使用spring3 配置自动任务

1.首先配置 spring3 的配置文件

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xmlns:task="http://www.springframework.org/schema/task"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
  http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
  http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">

 

<context:component-scan base-package="test.jdbc" />

     <!-- 线程数目 -->
     <task:executor id="executor" pool-size="10" />
     <!-- 定时器数目 -->
 <task:scheduler id="scheduler" pool-size="10" />
 <task:annotation-driven executor="executor" scheduler="scheduler" />

</beans>

 

 

2.建立实体类

 

package test.jdbc;

import java.util.Calendar;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class Timer {
 private static final Logger log = LoggerFactory.getLogger(Timer.class);
 
 //固定频率每5秒钟执行一次
 @Scheduled(fixedDelay=5000)
 public void run(){
  log.info("time{}",Calendar.getInstance().getTimeInMillis());
  
 }
 
 //在每小时的 32分钟到55分钟之间每2秒钟执行一次
 @Scheduled(cron="*/2 32-55 * * * *")
 public void runTimeHour(){
  log.info("...........................hour to hor");
 }
 
 
 
}

 

 

 

3.执行结果：
