maven配置spring-mvc请求到不了controller

最近自己想用maven搭建spring-mvc项目，按照结构搭建的最后请求到不了

 controller2015-06-17 17:29:30 [org.springframework.web.servlet.DispatcherServlet]-[DEBUG] Bound request context to thread: org.apache.catalina.connector.RequestFacade@1e70f682015-06-17 17:29:30 [org.springframework.web.servlet.DispatcherServlet]-[DEBUG] DispatcherServlet with name 'spring' processing GET request for [/MavenDemo/index.do]2015-06-17 17:29:30 [org.springframework.web.servlet.DispatcherServlet]-[DEBUG] Testing handler map [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping@7d554f59] in DispatcherServlet with name 'spring'2015-06-17 17:29:30 [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping]-[DEBUG] No handler mapping found for [/index.do]2015-06-17 17:29:30 [org.springframework.web.servlet.DispatcherServlet]-[DEBUG] Testing handler map [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping@2c0ea67] in DispatcherServlet with name 'spring'2015-06-17 17:29:30 [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping]-[DEBUG] No handler mapping found for [/index.do]

下面是配置：

web.xml

  <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:conf/spring.xml;        </param-value>    </context-param>    <!-- 设计路径变量值 -->    <context-param>        <param-name>webAppRootKey</param-name>        <param-value>springmvc.root</param-value>    </context-param>    <!-- Spring字符集过滤器 -->    <filter>        <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- 日志记录 -->    <context-param>        <!-- 日志配置文件路径 -->        <param-name>log4jConfigLocation</param-name>        <param-value>classpath:conf/log4j.properties</param-value>    </context-param>    <context-param>        <!-- 日志页面的刷新间隔 -->        <param-name>log4jRefreshInterval</param-name>        <param-value>6000</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>    </listener>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- springMVC核心配置 -->    <servlet>        <servlet-name>spring</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:conf/spring-mvc.xml</param-value>        </init-param>        <load-on-startup>2</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>spring</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping>    <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list>

spring-mvc.xml

 <context:component-scan base-package=""com.tarena""/>    <mvc:annotation-driven/>   <bean id=""jacksonMessageConverter"" class=""org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"">            <property name=""supportedMediaTypes"">            <list>                <value>text/html;charset=UTF-8</value>            </list>        </property>    </bean>   <!-- 对模型视图添加前后缀 -->     <bean id=""viewResolver"" class=""org.springframework.web.servlet.view.InternalResourceViewResolver""      p:prefix=""/WEB-INF/jsp/"" p:suffix="".jsp""/>

UserController.java

 package com.tarena.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping(""/"")public class UserController {    @RequestMapping(""index"")    public String index(){        return ""index"";    }}

tomcat启动起来之后访问http://localhost:8080/MavenDemo可以正常跳转到欢迎页面，但是http://localhost:8080/MavenDemo/index.do就不能跳转到对应页面了。

解决方案

@Controller
@RequestMapping(""/index"")
public class UserController {
@RequestMapping(""index"")
public String index(){
return ""index"";
}
}

这样写访问url是：http://localhost:8080/MavenDemo/index.do?index
你这样将action命名访问路径为“/”，那你怎么去区分不同的action 所有建议不要那样写。

解决方案二：
没有配置index.do的View与Action的映射关系

解决方案三：
你拦截的是@RequestMapping(""index"")，注意看清楚了http://localhost:8080/MavenDemo/index估计才可以

解决方案四：
mappimg注解改成inde.do
