1. Quartz 官方
2. Quartz教程 - 易百教程

安装

• 说明
  1. 其是任务调度框架
  2. 基于Maven
  3. Quartz2
• 安装
  • 安装包pom

    <dependencies>
      <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.1</version>
      </dependency>
    </dependencies>
    

  • quartz.properties
    • 路径
      src/main/resources
    • 内容

      org.quartz.scheduler.instanceName = MyScheduler
      org.quartz.threadPool.threadCount = 3
      org.quartz.jobStore.class =org.quartz.simpl.RAMJobStore
      

  • 建立Job（测试Job）

    package com.mingwang.simpleapp;
    
    import org.quartz.Job;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    
    public class HelloJob implements Job
    {
        public void execute(JobExecutionContext context)
                throws JobExecutionException {
    
            System.out.println("Hello Quartz!");
    
        }
    }
    

  • 运行

    package com.mingwang.simpleapp;
    
    import org.quartz.*;
    import org.quartz.impl.StdSchedulerFactory;
    
    /**
     * Created by mingwang on 2017/10/28.
     */
    public class Test {
    
        public static void main(String [] args) {
            quartz();
        }
    
        public static void quartz()
        {
            JobDetail job = JobBuilder.newJob(HelloJob.class)
                    .withIdentity("dummyJobName", "group1").build();
    
            // Trigger the job to run on the next round minute
            Trigger trigger = TriggerBuilder
                    .newTrigger()
                    .withIdentity("dummyTriggerName", "group1")
                    .withSchedule(
                            SimpleScheduleBuilder.simpleSchedule()
                                    .withIntervalInSeconds(5).repeatForever())
                    .build();
    
            // schedule it
            Scheduler scheduler = null;
            try {
                scheduler = new StdSchedulerFactory().getScheduler();
                scheduler.start();
                scheduler.scheduleJob(job, trigger);
            } catch (Exception e) {
    
            }
        }
    }
