SpringBoot+Quartz+數據庫存儲

Spring整合Quartz

a、quartz調度框架是有內置表的
進入quartz的官網 添加鏈接描述，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”

table_mysql.sql
table_mysql_innodb.sql
上述兩者所有的數據庫引擎不一樣

下載完成后是這個樣子

quartz項目

quartz默認的配置

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

自定義MyJobFactory，解決spring不能在quartz中注入bean的問題

package com.lzy.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 AutowireCapableBeanFactory自動裝配@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);} }

創建調度器schedule，交給spring進行管理

package com.lzy.quartz02.config;import com.lzy.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;//創建調度器工廠@Beanpublic SchedulerFactoryBean schedulerFactoryBean(){//1.創建SchedulerFactoryBean//2.加載自定義的quartz.properties配置文件//3.設置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();} }

讀取數據庫來開啟定時任務

t_schedule_trigger——param,管理傳遞的參數

MyJob

package com.lzy.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.err.println("MyJob是一個空的任務計劃,時間："+new Date().toLocaleString());} }

MyJob1

package com.lzy.quartz02.job;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;@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());} }

MyJob2

package com.lzy.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()+"-->MyJob2參數傳遞name="+jobDataMap.get("name")+",score="+jobDataMap.get("score"));} }

主要的業務邏輯類，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
