spring3使用task:annotation-driven开始定时

package com.jCuckoo.demo;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.scheduling.annotation.Scheduled;

public class Singer {

//@Scheduled(fixedDelay=1000)  //第一种方式
//fixedDelay延时多少毫秒，多少毫秒执行一次
　　/*
1 Seconds (0-59)
2 Minutes (0-59)
3 Hours (0-23)
4 Day of month (1-31)
5 Month (1-12 or JAN-DEC)
6 Day of week (1-7 or SUN-SAT)
7 Year (1970-2099)
取值：可以是单个值，如6；
也可以是个范围，如9-12；
也可以是个列表，如9,11,13
也可以是任意取值，使用*
*/
//0 * * * * * 代表每分钟执行一次
@Scheduled(cron="0 * * * * *")     //第二种方式

public void singing(){
Date date=new Date();
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
System.out.println(sdf.format(date));
}
}
