1、Spring整合Quartz

a、quartz调度框架是有内置表的，使用quartz就必须使用它的内置表，下载内置表在以下官网，自行下载
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”，我使用的MySQL，根据自己的版本来定

因为我创建的项目是springboot项目，在创建的时候quartz的pom依赖已经导入进来，但是它还缺少另外关于quartz的jar包，

<dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz-jobs</artifactId><version>2.2.1</version></dependency> quartz默认使用的是C3P0连接池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 DBCPQuartz 2.0 以后 C3P0（包含2.0）

我这里使用的Druid连接池，所以导入它的jar包

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

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

# #============================================================================ # Configure Main Scheduler Properties 调度器属性 #============================================================================ org.quartz.scheduler.instanceName: DefaultQuartzScheduler org.quartz.scheduler.instanceId = AUTO org.quartz.scheduler.rmi.export: false org.quartz.scheduler.rmi.proxy: false org.quartz.scheduler.wrapJobExecutionInUserTransaction: false org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount= 10 org.quartz.threadPool.threadPriority: 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true org.quartz.jobStore.misfireThreshold: 60000 #============================================================================ # Configure JobStore #============================================================================ #存储方式使用JobStoreTX，也就是数据库 org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass:org.quartz.impl.jdbcjobstore.StdJDBCDelegate #使用自己的配置文件 org.quartz.jobStore.useProperties:true #数据库中quartz表的表名前缀 org.quartz.jobStore.tablePrefix:qrtz_ org.quartz.jobStore.dataSource:qzDS #是否使用集群（如果项目只部署到 一台服务器，就不用了） org.quartz.jobStore.isClustered = true #============================================================================ # Configure Datasources #============================================================================ #配置数据库源（org.quartz.dataSource.qzDS.maxConnections: c3p0配置的是有s的，druid数据源没有s） org.quartz.dataSource.qzDS.connectionProvider.class:com.javaxl.quartz02.utils.DruidConnectionProvider org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/mybatis_ssm?useUnicode=true&characterEncoding=utf8 org.quartz.dataSource.qzDS.user: mybatis_ssm org.quartz.dataSource.qzDS.password: xiaoli org.quartz.dataSource.qzDS.maxConnection: 10

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。

MyJobFactory

package com.tzp.quartz02.utils;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@Autowiredprivate AutowireCapableBeanFactory autowireCapableBeanFactory;//重写创建Job任务的实例方法@Overrideprotected 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);} }

使用Druid它的数据源

DruidConnectionProvider

package com.tzp.quartz02.utils;import com.alibaba.druid.pool.DruidDataSource; import org.quartz.SchedulerException; import org.quartz.utils.ConnectionProvider;import java.sql.Connection; import java.sql.SQLException;/* #============================================================================ #

建立配置类 QuartzConfiguration（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）
1、将调度器交给spring进行管理，调度器就是对quartz.properties进行建模读取 ，生产的调度工厂，然后调度工厂生产出来的调度器

package com.tzp.quartz02.config;import com.tzp.quartz02.utils.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 {@Autowiredprivate MyJobFactory myJobFactory;//创建调度器工厂@Beanpublic SchedulerFactoryBean schedulerFactoryBean(){//1.创建SchedulerFactoryBean//2.加载自定义的quartz.properties配置文件//3.设置MyJobFactorySchedulerFactoryBean factoryBean=new SchedulerFactoryBean();try {factoryBean.setQuartzProperties(quartzProperties());factoryBean.setJobFactory(myJobFactory);return factoryBean;} catch (IOException e) {throw new RuntimeException(e);}}@Beanpublic 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;

jdbc.properties

给启动类添加注解

package com.tzp.quartz02;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.transaction.annotation.EnableTransactionManagement;@MapperScan("com.tzp.quartz02.mapper") @EnableTransactionManagement @EnableScheduling @SpringBootApplication public class Quartz02Application {public static void main(String[] args) {SpringApplication.run(Quartz02Application.class, args);}}

读取数据库中表达式启动定时任务

（每5s执行）
另外就是还需要自己创建两个表，一是调度表（触发器），二是调度表的参数表
调度表里就是所有的定时任务，参数表呢就是如果定时任务所要传递的参数
需要请自行提取
链接：https://pan.baidu.com/s/1fbF1jmZVHqZsjhTO7jiCRA
提取码：83j2

然后用mybatis逆向生成这两张表的实体类和mapper

ScheduleTriggerMapper
这个方法是查询出所有定时任务

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

ScheduleTriggerParamMapper
查询出当前任务类所需的参数

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

这是我的3个job类

数据库表t_schedule_trigger配置

MyJob1

package com.tzp.quartz02.quaertz;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 MyJob1 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());} }

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，所以打印如上

更改定时任务状态
更改数据库调度器表t_schedule_trigger的state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。

定时任务中携带参数
t_schedule_trigger

t_schedule_trigger_param

MyJob2

package com.tzp.quartz02.quaertz;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()+"-->携带参数个数:"+jobDataMap.size());} }

MyJob3

package com.tzp.quartz02.quaertz;import lombok.extern.slf4j.Slf4j; import org.quartz.*; import org.springframework.stereotype.Component;import java.util.Date;@Component @Slf4j public class MyJob3 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"));} }

这个类负责控制我们创建的两张中间表和Quartz的内置表中的业务逻辑,比如当我们中间表的状态为0时，我们定时任务就需要停止，那么就需要把内置表中的相关数据删除定时任务才会停止
