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：

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