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
