二、声明war打包方式并创建web项目目录结构
2.1 创建web项目结构
有关于Maven不了解的小伙伴不要灰心，请参考Maven教程
声明war包打包方式，即在pom.xml文件中加入一行标签
，随后创建web项目目录结构！war
| 手动构建web项目结构 |
|---|
| 基于main目录下创建webapp文件夹 |

三、引入tomact服务器并设置
关于Tomact服务的引入，需要我们手动添加tomact服务
添加tomact服务后，如果对tomact服务器在IDEA中的开发流程不熟悉的小伙伴，不要灰心。请参考tomact服务器基础和开发步骤即可，此文章中详细讲到了关于tomact的各种知识点！
