SpringBoot+Quartz+数据库存储

1、Spring整合Quartz
1、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docsdbTables下有常用数据库创建quartz表的脚本，例如：“tables_mysql.sql”

2、导入pom依赖

导入自定义quartz.properties文件，因为quartz默认使用的是c3p0数据库连接池，我们要使用Druid

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)
);
