web容器启动时，借助spring进行初始化操作

package com.net263.boss.util;

import org.springframework.context.ApplicationEvent;

import org.springframework.context.ApplicationListener;

@SuppressWarnings("unchecked")

public class springInitial implements ApplicationListener {

@Override

public void onApplicationEvent(ApplicationEvent arg0) {

for(int i =0;i<10;i++) {

System.out.println("hello world");

}

}

}

1.实现 ApplicationListener借口

2.重写 onApplicationEvent方法

3.将该类配置到ApplicationContext中<bean id="springInitial" class="com.net263.boss.util.springInitial"/>
