先看一个案例
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)); } }
spring配置文件如下:

测试类
package com.jCuckoo.demo; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class MainTest { public static void main(String[] args) { ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); Singer singer=(Singer) context.getBean("singer"); } }
