篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot+quartz+数据库存储相关的知识，希望对你有一定的参考价值。
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：
导入pom依赖

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) );
