Spring MVC 基本配制

WEB.XML 文件中的配制：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
        http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <!--
            init-param 参数 contextConfigLocation 用来指定 Spring 的配制文件, classpath: 是指 WEB-INF/classes 目录
            这个参数也可以不指定，如果不指定，spring 默认查找 WEB-INF/classes/<servlet-name>-servlet.xml 的文件。
        -->
        <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:springmvc-servlet.xml</param-value>
          </init-param>
          <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

springmvc-servlet.xml 配制文件：
