本人spring新手，初玩是spring的感覺就是坑爹的配置檔案，為此寫此文為正在苦苦掙扎於spring配置檔案的同學簡單的解釋下配置檔案。

歡迎拍磚。

先來看web.xml配置檔案：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<display-name></display-name>
	<welcome-file-list>
		<welcome-file>login.jsp</welcome-file>
		<welcome-file>index.jsp</welcome-file>

	</welcome-file-list>
	<!-- 宣告spring的核心類（其實是一個servlet，所以也逃不了要宣告），同時此處載入spring的配置檔案 -->
	<servlet>
		<servlet-name>dipatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/applicationContext.xml</param-value>
		</init-param>
	</servlet>
	<!-- 對那種請求進行轉發 -->
	<servlet-mapping>
		<servlet-name>dipatcher</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	<!-- 定義編碼過濾器，對中文等進行重新編碼，去除該過濾器則中文亂碼 -->
	<filter>
		<filter-name>Set Character Encoding</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>Set Character Encoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
</web-app>
 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
	<!-- 表示層的宣告：主要關於表示層字首路徑（如下：/view/）和字尾路徑（如下：.jsp）. 這麼宣告代表你的表示層檔案都在/view/下，而且都是.jsp檔案 -->

	<!-- Request Mapping -->
	<bean id="urlMapping"

	<bean id="loginAction" class="org.lee.springmvc.demo.LoginAction">
		<!-- 此類用於提取自動提取表單並填充該類（因此，沒有get、set是會報錯的），這是非常方便的 -->
