Spring整合Quartz

quartz调度框架是有内置表的
进入quartz的官网 http://www.quartz-scheduler.org/ ，点击Downloads，
下载后在目录\docs\dbTables下有常用数据库创建quartz表的脚本，例如：“tables_mysql.sql”

新建项目:

导入pom依赖

<dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz-jobs</artifactId><version>2.2.1</version>
</dependency>

<!--quartz需要使用C3P0连接池将数据持久化到数据库--><!--Quartz各版本数据库连接池技术更新情况--><!--Quartz 2.0 以前 DBCP--><!--Quartz 2.0 以后 C3P0（包含2.0）--><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency>

这里我用的是Druid连接池,所以需要更换成Druid连接池
引入依赖

   <dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency>

还需要的依赖:

jdbc.password=123
jdbc.initialSize=10

在项目中添加quartz.properties文件(这样就不会加载自带的properties文件)
覆盖properties文件的目的是覆盖默认的数据源，更换为druid的数据配置

MyJobFactory

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;

}

QuartzConfiguration.java（quartz调度框架与spring框架整合的配置类，主要是要将org.quartz.Scheduler交给spring进行管理）

package com.zh.quartz02.config;import com.zh.quartz02.util.MyJobFactory;
import org.quartz.Scheduler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.PropertiesFactoryBean;

}

自定义的业务表
-- 注意：job_name存放的任务类的全路径，在quartz中通过jobName和jobGroup来确定trigger的唯一性，所以这两列为联合唯一索引
create table t_schedule_trigger
(id int primary key auto_increment,                                -- IDcron varchar(200) not null,                                       -- 时间表达式status char(1) not null,                                          -- 使用状态 0：禁用   1：启用job_name varchar(200) not null,                                   -- 任务名称job_group varchar(200) not null,                                  -- 任务分组  unique index(job_name,job_group)
);-- 额外添加到任务中的参数
create table t_schedule_trigger_param
(param_id int primary key auto_increment,                                -- IDname varchar(200) not null,                                             -- 参数名value varchar(512),                                                     -- 参数值schedule_trigger_id int not null,                                       -- 外键：引用t_schedule_trigger(id)foreign key(schedule_trigger_id) references t_schedule_trigger(id)
);

案例中需要观察表数据变化的表

-- 自定义的业务表
SELECT * FROM t_schedule_trigger;
SELECT * FROM t_schedule_trigger_param;-- quartz调度框架自带的表
SELECT * FROM qrtz_scheduler_state;
SELECT * FROM qrtz_cron_triggers;
SELECT * FROM qrtz_simple_triggers
SELECT * FROM qrtz_triggers;
SELECT * FROM qrtz_job_details;

逆向生成:

ScheduleTriggerMapper.java

/*** 查询触发器中包含的所有任务* @return*/List<ScheduleTrigger> queryScheduleTriggerLst();

ScheduleTriggerParamMapper.java

/*** 查询出当前任务类对应所需的参数* @param triggerId* @return*/List<ScheduleTriggerParam> queryScheduleParamLst(Integer triggerId);

ScheduleTriggerMapper.xml

<select id="queryScheduleTriggerLst" resultType="com.zh.quartz02.model.ScheduleTrigger">select <include refid="Base_Column_List"/>from t_schedule_trigger</select>

ScheduleTriggerParamMapper.xml

<select id="queryScheduleParamLst" resultType="com.zh.quartz02.model.ScheduleTriggerParam">select <include refid="Base_Column_List"/>from t_schedule_trigger_param where schedule_trigger_id=#{triggerId}</select>

spring自带定时任务作业类ScheduleTriggerServiceImpl.java

package com.zh.quartz02.service.impl;import com.zh.quartz02.mapper.ScheduleTriggerMapper;
import com.zh.quartz02.mapper.ScheduleTriggerParamMapper;
import com.zh.quartz02.model.ScheduleTrigger;
import com.zh.quartz02.model.ScheduleTriggerParam;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;import java.util.List;@Service
public class ScheduleTriggerParamServiceImpl {@Autowiredprivate ScheduleTriggerMapper scheduleTriggerMapper;@Autowiredprivate ScheduleTriggerParamMapper scheduleTriggerParamMapper;@Autowiredprivate Scheduler scheduler;@Scheduled(cron = "0/10 * * * * ?")public void refreshScheduler(){try {List<ScheduleTrigger> scheduleTriggers =scheduleTriggerMapper.queryScheduleTriggerLst();if(null!=scheduleTriggers){for (ScheduleTrigger scheduleTrigger : scheduleTriggers) {String cron = scheduleTrigger.getCron();  //表达式String jobName = scheduleTrigger.getJob_name(); //任务名称String jobGroup = scheduleTrigger.getJob_group(); //任务分组String status = scheduleTrigger.getStatus();  //任务状态//JobName+JobGroup=Primary Key//根据jobName和jobGroup生成TriggerKeyTriggerKey triggerKey =TriggerKey.triggerKey(jobName, jobGroup);//根据TriggerKey到Scheduler调度器中获取触发器CronTrigger cronTrigger = (CronTrigger)scheduler.getTrigger(triggerKey);if(null==cronTrigger){if(status.equals("0"))continue;System.out.println("创建调度器");//创建任务详情JobDetail jobDetail=JobBuilder.newJob((Class<? extends Job>) Class.forName(jobName)).withIdentity(jobName,jobGroup).build();//往Job任务中传递参数JobDataMap jobDataMap = jobDetail.getJobDataMap();List<ScheduleTriggerParam> params =scheduleTriggerParamMapper.queryScheduleParamLst(scheduleTrigger.getId());for (ScheduleTriggerParam param : params) {jobDataMap.put(param.getName(),param.getValue());}//创建表达式调度器CronScheduleBuilder cronSchedule =CronScheduleBuilder.cronSchedule(cron);//创建TriggercronTrigger=TriggerBuilder.newTrigger().withIdentity(jobName,jobGroup).withSchedule(cronSchedule).build();//将jobDetail和Trigger注入到scheduler调度器中scheduler.scheduleJob(jobDetail,cronTrigger);}else{//System.out.println("Quartz 调度任务中已存在该任务");if(status.equals("0")){JobKey jobKey = JobKey.jobKey(jobName, jobGroup);scheduler.deleteJob(jobKey);continue;}//调度器中的表达式String cronExpression =cronTrigger.getCronExpression();if(!cron.equals(cronExpression)){//创建表达式调度器CronScheduleBuilder cronSchedule =CronScheduleBuilder.cronSchedule(cron);//重构cronTrigger=cronTrigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(cronSchedule).build();//刷新调度器scheduler.rescheduleJob(triggerKey,cronTrigger);}}}}} catch (Exception e) {e.printStackTrace();}}
}

数据库读取任务信息动态生成定时任务，和把quartz持久化到数据库是没有关系的。前者是我们自己定义的业务表，而后者是quartz使用自己的表来存储信息。持久化到数据库后，就算服务器重启或是多个quartz节点也没关系，因为他们共享数据库中的任务信息。

读取数据库中表达式启动定时任务

MyJob.java

package com.zh.quartz02.job;import lombok.extern.slf4j.Slf4j;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.stereotype.Component;import java.util.Date;@Component
@Slf4j
public class MyJob implements Job {@Overridepublic void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {System.out.println("MyJob是一个空的任务计划,时间："+new Date().toLocaleString());}
}

在Quartz02Application里加上注解

Spring自带定时任务每10s执行一次，查询自定义触发器表，获取到具体的作业类及任务表达式，quartz的任务为每5s执行一次，所以打印:

package com.zh.quartz02.job;import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.stereotype.Component;import java.util.Date;@Component
@Slf4j
public class MyJob1 implements Job {@Overridepublic void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {JobDetail jobDetail =jobExecutionContext.getJobDetail();JobDataMap jobDataMap = jobDetail.getJobDataMap();System.out.println(new Date().toLocaleString()+"-->携带参数个数:"+jobDataMap.size());}
}

package com.zh.quartz02.job;import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.stereotype.Component;import java.util.Date;@Component
@Slf4j
public class MyJob2 implements Job {@Overridepublic void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {JobDetail jobDetail =jobExecutionContext.getJobDetail();JobDataMap jobDataMap = jobDetail.getJobDataMap();System.out.println(new Date().toLocaleString()+"-->MyJob2参数传递name="+jobDataMap.get("name")+",score="+jobDataMap.get("score"));}
}
