（這裏是1.5.3版本）

2.1引入依賴jar包

        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.3</version>
        </dependency>

2.2 quartz配置

#quartz集羣配置  
# ===========================================================================    
# Configure Main Scheduler Properties 調度器屬性    
# ===========================================================================  
#調度標識名 集羣中每一個實例都必須使用相同的名稱    
org.quartz.scheduler.instanceName=DefaultQuartzScheduler  
#ID設置爲自動獲取 每一個必須不同  
org.quartz.scheduler.instanceid=AUTO    
#============================================================================  
# Configure ThreadPool    
#============================================================================  
#線程池的實現類（一般使用SimpleThreadPool即可滿足幾乎所有用戶的需求）  
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool  
#指定線程數，至少爲1（無默認值）(一般設置爲1-100直接的整數合適)  
org.quartz.threadPool.threadCount = 25  
#設置線程的優先級（最大爲java.lang.Thread.MAX_PRIORITY 10，最小爲Thread.MIN_PRIORITY 1，默認爲5）   
org.quartz.threadPool.threadPriority = 5  
#============================================================================  
# Configure JobStore    
#============================================================================  
# 信息保存時間 默認值60秒   
org.quartz.jobStore.misfireThreshold = 60000  
#數據保存方式爲數據庫持久化  
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX  
#數據庫代理類，一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以滿足大部分數據庫  
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate  
#JobDataMaps是否都爲String類型  
org.quartz.jobStore.useProperties = false  
#數據庫別名 隨便取  
org.quartz.jobStore.dataSource = myDS  
#表的前綴，默認QRTZ_  
org.quartz.jobStore.tablePrefix = QRTZ_  
#是否加入集羣  
org.quartz.jobStore.isClustered = true  
#調度實例失效的檢查時間間隔  
org.quartz.jobStore.clusterCheckinInterval = 20000  
#============================================================================  
# Configure Datasources    
#============================================================================  
#數據庫引擎  
org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver  
#數據庫連接  
org.quartz.dataSource.myDS.URL = jdbc:mysql://172.30.12.14:7001/rbl_test?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowMultiQueries=true  
#數據庫用戶  
org.quartz.dataSource.myDS.user = root  
#數據庫密碼  
org.quartz.dataSource.myDS.password = 123456  
#允許最大連接  
org.quartz.dataSource.myDS.maxConnections = 5  
#驗證查詢sql,可以不設置  
org.quartz.dataSource.myDS.validationQuery=select 0 from dual 
注：如果嫌需要額外配置quart數據源很煩，也可以共用你項目配置的數據庫鏈接，這樣每次更換數據庫連接，就不需要額外在修改。

2.3 springboot configuration 配置

直接使用springboot注入的的datasource的內容配置quartz的數據庫連接

quartz屬性配置可以讀取配置文件讀取，我這裏沒在配置文件讀取，直接寫在代碼裏測試的，意見新建一個配置文件裏面寫quartz的配置內容，然後通過springboot注入屬性進來。

package com.kerry.config;


import java.io.IOException;
import java.util.Properties;

import javax.sql.DataSource;

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;


/**

 */
@Configuration
//@ConditionalOnProperty(prefix = "qybd", name = "quartz-open", havingValue = "true")
public class QuartzConfig{
    
    @Autowired
    DataSource dataSource;
    
    @Bean  
    public SchedulerFactoryBean schedulerFactoryBean(QuartzJobFactory myJobFactory) throws Exception {  
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();  
        schedulerFactoryBean.setDataSource(dataSource);  
        //使job實例支持spring 容器管理
        schedulerFactoryBean.setOverwriteExistingJobs(true);  
        schedulerFactoryBean.setJobFactory(myJobFactory);  
        schedulerFactoryBean.setQuartzProperties(quartzProperties());  
        // 延遲10s啓動quartz  
        schedulerFactoryBean.setStartupDelay(10);  
  
        return schedulerFactoryBean;  
    }
    
    
    
    @Bean
    public Scheduler scheduler(SchedulerFactoryBean schedulerFactoryBean) throws IOException, SchedulerException {
//      SchedulerFactory schedulerFactory = new StdSchedulerFactory(quartzProperties());
//      Scheduler scheduler = schedulerFactory.getScheduler();
//      scheduler.start();//初始化bean並啓動scheduler
         Scheduler scheduler = schedulerFactoryBean.getScheduler();  
         scheduler.start();
        return scheduler;
    }
    
    
    
    
    
    /**
     * 設置quartz屬性
     */
    public Properties quartzProperties() throws IOException {
        Properties prop = new Properties();
        prop.put("quartz.scheduler.instanceName", "ServerScheduler");
        prop.put("org.quartz.scheduler.instanceId", "AUTO");
        prop.put("org.quartz.scheduler.skipUpdateCheck", "true");
        prop.put("org.quartz.scheduler.instanceId", "NON_CLUSTERED");
        prop.put("org.quartz.scheduler.jobFactory.class", "org.quartz.simpl.SimpleJobFactory");
        prop.put("org.quartz.jobStore.class", "org.quartz.impl.jdbcjobstore.JobStoreTX");
        prop.put("org.quartz.jobStore.driverDelegateClass", "org.quartz.impl.jdbcjobstore.StdJDBCDelegate");
        prop.put("org.quartz.jobStore.dataSource", "quartzDataSource");
        prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");
        prop.put("org.quartz.jobStore.isClustered", "true");
        prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
        prop.put("org.quartz.threadPool.threadCount", "5");

//      prop.put("org.quartz.dataSource.quartzDataSource.driver", druidProperties.getDriverClassName());
//      prop.put("org.quartz.dataSource.quartzDataSource.URL", druidProperties.getUrl());
//      prop.put("org.quartz.dataSource.quartzDataSource.user", druidProperties.getUsername());
//      prop.put("org.quartz.dataSource.quartzDataSource.password", druidProperties.getPassword());
//      prop.put("org.quartz.dataSource.quartzDataSource.maxConnections", druidProperties.getMaxActive());
        return prop;
    }
    
}

注意上面的schedulerFactoryBean.setJobFactory(myJobFactory); //這個myJobFactory是自定義配置的一個類，如果這裏不配置這個jobFactory，下面的那個CtripScenicTask會爲空，獲取不了注入對象

@Component
public class CtripScenicJob implements Job{
    
    private Logger logger = LoggerFactory.getLogger(CtripScenicJob.class);

    @Autowired
    private CtripScenicTask ctripScenicTask; 

這個類主要解決spring管理的Quartz job裏面注入不了其他bean

package com.kerry.config;

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 {
    
    //這個對象Spring會幫我們自動注入進來,也屬於Spring技術範疇.
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;
    
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        //調用父類的方法
        Object jobInstance = super.createJobInstance(bundle);
        //進行注入,這屬於Spring的技術,不清楚的可以查看Spring的API.
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }

}

    void delete(String jobName, String jobGroup);
    
    void pause(String jobName, String jobGroup);

任務實現類實現job接口，重寫execute方法

package com.kerry.modular.biz.task.quartz;


import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.kerry.modular.biz.task.schedule.CtripScenicTask;

@Component
public class CtripScenicJob implements Job{
    
    private Logger logger = LoggerFactory.getLogger(CtripScenicJob.class);

    @Autowired
    private CtripScenicTask ctripScenicTask;
    
    @Override
    public void execute(JobExecutionContext context)
            throws JobExecutionException {
        logger.info("JobName: {}", context.getJobDetail().getKey().getName());
        ctripScenicTask.loadComment();
    }
    
    

}

此時可以通過調用TaskManageController時間動態控制定時任務

3 測試，啓動springboot項目

輸入添加任務的url：

http://localhost:8080/qy/api/task/save?jobName=com.stylefeng.guns.modular.biz.task.quartz.CtripHotelJob&jobGroup=group1&jobDescription=job描述&cronExpression=0/10 * * * * ?

jobName爲job類的包名類名，jobGroup該任務所屬組，jobDescription 描述，cronExpression ：core表達式

上面的請求會添加一個定時任務，每10秒執行一次 CtripHotelJob裏面的execute方法。

保存的定時任務會在quartz相關表裏保存數據

如：
