然后编辑web.xml文件

如果安装过STS插件的话, 直接按alt + 回车

![](/images/language/java/737076-20161111154423967-1614121837.png)

选择后就出来了, 然后改成如下
```xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
id="WebApp_ID" 
version="3.1">

  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationcontext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Map all requests to the DispatcherServlet for handling -->
    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
  
</web-app>

classpath:applicationcontext.xml 文件名可以修改, 无所谓

按照如图位置创建applicationcontext.xml文件

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

    <!-- 设置自动扫描的包 -->
    <context:component-scan base-package="cn.learn.*"></context:component-scan>
                                             要在src/main/java 下创建包为cn.learn, 为了方便就这么写了, 大神别喷我
    <!-- 开启自动注解支持 -->
    <mvc:annotation-driven />
    <!-- 定义静态资源位置 -->
    <mvc:resources location="/WEB-INF/static/" mapping="/static/**"></mvc:resources>
                             
    <!-- jsp视图处理 start -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 视图前缀 -->
        <property name="prefix" value="/WEB-INF/view/"></property>
        <!-- 视图后缀 -->
        <property name="suffix" value=".jsp"></property>
        <property name="viewClass"
            value="org.springframework.web.servlet.view.InternalResourceView" />
        <property name="order" value="1" />
    </bean>
    <!-- jsp视图处理 end -->

</beans>

然后变成这样的目录结构

 在cn.learn包下新建一个controller包(这一步不是必须的, 但是一般都要分开, 这东西看项目)

 然后在controller包下新建一个类 IndexController

package cn.learn.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/index")
public class IndexController {

    @RequestMapping("/helloword")
    public ModelAndView hellowordAction(){
        
        //直接返回到view目录下的 index目录下的helloword.jsp
        return new ModelAndView("index/helloword");
    }
}

新建文件 在 view/index/helloword.jsp

</head>
<body>
this is a helloword page
</body>
</html>

启动tomcat浏览器访问

http://localhost:8080/createspringmvc/index/helloword

应该注意到在applicationcontext.xml文件中配置过一个静态文件访问

 <mvc:resources location=”/WEB-INF/static/” mapping=”/static/**“></mvc:resources>

把web应用的所有 类似于js  css images 等, 不需要走框架的都放到这里

例如

写了一行   alert(1);

在浏览器中访问http://localhost:8080/createspringmvc/static/test.js

 如果把这个js在页面中引用的话

在helloword.jsp页面引用

再次访问http://localhost:8080/createspringmvc/index/helloword

 

 这样就完成springmvc的最基本的可以访问了
