maven配置spring-mvc请求到不了controller

Question

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

 controller

下面是配置：

web.xml

  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:conf/spring.xml;
        </param-value>

    </filter-mapping>

    <listener>

    <!-- springMVC核心配置 -->

    </servlet>

    </servlet-mapping>

        <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。

Answer 1

@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。
