        <servlet>

这是我的web.xml配置

 <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <context:component-scan base-package="com.last.controler" />

    <!-- Configures the @Controller programming model -->
    <mvc:annotation-driven />

    <!--Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->

    <!--</bean>-->

    <!--springMVC+thymeleaf的跳转页面配置-->
    <bean id="templateResolver"
          class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
        <property name="prefix" value="/WEB-INF/views/" />

        <property name="templateMode" value="HTML5" />
    </bean>

    <bean id="templateEngine"
          class="org.thymeleaf.spring4.SpringTemplateEngine">
        <property name="templateResolver" ref="templateResolver" />
    </bean>

    <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
        <property name="templateEngine" ref="templateEngine" />
    </bean>
</beans>

这是我的springmvc.xml配置

 package com.last.controler;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by R513M on 2016/6/28.
 */
@Controller
public class LastControler {
    @RequestMapping(value = "/home")
    public String showHomePage(Model model){

        model.addAttribute("name","spring-mvc");
        return "home";
    }
}

controller类

访问http://localhost:9100/home/这个网页就报404。
