SpringBoot+Quartz+数据库存储

Spring整合Quartz
读取数据库来开启定时任务（案例）

Spring整合Quartz

a、quartz调度框架是有内置表的
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”

table_mysql.sql
table_mysql_innodb.sql
上述两者所有的数据库引擎不一样

点击下载

在这里插入图片描述
下载之后会得到以下这个

点击，把table_mysql表导入数据库中

注意：为了讲解内容方便，不涉及到页面，又能将功能展现出来，本篇博客采取的是spring自带的定时器与quartz调度框架一并使用

因为Quart本身自带一个quartz.properties 而我们需要现在需要改变这个配置，所有我们需要重写一个页面然后再去配置

d、自定义MyJobFactory，解决spring不能在quartz中注入bean的问题
MyJobFactory

package com.xyx.quertz02.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
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    //重写创建Job任务的实例方法
    @Override
    protected 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);
    }
}

QuartzConfiguration.java
创建调度器schedule，交给spring进行管理

package com.xyx.quertz02.config;

import com.xyx.quertz02.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;

    //创建调度器工厂
    @Bean
        public SchedulerFactoryBean schedulerFactoryBean(){
            //1.创建SchedulerFactoryBean
            //2.加载自定义的quartz.properties配置文件
            //3.设置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();
    }
}
