1, 新建專案，選擇Maven，如圖一次選擇，最後點選Next

2， 輸入GroupId和ArtifactId，點選Next

3，根據需要選擇自定義maven配置，點選Next。（①可以直接跳過）

4，根據需要修改專案名稱（一般不用修改），點選Finish。（①可以直接跳過）

6，修改pom.xml，新增依賴包

<dependencies>

  <dependency>

    <groupId>org.springframework</groupId>

    <artifactId>spring-webmvc</artifactId>
 

    <version>4.3.5.RELEASE</version>

  </dependency>

</dependencies>

package com.blueStarWei.controller;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;
 

import org.springframework.web.bind.annotation.RestController;

@RestController

@RequestMapping("/hello")

public class HelloWorld {

    @RequestMapping("/say/{name}")

    public String say(@PathVariable String name){

        return "Hello World, "+name;

    }

}

9，配置applicationContext.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

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

       xmlns:context="http://www.springframework.org/schema/context"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd

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

  <context:component-scan base-package="com.blueStarWei.*" />

  <bean id="viewResolver"

        class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <property name="prefix" value="/WEB-INF/jsp/" />

    <property name="suffix" value=".jsp"/>

  </bean>

</beans>

10，配置web.xml

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

<web-app version="2.4"

         xmlns="http://java.sun.com/xml/ns/j2ee"

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

         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <!--  DispatcherServlet預設使用WebApplicationContext作為上下文，

      Spring預設配置檔案為“/WEB-INF/[servlet名字]-servlet.xml”

   -->

  <servlet>

    <servlet-name>springmvc</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>springmvc</servlet-name>

    <url-pattern>/</url-pattern>

  </servlet-mapping>

</web-app>

11，建立springmvc-servlet.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

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

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package="com.blueStarWei.*" />

    <mvc:annotation-driven/>

</beans>

12, 配置tomcat.（⑦和⑧可以跳過）

13，專案配置完成，可以啟動伺服器，（使用瀏覽器活postman等）進行訪問。
