监听器里的东西为什么会在tomcat启动时加进去？
程序代码：控制台输出如下： 信息: Deploying web application directory qi002 非法文字过滤初始化 2011-10-5 23:20:19 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory qi003 添加application范围属性，属性名com.sun.faces.config.WebConfiguration com.sun.faces.config.WebConfiguration@bd4dc2 (这怎么被加进来了？？？) 2011-10-5 23:20:19 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory ROOT 2011-10-5 23:20:19 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory test 2011-10-5 23:20:19 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory test.myeclipse.bak 2011-10-5 23:20:20 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory test1 2011-10-5 23:20:20 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory test2 2011-10-5 23:20:20 org.apache.catalina.startup.HostConfig deployDirectory 信息: Deploying web application directory test3 2011-10-5 23:20:20 org.apache.coyote.http11.Http11Protocol start 信息: Starting Coyote HTTP/1.1 on http-8080 2011-10-5 23:20:20 org.apache. init 信息: JK: ajp13 listening on /0.0.0.0:8009 2011-10-5 23:20:20 org.apache.jk.server.JkMain start 信息: Jk running ID=0 time=0/31 config=null 2011-10-5 23:20:20 org.apache.catalina.startup.Catalina start 信息: Server startup in 3288 ms 添加application范围属性，属性名org.apache.jasper.runtime.JspApplicationContextImpl org.apache.jasper.runtime.JspApplicationContextImpl@a33d00 添加application范围属性，属性名name tom 替换application范围属性，属性名name 移除applocation范围属性,属性名name
程序代码：
监听器代码
package net.qijiabin.listener;
import javax.servlet.ServletContextAttributeEvent;
import javax.servlet.ServletContextAttributeListener;
public class MyServletContextAttributeListener implements ServletContextAttributeListener{
public void attributeAdded(ServletContextAttributeEvent scab) {
System.out.println("添加application范围属性，属性名"+scab.getName()+" "+scab.getValue());
}
public void attributeRemoved(ServletContextAttributeEvent scab) {
System.out.println("移除applocation范围属性,属性名"+scab.getName());
}
public void attributeReplaced(ServletContextAttributeEvent scab) {
System.out.println("替换application范围属性，属性名"+scab.getName());
}
}
程序代码：
web.xml配置如下
<listener>
<listener-class>
net.qijiabin.listener.MyServletContextAttributeListener
</listener-class>
</listener>
程序代码：
测试代码如下
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
