springboot整合Quartz
讀取數據庫來開啟定時任務（案例）
項目目錄
首先我們要知道我們整合Quartz需要哪些步驟
1、首先我們需要進入Quartz官網，下載我們使用需要的內置表sql
官網：http://www.quartz-scheduler.org/
下載下來是一個完整的文件夾，我們需要進入docs–>dbTables，然后在里面找你需要的數據類型的sql，然后把sql文件導入你的數據庫
如我的是mysql數據庫，它里面有11張表，這些表是我們后面操作Quartz需要的
2、創建springboot項目，導入相關pom,下面是我項目中用到的依賴
還有一些依賴是它沒有整合進去的，需要我們自己導入
<dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz-jobs</artifactId><version>2.2.1</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency>3、Quartz默認的連接池是c3p0，如果你的連接池不同需要直接替換它的配置文件，比如我用的連接池是druid，就需要自己改配置（如果就用c3p0就不需要改）
Druid連接池Quartz的工具類
DruidConnectionProvider

MyJobFactory
package com.liuxia.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);} }然后把剛剛寫的配置全部丟進我們的配置類中
QuartzConfiguration
讀取數據庫來開啟定時任務（案例）
那么我們還需要自己創建兩張表，通過這兩張表和Quartz的內置表來管理動態的定時任務,表里面的數據我們測試用的數據
t_schedule_trigger，管理具體的任務，
id：標識列
cron：表達式
status（0關閉，1開啟）是否開啟
job_name：job的name
job_group：job的group
t_schedule_trigger——param,管理傳遞的參數
然后用mybatis逆向生成這兩張表的實體類和mapper
這是我的3個job類
MyJob
MyJob1
