SpringBoot+Quartz+数据库存储

SpringBoot+Quartz+数据库存储

Spring整合Quartz

a、quartz调度框架是有内置表的
进入quartz的官网 添加链接描述，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

下载完成后是这个样子

quartz项目

quartz默认的配置

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

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

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 {//这个对象Spring会帮我们自动注入进来 AutowireCapableBeanFactory自动装配@Autowiredprivate AutowireCapableBeanFactory autowireCapableBeanFactory;//重写创建Job任务的实例方法@Overrideprotected 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);} }

创建调度器schedule，交给spring进行管理

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

读取数据库来开启定时任务

t_schedule_trigger——param,管理传递的参数

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是一个空的任务计划,时间："+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()+"-->携带参数个数:"+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()+"-->MyJob2参数传递name="+jobDataMap.get("name")+",score="+jobDataMap.get("score"));} }

主要的业务逻辑类，这个类负责控制我们创建的两张中间表和Quartz的内置表中的业务逻辑,比如当我们中间表的状态为0时，我们定时任务就需要停止，那么就需要把内置表中的相关数据删除定时任务才会停止

ScheduleService

QuartzController

package com.lzy.quartz02.controller;import com.lzy.quartz02.entity.ScheduleTrigger; import com.lzy.quartz02.service.ScheduleTriggerService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.ModelAndView;import java.util.List;@Controller @RequestMapping("/quartz") public class QuartzController {@Autowiredprivate ScheduleTriggerService scheduleTriggerService;@RequestMapping("/list")public ModelAndView getAll(){ModelAndView mv = new ModelAndView();List<ScheduleTrigger> list = scheduleTriggerService.queryScheduleTriggerList();mv.addObject("quartzList",list);mv.setViewName("list");return mv;}@RequestMapping("/edit")public String editStatus(ScheduleTrigger scheduleTrigger){int n = scheduleTriggerService.updateByPrimaryKeySelective(scheduleTrigger);return "redirect:/quartz/list";}@RequestMapping("/proSave/{id}")public ModelAndView proSave(@PathVariable(value = "id") Integer id){ModelAndView mv=new ModelAndView();ScheduleTrigger scheduleTrigger = scheduleTriggerService.selectByPrimaryKey(id);mv.addObject("schedule",scheduleTrigger);mv.setViewName("edit");return mv;} }
