MyJob.java（自定义的作业类(任务类)）：

package com.xxx.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

//自定义作业类(任务类)
public class MyJob {
	public void run() {
		System.out.println("自定义的作业类执行了：" + 
				new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
	}
}

App.java（测试类）：

package com.xxx.quartz;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
	public static void main(String[] args) {
		//创建Spring容器,就会根据配置文件配置的调度工厂自动进行任务调度
		new ClassPathXmlApplicationContext("applicationContext.xml");
	}
