SpringBoot+Quartz实现数据库存储和简单的使用layui对定时任务进行crud

基本环境搭建

导入quartz所需要的内置表
quartz 如果要将定时任务的数据持久化到数据库就需要导入quartz的内置表

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，你是啥数据库就导入啥对应的 脚本就好了

ps: table_mysql_innodb.sql 这个是针对 mysql中innodb 这个引擎的，如果你使用的是这个引擎就导入这个吧

quartz 内置表结构：

自定义的业务表

-- 注意：job_name存放的任务类的全路径，在quartz中通过jobName和jobGroup来确定trigger的唯一性，所以这两列为联合唯一索引
create table t_schedule_trigger
(
  id int primary key auto_increment,                                -- ID
  cron varchar(200) not null,                                       -- 时间表达式
  status char(1) not null,                                          -- 使用状态 0：禁用   1：启用
  job_name varchar(200) not null,                                   -- 任务名称
  job_group varchar(200) not null,                                  -- 任务分组  
  unique index(job_name,job_group)
);

-- 额外添加到任务中的参数
create table t_schedule_trigger_param
(
  param_id int primary key auto_increment,                                -- ID
  name varchar(200) not null,                                             -- 参数名
  value varchar(512),                                                     -- 参数值
 
  schedule_trigger_id int not null,                                       -- 外键：引用t_schedule_trigger(id)
  foreign key(schedule_trigger_id) references t_schedule_trigger(id)
);

案例中需要观察表数据变化的表

-- 自定义的业务表
SELECT * FROM t_schedule_trigger;
SELECT * FROM t_schedule_trigger_param;

-- quartz调度框架自带的表
SELECT * FROM qrtz_scheduler_state;
SELECT * FROM qrtz_cron_triggers;
SELECT * FROM qrtz_simple_triggers
SELECT * FROM qrtz_triggers;
SELECT * FROM qrtz_job_details;

创建springboot项目
这是此处项目所要用到的启动器

maven中还需添加：

修改quartz数据源为 Druid

说明：
quartz 需要用到数据库连接池，Quartz 2.0 以前默认使用 DBCP。Quartz 2.0 以后 默认C3P0（包含2.0）。下面我们要将数据源修改为 Druid

基本步骤：
（1）导入依赖（上面已经导入了）
（2）导入DruidConnectionProvider.java
（3）修改quartz.properties配置

导入DruidConnectionProvider.java

package com.cpc.util;

import com.alibaba.druid.pool.DruidDataSource;
import org.quartz.SchedulerException;
import org.quartz.utils.ConnectionProvider;

import java.sql.Connection;
import java.sql.SQLException;

在项目中添加quartz.properties文件(这样就不会加载自带的properties文件),此文件的内容主要分为：scheduler，ThreadPool，JobStore，plugin，Datasources等部分，覆盖properties文件的目的是覆盖默认的数据源，更换为druid的数据配置

导入 MyJobFactory，让job类实现bean主任的功能

package com.cpc.config;

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 {

    //这个由Spring自动注入
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    //重写Job任务对象的创建实例方法
    @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);
        //这个时候 jobInstance 已经交给spring管理
        return jobInstance;
    }
}

QuartzConfiguration.java（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）

package com.cpc.config;


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();
    }
}

案例

下面是我使用代码生成工具生成的简单对 t_schedule_trigger 和 t_schedule_trigger_param 表的 curd


在生成的curd上在加了点方法：
TScheduleTriggerMapper.java

java:
    /**
     * 查询触发器中包含的所有任务
     * @return
     */
    List<TScheduleTrigger> queryScheduleTriggerLst();
xml:
    <select id="queryScheduleTriggerLst" resultMap="TScheduleTriggerMap">
        select id, cron, status, job_name, job_group
        from t_schedule_trigger
    </select>   
注：此处省略service 代码 

TScheduleTriggerParamMapper.java

java:
    /**
     * 查询出当前任务类对应所需的参数
     * @param triggerId
     * @return
     */

读取数据库中表达式启动定时任务

数据库表t_schedule_trigger配置

MyJob.java

package com.cpc.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 {

    @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


应为spring自带的定时任务会没10秒指向一次所有当我们对数据库进行修改的时候到了对应的时间点就刷新了

定时任务中携带参数

t_schedule_trigger

t_schedule_trigger_param

MyJobParam

package com.cpc.job;

import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @Description:
 * @Author: cpc
 * @Date: 2019-11-15 18:40
 * @Version: V1.0
 */
@Component
@Slf4j
public class MyJobParam implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        JobDetail jobDetail =
                jobExecutionContext.getJobDetail();
        JobDataMap jobDataMap = jobDetail.getJobDataMap();
        System.out.println(new Date().toLocaleString()+"-->携带参数个数:"+jobDataMap.size());
    }

}

程序执行spring自带的定时任务，每10s执行一次查询，查询t_schedule_trigger表，调度器是需要携带参数的，携带的参数在t_schedule_trigger_param表中，所以一开始调度器启动的时候需要查询t_schedule_trigger_param表数据，最终打印语句如上。

更改定时任务规则

t_schedule_trigger

t_schedule_trigger_param
