springboot整合quartz进行数据库存储

Spring整合Quartz

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”

导入pom依赖：

 
	org.quartz-scheduler
	quartz-jobs
	2.2.1
   
   
   	org.springframework.boot
   	spring-boot-starter-quartz
   

导入druid的依赖

 
	com.alibaba
	druid-spring-boot-starter
	1.1.10
   

添加quartz.properties文件

建立配置类 QuartzConfiguration（quartz调度框架与spring框架整合的配置类，主要是要将org.quartz.Scheduler交给spring进行管理）
1、将调度器交给spring进行管理，调度器就是对quartz.properties进行建模读取 ，生产的调度工厂，然后调度工厂生产出来的调度器

package com.xhh.quartz02.config;

import com.xhh.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;

    //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();
    }
}

读取数据库中表达式启动定时任务

（每5s执行）
另外就是还需要自己创建两个表，一是调度表（触发器），二是调度表的参数表
调度表里就是所有的定时任务，参数表呢就是如果定时任务所要传递的参数
然后用mybatis逆向生成这两张表的实体类和mapper

ScheduleTriggerMapper
这个方法是查询出所有定时任务

/**
     * 查询触发器中包含的所有任务
     * @return
     */
    List queryScheduleTriggerLst();

ScheduleTriggerParamMapper
查询出当前任务类所需的参数

/**
     * 查询出当前任务类对应所需的参数
     * @param triggerId
     * @return
     */
    List queryScheduleParamLst(Integer triggerId);

MyJob1

package com.xhh.quartz02.quaertz;

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 MyJob1 implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("MyJob是一个空的任务计划,时间："+new Date().toLocaleString());
    }
}

Spring自带定时任务每10s执行一次，查询自定义触发器表，获取到具体的作业类及任务表达式，quartz的任务为每5s执行一次，所以打印如上

更改定时任务状态
更改数据库调度器表t_schedule_trigger的state状态

当禁用该触发器时，那么程序只会执行spring自带的定时任务，每10s执行一次查询，所以打印语句如上。

定时任务中携带参数
