项目目录:
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:
把tables_mysql.sql导入自己的mysql数据库
然后导入pom依赖:

quartz默认的数据库连接池是c3p0,这里我用的是druid。

mybatis逆向生成工具和jdbc就不发了以前博客都有
读取数据库表来开启定时任务:
_schedule_trigger:管理具体的任务
id:标识列
cron:表达式
status(0关闭,1开启)是否开启
job_name:job的name
job_group:job的group
t_schedule_trigger_param,管理传递的参数
param_id:标识列
schedule_trigger_id:对应上面表的ID(表示是谁的参数)
t_schedule_trigger——param,管理传递的参数
测试类:
myjob

Myjob1
package com.cjh.quartz02.job; import lombok.extern.slf4j.Slf4j; import org.quartz.*; import org.springframework.stereotype.Component; import java.util.Date; @Component @Slf4j public class MyJob1 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()); } }
MyJob2
package com.cjh.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 { @Override public 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,当我们中间表的状态为0时,定时任务就需要停止,同时也要把内置表里面数据删除才停止

效果:
如果控制台出现错误信息为:
Error resolving template [list], template might not exist or might not be accessible by any of the configured Template Resolvers
在pom依赖中添加:
