job类

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

public class HelloJob implements Job{

    @Override

    public void execute(JobExecutionContext context)

            throws JobExecutionException {

        System.out.println("这是个Job!");

    }

}

 

1. 作业内容
2. 调度器
3. 执行时间

三者结合完成各种调度
