springboot內建quartz

1、quartz排程架構是有内置表的,首先需要進入Quartz官網，下載下傳使用所需要的内置表sql

官網：http://www.quartz-scheduler.org/

自動生成表達式：http://cron.qqe2.com/

下載下傳下來是一個完整的檔案夾，我們需要進入docs–>dbTables，然後在裡面找你需要的資料類型的sql，然後把sql檔案導入你的資料庫

我的是mysql資料庫，它裡面有11張表，引入之個即可

2. 建立springboot項目，導入相關pom

3、Quartz預設的連接配接池是c3p0，如果連接配接池不同需要替換它的配置檔案，比如我用的連接配接池是druid，就需要自己改配置（如果就用c3p0就不需要改）

4、需要配置我們的JobFactory，因為我們在項目開發中是需要在Job中操作資料庫的，那麼當然需要把它交給spring管理，但是quartz本身是不支援的，是以我們需要修改它的底層代碼，讓我們的Job類能被spring所管理

MyJobFactory

package com.li.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
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    //重寫建立Job任務的執行個體方法
    @Override
    protected 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);
    }
}

quartz.properties

org.quartz.dataSource.qzDS.maxConnection: 10

配置類

QuartzConfiguration

剛剛的配置也加在這裡面

package com.li.quartz02.config;

import com.li.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 {

    @Autowired
    private MyJobFactory myJobFactory;

    //建立排程器工廠
    @Bean
        public SchedulerFactoryBean schedulerFactoryBean(){
            //1.建立SchedulerFactoryBean
            //2.加載自定義的quartz.properties配置檔案
            //3.設定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

讀取資料庫來開啟定時任務

建立兩張表，通過這兩張表和Quartz的内置表來管理動态的定時任務,表裡面的資料我們測試用的資料

t_schedule_trigger，管理具體的任務，

id：辨別列

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
