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++);
    }
}
