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：

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

案例中需要观察表数据变化的表

-- 自定义的业务表
SELECT * FROM t_schedule_trigger;
SELECT * FROM t_schedule_trigger_param;

-- quartz调度框架自带的表
SELECT * FROM qrtz_scheduler_state;
SELECT * FROM qrtz_cron_triggers;
SELECT * FROM qrtz_simple_triggers
SELECT * FROM qrtz_triggers;
SELECT * FROM qrtz_job_details;

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
