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

package com.spring.test;public class ExampleBusinessObjec { public void doIt() {    System.out.println("ExampleBusinessObjec...");  }}

以下是 application.xml
