使用Maven创建Spring MVC Web应用程序。请找到以下目录结构的图像。 web.xml，dispatcher-servlet.xml文件。我无法获得所需的index.jsp页面内容。我是新手，所以请任何人检查，让我在哪里犯错？

Web.xml中：

<web-app 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"
        version="2.5">
  <display-name>MongoSample</display-name>
    <welcome-file-list>
            <welcome-file>/jsp/index.jsp</welcome-file>
    </welcome-file-list>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

调度-servlet.xml中：

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

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <mvc:resources location="/css/" mapping="/css/**" cache-period="1314000"/>

    <!-- Factory bean that creates the Mongo instance -->
    <bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
        <property name="host" value="localhost" />
        <property name="port" value="27017"/>
    </bean>

    <!-- MongoTemplate for connecting and querying the documents in the database  --> 
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongo" ref="mongo" />
        <constructor-arg name="databaseName" value="test" />
    </bean>

    <!-- Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes -->
    <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsp/" />
      <property name="suffix" value=".jsp" />
   </bean> 
</beans>

                users.setLast_update_time(date);
            userService.saveUserService(users);
            return userService.getAllUserService();
         }                   
}

在Spring中你需要一个控制器（方法）来渲染jsp，这可能是一个正常的＆＃34;手＆＃34;书面控制员，或者像这样的某些人

<view-controller path="index.html*" view-name="index"/>
