下载安装 Idea ，支持付费正版，破解码自己去网上。

### 1 创建 Maven 项目 ###

![这里写图片描述][70 1]

这里 New 的路径选择到 maven 的 Home 目录：  
/Library/Java/JavaVirtualMachines/jdk1.8.0\_161.jdk/Contents/Home/

创建出来的maven 项目代码结构：

红色部分是之后我创建的。

*  recources文件夹，该文件夹一般用来存放一些资源文件，  
    webapp文件夹，用来存放web配置文件以及jsp页面等

这里Idea 提示你 Enable-Auto- Import，点击，可以在每次修改pom.xml后，自动的下载并导入jar包。

创建 `src/main/java` 目录，并且标记为 `Sources Root`

### 2 用 Maven 导入 jar 包 ###

Maven项目对象模型(POM)，可以通过一小段描述信息来管理项目的构建，报告和文档的软件项目管理工具。

配置你的 `pom.xml`，内容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

因为墙的关系，添加阿里云代理。

注意，dispatcher-servlet.xml 中的 base-package 是你创建的包名

运行，tomcat run spirngMvc 项目，需要先配置一下idea 的 tomcat 。
