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>
