简介

Quartz是一个完全由java编写的开源作业调度框架。不要让作业调度这个术语吓着你。尽管Quartz框架整合了许多额外功能，但就其简易形式看，你会发现它易用得简直让人受不了！。简单地创建一个实现org.quartz.Job接口的java类。Job接口包含唯一的方法：

public void execute(JobExecutionContext context) throws JobExecutionException;

在你的Job接口实现类里面，添加一些逻辑到execute()方法。一旦你配置好Job实现类并设定好调度时间表，Quartz将密切注意剩余时间。当调度程序确定该是通知你的作业的时候，Quartz框架将调用你Job实现类（作业类）上的execute()方法并允许做它该做的事情。无需报告任何东西给调度器或调用任何特定的东西。仅仅执行任务和结束任务即可。如果配置你的作业在随后再次被调用，Quartz框架将在恰当的时间再次调用它。

单机部署问题

单机模式下的定时任务调用很简单，有很多可实现的方案，这里不多说了，例如spring schedule，java timer等。

这里说一下集群部署的情况下，定时任务的使用。这种情况下，quartz是一个比较好的选择。简单，稳定。

想象一下，现在有 A ， B ， C 3 台机器同时作为集群服务器对外统一提供 SERVICE ：

A ， B ， C 3 台机器上各有一个 QUARTZ Job，它们会按照即定的 SCHEDULE 自动执行各自的任务。

先不说实现什么功能，这样的架构有点像多线程。由于三台SERVER 里都有 QUARTZ ，因此会存在重复处理 TASK 的现象。

一般外面的解决方案是只在一台服务器上装 QUARTZ ，其它两台不装，这样的话其实就是单机了，quartz存在单点问题，一旦装有quartz的服务器宕了。服务就无法提供了。

当然还有其他一些解决方案，无非就是改 QUARTZ JOB 的代码了，这对程序开发人员来说比较痛苦；

而quartz本身提供了很好的集群方案。下面我们来说一下在spring boot下的集成：

quartz集群需要数据库的支持（JobStore TX或者JobStoreCMT），从本质上来说，是使集群上的每一个节点通过共享同一个数据库来工作的

1 准备quartz基本环境

到quartz官网下载最新的包：http://www.quartz-scheduler.org/downloads/

解压后，可以看到结构目录。在\docs\dbTables下选择合适你数据库的SQL执行文件，创建quartz集群需要的表（共11张表）

找到自己使用的数据库脚本文件执行

数据库中对应表，注意：在windows环境下，mysql表名不确认大小写，linux下区分大小写

2 集成springboot（这里是1.5.3版本）

2.1引入依赖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集群配置
# ===========================================================================
# Configure Main Scheduler Properties 调度器属性
# ===========================================================================
#调度标识名集群中每一个实例都必须使用相同的名称
org.quartz.scheduler.instanceName=DefaultQuartzScheduler
#ID设置为自动获取每一个必须不同
org.quartz.scheduler.instanceid=AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
#线程池的实现类（一般使用SimpleThreadPool即可满足几乎所有用户的需求）
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
#指定线程数，至少为1（无默认值）(一般设置为1-100直接的整数合适)
org.quartz.threadPool.threadCount = 25
#设置线程的优先级（最大为java.lang.Thread.MAX_PRIORITY 10，最小为Thread.MIN_PRIORITY 1，默认为5）
org.quartz.threadPool.threadPriority = 5
#============================================================================
# Configure JobStore
#============================================================================
# 信息保存时间默认值60秒
org.quartz.jobStore.misfireThreshold = 60000
#数据保存方式为数据库持久化
org.quartz.jobStore.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
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#JobDataMaps是否都为String类型
org.quartz.jobStore.useProperties = false
#数据库别名随便取
org.quartz.jobStore.dataSource = myDS
#表的前缀，默认QRTZ_
org.quartz.jobStore.tablePrefix = QRTZ_
#是否加入集群
org.quartz.jobStore.isClustered = true
#调度实例失效的检查时间间隔
org.quartz.jobStore.clusterCheckinInterval = 20000
#============================================================================
# Configure Datasources
#============================================================================
#数据库引擎
org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver
#数据库连接
org.quartz.dataSource.myDS.URL = jdbc:mysql://172.30.12.14:7001/rbl_test?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowMultiQueries=true
#数据库用户
org.quartz.dataSource.myDS.user = root
#数据库密码
org.quartz.dataSource.myDS.password = 123456
#允许最大连接
org.quartz.dataSource.myDS.maxConnections = 5
#验证查询sql,可以不设置
org.quartz.dataSource.myDS.validationQuery=select 0 from dual

注：如果嫌需要额外配置quart数据源很烦，也可以共用你项目配置的数据库链接，这样每次更换数据库连接，就不需要额外在修改。

2.3 springboot configuration 配置

直接使用springboot注入的的datasource的内容配置quartz的数据库连接

quartz属性配置可以读取配置文件读取，我这里没在配置文件读取，直接写在代码里测试的，意见新建一个配置文件里面写quartz的配置内容，然后通过springboot注入属性进来。

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.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;


/**
 * 分布式定时任务管理配置
 * @author kerry
 * @date 2018-05-09 11:36:21
 */
@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实例支持spring 容器管理
        schedulerFactoryBean.setOverwriteExistingJobs(true);  
        schedulerFactoryBean.setJobFactory(myJobFactory);  
        schedulerFactoryBean.setQuartzProperties(quartzProperties());  
        // 延迟10s启动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并启动scheduler
		 Scheduler scheduler = schedulerFactoryBean.getScheduler();  
		 scheduler.start();
		return scheduler;
	}
	
	
	
	
	
	/**
	 * 设置quartz属性
	 */
	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); //这个myJobFactory是自定义配置的一个类，如果这里不配置这个jobFactory，下面的那个CtripScenicTask会为空，获取不了注入对象

@Component
public class CtripScenicJob implements Job{

private Logger logger = LoggerFactory.getLogger(CtripScenicJob.class);

@Autowired
private CtripScenicTask ctripScenicTask;

这个类主要解决spring管理的Quartz job里面注入不了其他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 {
	
	//这个对象Spring会帮我们自动注入进来,也属于Spring技术范畴.
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;
    
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        //调用父类的方法
        Object jobInstance = super.createJobInstance(bundle);
        //进行注入,这属于Spring的技术,不清楚的可以查看Spring的API.
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }

}

2.4 动态配置管理quartz

接口类

package com.kerry.modular.biz.service;

import java.util.List;





import org.quartz.SchedulerException;

import com.kerry.modular.biz.model.TaskInfo;

public interface TaskService {

	List<TaskInfo> list();
	
	void addJob(TaskInfo info);
	
	void edit(TaskInfo info);
	
	void delete(String jobName, String jobGroup);
	
	void pause(String jobName, String jobGroup);
	
	void resume(String jobName, String jobGroup);
	
	boolean checkExists(String jobName, String jobGroup)throws SchedulerException;
}

任务实现类实现job接口，重写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();
	}
	
	

}

此时可以通过调用TaskManageController时间动态控制定时任务

3 测试，启动springboot项目

输入添加任务的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为job类的包名类名，jobGroup该任务所属组，jobDescription 描述，cronExpression ：core表达式

上面的请求会添加一个定时任务，每10秒执行一次 CtripHotelJob里面的execute方法。

保存的定时任务会在quartz相关表里保存数据

如：

springboot使用quartz集群定时任务
