  • 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~~~

     1 //spring开启task注解扫描就OK了
     2 //<context:component-scan base-package="com.cityhero.dao,com.cityhero.task"/>
     3 //<task:annotation-driven/>
     4 
     5 //搞一个BaseTask,常用的都扔进去
     6 package com.cityhero.task;
     7 
     8 import java.text.DateFormat;
     9 import java.text.SimpleDateFormat;
    10 
    11 import org.apache.log4j.Logger;
    12 import org.springframework.stereotype.Component;
    13 
    14 @Component
    15 public class BaseTask {
    17 protected static final DateFormat date_format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 18 } 19 20 //嗯....再搞一个测试类,继承BaseTask,配合一下. 21 package com.cityhero.task; 22 23 import java.util.Date; 24 25 import org.springframework.scheduling.annotation.Scheduled; 26 import org.springframework.stereotype.Component; 27 28 @Component 29 public class TaskTest extends BaseTask { 30 31 @Scheduled(cron="0/5 * * * * ?") //五秒执行一次 32 public void sayHellow() { 33 Date now = new Date(); 34 logger.info("Hello.My English is pool . . ." + date_format.format(now)); 35 } 36 }

     

    //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~
