SpringMVC的web.xml的配置。

大致配置如下：

<?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" xmlns:jsp="http://java.sun.com/xml/ns/javaee/jsp" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name></display-name>

  <!-- spring框架必须定义ContextLoaderListener，在启动Web容器时，自动装配Spring applicationContext.xml的配置信息 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <context-param>

 <!-- 指定Spring上下文配置文件 -->
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext.xml</param-value>
  </context-param>  
  <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

<!-- 指定SpringMVC配置文件 -->
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/spring-mvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <!-- 指定请求的后缀，可以随意写，这里用.html作为请求后缀 -->
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>
  
  <welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
</web-app>

或者：

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

  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
