Quartz分布式定时任务执行和调度
0.创建数据库表
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

# I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

1.添加依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
2.配置Job类
package com.zhuantai.community.quartz;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
/**
* @author ANTIA1
* @date 2021/8/1 22:30
*/
public class AlphaJob implements Job {
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
System.out.println(Thread.currentThread().getName() + ": execute a quartz job.");
}
}
3.配置Config
package com.zhuantai.community.config;
import com.zhuantai.community.quartz.AlphaJob;
import org.quartz.JobDataMap;
import org.quartz.JobDetail;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.scheduling.quartz.SimpleTriggerFactoryBean;
/**
* 配置 -> 数据库 -> 调用
* @author ANTIA1
* @date 2021/8/1 22:31
*/
@Configuration
public class QuartzConfig {
// FactoryBean可简化Bean的实例化过程:
// 1.通过FactoryBean封装了Bean的实例化过程
// 2.将FactoryBean装配到Spring容器里
// 3.将FactoryBean注入给其他的Bean
// 4.该Bean得到的是FactoryBean所管理的对象实例.
/**
* 配置 JobDetail
* @return
*/
@Bean
public JobDetailFactoryBean alphaJobDetail(){
JobDetailFactoryBean factoryBean = new JobDetailFactoryBean();
factoryBean.setJobClass(AlphaJob.class);//设置任务类
factoryBean.setName("alphaJob");//设置任务名
factoryBean.setGroup("alphaJobGroup");//设置组名
factoryBean.setDurability(true);//任务是否长久保存,不会被删除
factoryBean.setRequestsRecovery(true);//任务是否可以恢复
return factoryBean;
}
/**
* 配置 Trigger (SimpleTriggerFactoryBean,CronTriggerFactoryBean)
* @param alphaJobDetail
* @return
*/
@Bean
public SimpleTriggerFactoryBean alphaTrigger(JobDetail alphaJobDetail){
SimpleTriggerFactoryBean factoryBean = new SimpleTriggerFactoryBean();
factoryBean.setJobDetail(alphaJobDetail);//对哪个任务进行触发,根据形参名进行区分
factoryBean.setName("alphaTrigger");
factoryBean.setGroup("alphaTriggerGroup");
factoryBean.setRepeatInterval(3000);//执行任务的频率
factoryBean.setJobDataMap(new JobDataMap());//存储job工作的状态
return factoryBean;
}
}
4.删除job
package com.zhuantai.community;
import org.junit.jupiter.api.Test;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
/**
* @author ANTIA1
* @date 2021/8/1 22:55
*/
@SpringBootTest
public class QuartzTests {
@Autowired
private Scheduler scheduler;
@Test
public void testDeleteJob() throws SchedulerException {
scheduler.deleteJob(new JobKey("alphaJob","alphaJobGroup"));
}
}
5.配置文件
