项目目的：

由于导入的项目没有达到预期的效果，决定自己根据原有代码重新搭建项目。

  • 开始创建项目，项目父工程

　父工程结构，接下来添加依赖。

  • 项目依赖

  • 导入sql建表

  •  子项目——entity

  • 子项目——dao

　

需要引入entity的包，否则报错，引入方法：dao子项目的pom.xml右键==》Maven==》add Dependency 输入坐标

  • 　添加ApplicationContext-dao、SqlMapConfig.xml配置文件

 ApplicationContext-dao:

  • 子项目——工具类utils

  

  • 子项目——service层

 

  •  添加ApplicationContext-service配置文件

  • 子项目——web

 注意这里打包方式要选择war，以上的子项目打包方式选择jar。

  •  添加WEB-INF文件夹、web.xml文件

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