HTTP Status 404 - servlet文件无法访问

[CAT_SEVEN]

利用SpringMVC做一个简单 的文件上传功能，web.xml配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1"
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_1.xsd"
>
  <display-name>Apr20_SpringMVC</display-name>
  
  <servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 指定spring的指定文件 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath*:spring-mvc.xml</param-value>
		</init-param>
	<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>*.from</url-pattern>
	</servlet-mapping>

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

url映射路径为*.from 可是无法跳转？
spring-mvc.xml文件如下：

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

如何解决？

你这问题问的，表示看不懂，找到重点在问吧，起码你把报错信息发来，访问路径发来吧

访问路径为：

http://localhost:8080/Apr20_SpringMVC/toUpload.from

报错信息是http404 message处为空白？
