spring设置容器启动时运行线程类（可循环执行）

修改以下两文件，

1.spring设置容器启动时运行线程类

<?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"

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">  

<!-- 托管线程 -->

<bean id="messagePrinterTask" class="MessagePrinterTask">

</bean> 

<!-- 这样设置容器一启动就自动运行某个线程 start -->

 <bean id="springScheduleExecutorTask" class="org.springframework.scheduling.concurrent.ScheduledExecutorTask">

    <property name="runnable" ref="messagePrinterTask" /><!-- messagePrinterTask为线程类 -->

    <!-- 容器加载10秒后开始执行 -->

    <property name="delay" value="10000" />

    <!-- 每次任务间隔 5秒，循环执行该线程，删除该设定就容器启动后只执行一次-->

    <property name="period" value="5000" />

  </bean>  

    <bean id="springScheduledExecutorFactoryBean" class="org.springframework.scheduling.concurrent.ScheduledExecutorFactoryBean">

    <property name="scheduledExecutorTasks">

      <list>

        <ref bean="springScheduleExecutorTask" />

      </list>

    </property>

   </bean>

<!-- 这样设置容器一启动就自动运行某个线程 end -->

</beans>

测试运行

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**

 * Hello world!

 *

 */

public class App

{

    public static void main( String[] args )

    {

        ApplicationContext appContext = new ClassPathXmlApplicationContext("applicationContext.xml");

    }

}

结果
