Spring MVC应用web.xml两种配置

环境：

Spring 3.2.8

JDK1.6

Tomcat6.x

1、亲测可用

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 </init-param>
 </filter>
 <filter-mapping>
 <filter-name>encodingFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>

2、亲测不可用，网上有人说可用。

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 <display-name>springmvc app</display-name>
 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath*:conf/springdemo-servlet.xml</param-value>
 </context-param>
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
 <servlet>
 <servlet-name>springMVC</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <init-param>

 <param-value>false</param-value>
 </init-param>
 <init-param>
 <param-name>publishEvents</param-name>
 <param-value>false</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>
 <filter>
 <filter-name>encodingFilter</filter-name>
 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
 <init-param>
 <param-name>encoding</param-name>
 <param-value>UTF-8</param-value>
 </init-param>
 <init-param>
 <param-name>forceEncoding</param-name>
 <param-value>true</param-value>
 </init-param>
 </filter>
 <filter-mapping>
 <filter-name>encodingFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>

启动后报错：
