SpringBoot+Quartz+数据库存储

目录
1、Spring整合Quartz
2、读取数据库来开启定时任务（案例）

Spring整合Quartz

a、quartz调度框架是有内置表的
进入quartz的官网 link，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”
table_mysql.sql
table_mysql_innodb.sql
上述两者所有的数据库引擎不一样
比如我的是mysql数据库，它里面有11张表，这些表是我们后面操作Quartz需要的

b、导入pom依赖

<dependency>
	<groupId>org.quartz-scheduler</groupId>
	<artifactId>quartz-jobs</artifactId>
	<version>2.2.1</version>
   </dependency>
   <dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-quartz</artifactId>
   </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>

   更换成Druid连接池

   A、 引入依赖

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

   B、 导入DruidConnectionProvider.java

C、修改quartz.properties配置

#配置数据库源
org.quartz.dataSource.qzDS.connectionProvider.class:
com.javaxl.项目名.util.DruidConnectionProvider

c、在项目中添加quartz.properties文件(这样就不会加载自带的properties文件)
此文件的内容主要分为：scheduler，ThreadPool，JobStore，plugin，Datasources等部分，
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

d、自定义MyJobFactory，解决spring不能在quartz中注入bean的问题
e、创建调度器schedule，交给spring进行管理
f、创建自定义任务
g、更新quartz中的任务
h、自定义任务表与quartz内置表的区分

要搞清楚一个问题：从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。

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,                                -- ID
  cron 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,                                -- ID
  name 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)
);

Quartz默认的连接池是c3p0，如果你的连接池不同需要直接替换它的配置文件，比如我用的连接池是druid，就需要自己改配置（如果就用c3p0就不需要改）

然后在后面把这个文件配会丢入我们的配置文件中

需要配置我们的JobFactory，因为我们在项目开发中是需要在Job中操作数据库的，那么当然需要把它交给spring管理，但是quartz本身是不支持的，所以我们需要修改它的底层代码，让我们的Job类能被spring所管理

MyJobFactory

package com.cgl.quartz02.util;

import lombok.extern.slf4j.Slf4j;
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
@Slf4j
public class MyJobFactory extends AdaptableJobFactory {

    //这个对象Spring会帮我们自动注入进来
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    //重写创建Job任务的实例方法
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        //通过以下方式，解决Job任务无法使用Spring中的Bean问题
        autowireCapableBeanFactory.autowireBean(jobInstance);
        return super.createJobInstance(bundle);
    }
}

然后把刚刚写的配置全部丢进我们的配置类中

QuartzConfiguration

package com.cgl.quartz02.config;

import com.cgl.quartz02.util.MyJobFactory;
import org.quartz.Scheduler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

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

@Configuration
public class QuartzConfiguration {

    @Autowired
    private MyJobFactory myJobFactory;

    //创建调度器工厂
    @Bean
        public SchedulerFactoryBean schedulerFactoryBean(){
            //1.创建SchedulerFactoryBean
            //2.加载自定义的quartz.properties配置文件
            //3.设置MyJobFactory

            SchedulerFactoryBean factoryBean=new SchedulerFactoryBean();
            try {
                factoryBean.setQuartzProperties(quartzProperties());
                factoryBean.setJobFactory(myJobFactory);
                return factoryBean;
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
    }

    @Bean
    public Properties quartzProperties() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean=new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    @Bean(name="scheduler")
    public Scheduler scheduler(){
        return schedulerFactoryBean().getScheduler();
    }
}

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;

读取数据库来开启定时任务（案例）

那么我们还需要自己创建两张表，通过这两张表和Quartz的内置表来管理动态的定时任务,表里面的数据我们测试用的数据

t_schedule_trigger，管理具体的任务，
id：标识列
cron：表达式
status（0关闭，1开启）是否开启
job_name：job的name
job_group：job的group

t_schedule_trigger——param,管理传递的参数

MyJob（更改定时任务状态）

当禁用该触发器时，那么程序只会执行spring自带的定时任务，每10s执行一次查询，所以打印语句如上。

package com.cgl.quartz02.quartz;

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 {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("MyJob是一个空的任务计划,时间："+new Date().toLocaleString());
    }
}

MyJob1（定时任务中携带参数）

程序执行spring自带的定时任务，每10s执行一次查询，查询t_schedule_trigger表，调度器表中有两个调度器，都是每5s执行一次，其中一个调度器是需要携带参数的，携带的参数在t_schedule_trigger_param表中，所以一开始调度器启动的时候需要查询t_schedule_trigger_param表数据，最终打印语句如上。

package com.cgl.quartz02.quartz;

import com.cgl.quartz02.service.ScheduleTriggerParamService;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

/**

 */
@Component
@Slf4j
public class MyJob1 implements Job {

    @Autowired
    private ScheduleTriggerParamService scheduleTriggerParamService;

    @Override
    public 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());
    }
}

MyJob2（更改定时任务规则）

程序执行spring自带的定时任务，每10s执行一次查询，查询t_schedule_trigger表，将任务3的表达式由0/3 * * * * ?改成0/20 * * * * ?，最终结果如上

package com.cgl.quartz02.quartz;

import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @author caoguangli

@Component
@Slf4j
public class MyJob2 implements Job {
    @Override
    public 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"));
    }
}
