1、Spring整合Quartz
a、quartz調度框架是有內置表的，使用quartz就必須使用它的內置表，下載內置表在以下官網，自行下載
進入quartz的官網http://www.quartz-scheduler.org/，點擊Downloads，
下載后在目錄\docs\dbTables下有常用數據庫創建quartz表的腳本，例如：“tables_mysql.sql”，我使用的MySQL，根據自己的版本來定
因為我創建的項目是springboot項目，在創建的時候quartz的pom依賴已經導入進來，但是它還缺少另外關于quartz的jar包，
<dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz-jobs</artifactId><version>2.2.1</version></dependency> quartz默認使用的是C3P0連接池quartz需要使用C3P0連接池將數據持久化到數據庫Quartz各版本數據庫連接池技術更新情況Quartz 2.0 以前 DBCPQuartz 2.0 以后 C3P0（包含2.0）我這里使用的Druid連接池，所以導入它的jar包
<dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifact Id><version>1.1.10</version></dependency>c、在項目中添加quartz.properties文件(這樣就不會加載自帶的properties文件)
此文件的內容主要分為：scheduler，ThreadPool，JobStore，plugin，Datasources等部分，
覆蓋properties文件的目的是覆蓋默認的數據源，更換為druid的數據配置
d、自定義MyJobFactory，解決spring不能在quartz中注入bean的問題
e、創建調度器schedule，交給spring進行管理
f、創建自定義任務
g、更新quartz中的任務
h、自定義任務表與quartz內置表的區分
要搞清楚一個問題：從數據庫讀取任務信息動態生成定時任務，和把quartz持久化到數據庫是沒有關系的。前者是我們自己定義的業務表，而后者是quartz使用自己的表來存儲信息。持久化到數據庫后，就算服務器重啟或是多個quartz節點也沒關系，因為他們共享數據庫中的任務信息。
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 {//這個對象Spring會幫我們自動注入進來@Autowiredprivate AutowireCapableBeanFactory autowireCapableBeanFactory;//重寫創建Job任務的實例方法@Overrideprotected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {Object jobInstance = super.createJobInstance(bundle);//通過以下方式，解決Job任務無法使用Spring中的Bean問題autowireCapableBeanFactory.autowireBean(jobInstance);return super.createJobInstance(bundle);} }使用Druid它的數據源
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;/* #============================================================================ #

1、將調度器交給spring進行管理，調度器就是對quartz.properties進行建模讀取 ，生產的調度工廠，然后調度工廠生產出來的調度器
案例中需要觀察表數據變化的表
– 自定義的業務表 SELECT * FROM t_schedule_trigger; SELECT * FROM t_schedule_trigger_param;
– quartz調度框架自帶的表 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

（每5s執行）
另外就是還需要自己創建兩個表，一是調度表（觸發器），二是調度表的參數表
調度表里就是所有的定時任務，參數表呢就是如果定時任務所要傳遞的參數
需要請自行提取
鏈接：https://pan.baidu.com/s/1fbF1jmZVHqZsjhTO7jiCRA
提取碼：83j2
然后用mybatis逆向生成這兩張表的實體類和mapper
ScheduleTriggerMapper
這個方法是查詢出所有定時任務
ScheduleTriggerParamMapper
查詢出當前任務類所需的參數
這是我的3個job類
數據庫表t_schedule_trigger配置
MyJob1
Spring自帶定時任務每10s執行一次，查詢自定義觸發器表，獲取到具體的作業類及任務表達式，quartz的任務為每5s執行一次，所以打印如上
更改定時任務狀態
更改數據庫調度器表t_schedule_trigger的state狀態
當禁用該觸發器時，那么程序只會執行spring自帶的定時任務，每10s執行一次查詢，所以打印語句如上。
定時任務中攜帶參數
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()+"-->攜帶參數個數:"+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()+"-->MyJob2參數傳遞name="+jobDataMap.get("name")+",score="+jobDataMap.get("score"));} }這個類負責控制我們創建的兩張中間表和Quartz的內置表中的業務邏輯,比如當我們中間表的狀態為0時，我們定時任務就需要停止，那么就需要把內置表中的相關數據刪除定時任務才會停止
ScheduleTriggerServiceImpl
QuartzController
package com.tzp.quartz2.controller;import com.tzp.quartz2.model.ScheduleTrigger; import com.tzp.quartz2.service.ScheduleTriggerService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView;import java.util.List;/*** @author 心如止水* @site www.tzp.com* @create 2019-11-16 18:39*/ @Controller @RequestMapping("/quartz") public class QuartzController {@Autowiredprivate ScheduleTriggerService scheduleTriggerService;@RequestMapping("/list")public ModelAndView getAll(){ModelAndView mv = new ModelAndView();List<ScheduleTrigger> list = scheduleTriggerService.queryScheduleTriggerLst();mv.addObject("quartzList",list);mv.setViewName("index");return mv;}@RequestMapping("/edit")public String editStatus(ScheduleTrigger scheduleTrigger){int n = scheduleTriggerService.updateByPrimaryKeySelective(scheduleTrigger);return "redirect:/quartz/list";}@RequestMapping("/add")public String addStatus(ScheduleTrigger scheduleTrigger){int n = scheduleTriggerService.insert(ScheduleTrigger record);return "redirect:/quartz/list";}@RequestMapping("/proSave/{id}")public ModelAndView proSave(@PathVariable(value = "id") Integer id){ModelAndView mv=new ModelAndView();ScheduleTrigger scheduleTrigger = scheduleTriggerService.selectByPrimaryKey(id);mv.addObject("schedule",scheduleTrigger);mv.setViewName("edit");return mv;}}前端頁面 list.html
