Quartz database storage
2022-06-13 05:26:00 【Lee_ mons】
（ One ） build SpringBoot project
1. newly build spring project , Check quartz scheduler
2. Go to the official website to download quartz Built in table
3. find table-mysql The database script for is in idea Running scripts inside
4. Run the following sql Script
create table t_schedule_trigger
(
id bigint primary key auto_increment comment ' Trigger number ',
cron varchar(200) not null comment ' Flip-flop expression ',
status char(1) not null comment ' Trigger state : Ban Enable ',
job_name varchar(200) not null comment ' The name of the task : The full path of the stored task class ',
job_group varchar(200) not null comment ' The group in which the task is located ',
job_description varchar(200) not null comment ' Task description ',
trigger_description varchar(200) not null comment ' Trigger description ',
unique index (job_name, job_group) comment ' adopt jobName and jobGroup To make sure trigger Uniqueness , So these two columns are the joint unique index '
);
create table t_schedule_trigger_data
(
id bigint primary key auto_increment comment ' Data number ',
name varchar(200) not null comment ' The corresponding data name ',
value varchar(512) comment ' Corresponding data values ',
trigger_id bigint not null comment ' Foreign keys : quote t_schedule_trigger(id)',
foreign key (trigger_id) references t_schedule_trigger (id)
);5. Insert analog data into the two tables shipped out
（ Two ） Tool class parsing
1. Import pox.xml The configuration file

// Give this object an operation springBean The ability of
autowireCapableBeanFactory.autowireBean(jobInstance);
return super.createJobInstance(bundle);
}
}5. Import QuartzConfiguration Configuration class
effect ： Give the scheduler to spring management , In the future, the scheduler is required for other types of applications , Just inject it directly
package com.lsy.code.conf;
import com.lsy.code.util.MyJobFactory;

this.myJobFactory = myJobFactory;
}
/**

*/
@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
//1. establish SchedulerFactoryBean
SchedulerFactoryBean factoryBean = new SchedulerFactoryBean();
//2. Load custom quartz.properties The configuration file
factoryBean.setQuartzProperties(quartzProperties());
//3. Set up MyJobFactory
factoryBean.setJobFactory(myJobFactory);
return factoryBean;
}
@Bean
@SneakyThrows

PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
propertiesFactoryBean.afterPropertiesSet();
return propertiesFactoryBean.getObject();
}
@Bean
public Scheduler scheduler() {
return schedulerFactoryBean().getScheduler();
}
}
6. To write application.yml file
notes ： Remember to change the database connection name

}2.mapper class
Inherit common mapper

public List<ScheduleTriggerData> find(Long triggerId) {
Example example=new Example(ScheduleTriggerData.class);
example.createCriteria().andEqualTo("triggerId",triggerId);
return mapper.selectByExample(example);
}
}
Query all the methods because there is no method to query according to the foreign key , So we need example
package com.lsy.code.service;
