## 一、新建一个Java工程（按以下截图操作即可） ##

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 2][]

**创建完成如下图所示**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 3][]

## 二、添加SpringMVC ##

### 1、右击工程名字（再点击Add Framwork Support） ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 4][]

### 2、点击添加SpringMVC（会自动下载SpringMVC所需要的包） ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 5][]

**下载过程如下图：**

![20210215133846412.png][]

**都添加成功之后应该会多出一个lib文件夹（用来存放SpringMVC的依赖包）和web文件夹**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 6][]

### 3、点击idea的File=>选择项目结构（Project Structure） ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 7][]

*  **3.1点击Artifacts=>Fix(在右下角)**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 8][]

*  **3.2 add以下两个依赖**

![20210215134455761.png][]

*  **3.3 都添加完之后：Fix会消失，最后一定要点击Apply然后点击ok即可**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 9][]

*  **3.4 添加成功后：项目目录会多出两个配置文件**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 10][]

## 三、添加Tomcat ##

### 1、点击下图中的Add Configuration ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 11][]

### 2、点击+号，添加Tomcat local ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 12][]

### 3、依次点击Fix=>apply=>ok ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 13][]

### 4、测试Web项目是否能部署到Tomcat上（点击运行） ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 14][]

若成功浏览器会自动弹出如下页面（表示成功）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 15][]

## 四、SpringMVC文件配置 ##

### 1、web.xml修改（将\*.form换为/） ###

### ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 16][] ###

### 2、在WEB-INF下新建一个文件夹，并创建一个success.jsp文件 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 17][]

success.jsp内容如下

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Title</title>
    </head>
    <body>
    成功！
    </body>
    </html>

### 3、控制器编写（在src目录下新建一个java文件，需要包名） ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 18][]

MyFirstController.java文件编写如下

@Controller
    public class MyFirstController {
        //访问路径
        @RequestMapping("/hello")
        public String myFirstRequest(){
            System.out.println("请求收到了...正在处理中");
            //视图解析器
    //        <property name="prefix" value="/WEB-INF/pages/"></property>  前缀
    //        <property name="suffix" value=".jsp"></property>             后缀
            return "success";            //实际上是 "/WEB-INF/pages/success.jsp"
        }
    }

### 4、dispatcher-servlet.xml配置 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 19][]

配置代码如下：

<?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.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
        <context:component-scan base-package="com.atguigu.controller"></context:component-scan>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/pages/"></property>
            <property name="suffix" value=".jsp"></property>
        </bean>
    </beans>

## 五、测试第一个SpringMVC ##

### 1、修改index.jsp ###

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
      <head>
        <title>$Title$</title>
      </head>
      <body>
      <a href="hello">跳转到success页面</a>
      </body>
    </html>

### 2、点击运行 ###

![20210215141654864.png][]

### 3、在弹出的页面中点击跳转到success页面 ###

![20210215141813227.png][]

### 4、跳转成功表示SpringMVC工程创建成功了 ###
