为什么80%的码农都做不了架构师？>>>

本文是基于Spring 3.2.18 编写的，所有依赖包见下图：

首先是web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">

    <!-- 应用显示名称 -->
	<display-name>my-web-app</display-name>
	
    <!-- Spring全局参数，目的是指定spring配置文件 -->
	<context-param>  
		<param-name>contextConfigLocation</param-name>  
		<param-value>/WEB-INF/config/spring3/applicationContext.xml</param-value>
	</context-param>  
	
    <!-- 定义spring DispatcherServlet，并将配置文件spring3-mvc.xml注入 -->
	<servlet>
		<servlet-name>spring3</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>  
			<param-name>contextConfigLocation</param-name>  
			<param-value>/WEB-INF/config/spring3/spring3-mvc.xml</param-value>
		</init-param>  
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring3</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

    <!-- 定义spring 监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
	</welcome-file-list>
	
</web-app>

然后介绍 applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
