一、项目创建：

1、创建一个Javaweb项目并且配置好tomcat等

（之前做过 此步省略）

 

2、在setting中引入MAVEN

 注意：

MAVEN 的版本不能早于编辑器的版本否则会报错。

 

3、创建项目结构

二、代码编写：

修改pom.xml文件，导入需要的包：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
