spring boot+Quartz+数据库存储
SpingBoot+Quartz+数据库存储
1、Spring整合Quartz
2、读取数据库中表达式启动定时任务1（每5s执行）
3、更改定时任务状态（启用/禁用），定时任务1停止
4、读取数据库中表达式启动定时任务2（每5s执行），在对应作业类中打印定时任务2携带的参数
5、读取数据库中表达式启动定时任务3（每5s执行改成每20s执行），更改数据库定时任务表达式，定时任务3对应执行策略相应发生改变。
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
导入pom依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
c、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
d、自定义MyJobFactory，解决spring不能在quartz中注入bean的问题
e、创建调度器schedule，交给spring进行管理
f、创建自定义任务
g、更新quartz中的任务
自定义任务表与quartz内置表的区分
要搞清楚一个问题：从数据库读取任务信息动态生成定时任务，和把quartz持久化到数据库是没有关系的。
前者是我们自己定义的业务表，而后者是quartz使用自己的表来存储信息。
持久化到数据库后，就算服务器重启或是多个quartz节点也没关系，因为他们共享数据库中的任务信息。
创建项目
自定义业务表
-- 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)
);

/**
* 查询出当前任务类对应所需的参数

List<ScheduleTriggerParam> queryScheduleParamLst(Integer triggerId);
}
ScheduleTriggerParamServiceImpl
package com.yuan.quartz02.service.impl; import com.yuan.quartz02.mapper.ScheduleTriggerParamMapper;
import com.yuan.quartz02.model.ScheduleTriggerParam;
import com.yuan.quartz02.service.ScheduleTriggerParamService;

读取数据库中表达式启动定时任务
myjob
package com.yuan.quartz02.quartz; 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
读取数据库中表达式启动定时任务
数据库表t_schedule_trigger配置
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。
MyJob1
package com.yuan.quartz02.quartz; import com.yuan.quartz02.service.ScheduleTriggerParamService;
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; @Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
JobDetail jobDetail =
jobExecutionContext.getJobDetail();
JobDataMap jobDataMap = jobDetail.getJobDataMap();
System.err.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，
调度器表中有两个调度器，都是每5s执行一次，其中一个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
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
控制器
QuartzController
package com.yuan.quartz02.controller; import com.yuan.quartz02.model.ScheduleTrigger;
import com.yuan.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.servlet.ModelAndView; import java.util.List; @Controller
@RequestMapping("/quartz")
public class QuartzController { @Autowired
private ScheduleTriggerService scheduleTriggerService; @RequestMapping("/list")
public ModelAndView getAll(){
ModelAndView modelAndView = new ModelAndView();
List<ScheduleTrigger> list = scheduleTriggerService.queryScheduleTriggerLst();
modelAndView.addObject("quartzList",list);
modelAndView.setViewName("/index");
return modelAndView;
} @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 modelAndView=new ModelAndView();
ScheduleTrigger scheduleTrigger = scheduleTriggerService.selectByPrimaryKey(id);
modelAndView.addObject("schedule",scheduleTrigger);
modelAndView.setViewName("/edit");
return modelAndView;
} }
