quartz

导入maven依赖

<dependency>    <groupId>org.quartz-scheduler</groupId>    <artifactId>quartz</artifactId>    <version>2.3.0</version></dependency>

该依赖会自动加载其他的依赖包，比如

编写自定义的job类，继承job

package com.lckoo.bear.module.demo.quartz;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import java.time.LocalDate;import java.time.LocalTime;import java.time.format.DateTimeFormatter;/** * 定义自己的job任务 */public class MyJob implements Job{    @Override    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {        //编写具体的业务逻辑        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("d:MM:uuuu HH:mm:ss");        System.out.println("当前时间            "+LocalTime.now());        System.out.println("Hello World");    }}

创建 触发器和调度器

package com.lckoo.bear.module.demo.quartz;import org.quartz.*;import org.quartz.impl.StdSchedulerFactory;import org.springframework.scheduling.annotation.Scheduled;/** * test */public class QuartzTest {    public static void main(String[] args) {        //创建一个jobdetail实例，绑定job        JobDetail jobDetail = JobBuilder.newJob(MyJob.class)                .withIdentity("job1","jobgroup")                .build();        //创建一个触发器        Trigger trigger = TriggerBuilder.newTrigger()                .withIdentity("trigger1","group1")                .startNow()                .withSchedule(                        SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever())                .build();        //创建scheduler 调度器        SchedulerFactory schedulerFactory = new StdSchedulerFactory();        try {            Scheduler scheduler = schedulerFactory.getScheduler();            scheduler.scheduleJob(jobDetail,trigger);            scheduler.start();        } catch (SchedulerException e) {            e.printStackTrace();        }    }}
