spirng 支持的三种定时器学习笔记

以下是三个定时器的类

package com.spring.test;

import java.util.TimerTask;

public class ExamplesTimer extends TimerTask{
	@Override
	public void run() {
		System.out.println("run......");
	}
}

package com.spring.test;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class ExamplesJob extends QuartzJobBean {
	private int timeout ;
	
	public void setTimeout(int timeout) {
		this.timeout = timeout;
	}

	@Override
	protected void executeInternal(JobExecutionContext arg0)
			throws JobExecutionException {
			System.out.println("ExamplesJob.....");
	}
}

package com.spring.test;

public class ExampleBusinessObjec {
	 public void doIt() {
		    System.out.println("ExampleBusinessObjec...");
		  }
}
