Spring定时器的使用详解

睡前没什么事儿,来祸害一下园子~~虽然我菜,但是我不会承认啊,哈哈哈

明天详细补充点儿吧,很晚了,不睡觉的程序员不是好程序员,我总能给自己找借口~~~

 //spring开启task注解扫描就OK了
 //<context:component-scan base-package="com.cityhero.dao,com.cityhero.task"/>
 //<task:annotation-driven/>

 //搞一个BaseTask,常用的都扔进去
 package com.cityhero.task;

 import java.text.DateFormat;
 import java.text.SimpleDateFormat;

 import org.apache.log4j.Logger;
 import org.springframework.stereotype.Component;

 @Component
 public class BaseTask {
     protected static final DateFormat date_format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
 }

 //嗯....再搞一个测试类,继承BaseTask,配合一下.
 package com.cityhero.task;

 import java.util.Date;

 import org.springframework.scheduling.annotation.Scheduled;
 import org.springframework.stereotype.Component;

 @Component
 public class TaskTest extends BaseTask {

     @Scheduled(cron="0/5 * * * * ?") //五秒执行一次
     public void sayHellow() {
         Date now = new Date();
         logger.info("Hello.My English is pool . . ." + date_format.format(now));
     }
 }

//启动起来就可以了,怎么样,是不是超级简单呢~对于我这种菜B来说,可以摆脱quartz啦!开心~
