quartz在application中的使用

项目结构图：

TestMain.java

 package com;
 import org.quartz.Scheduler;
 import org.quartz.impl.StdSchedulerFactory;

 public class TestMain {

     public static void main(String[] args) {

         try {
             // 设置quartz.properties的classpath
             System.setProperty("org.quartz.properties", "quartz/quartz.properties");
             Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
             scheduler.start();
         } catch (Exception ex) {
             ex.printStackTrace();
         }
     }
 }

MyQuartzJob.java

 package task;

 import org.quartz.Job;
 import org.quartz.JobExecutionContext;
 import org.quartz.JobExecutionException;

 public class MyQuartzJob implements Job {
     private static int num = 0;
     @Override
     public void execute(JobExecutionContext arg0) throws JobExecutionException {
         System.out.println("Hello World! " + num++);
     }
 }
