IDEA2017下搭建SSM框架

2018-02-28 本文已影响0人 Hank_谢旱

一准备工作

安装JDK，本示例采用1.7版本;
安装Tomcat;
安装MySql;
安装IEDA2017；

二步骤

1.首先使用idea新建一个Maven webapp项目

新建.png

初步配置.png

选择maven路径.png

新建工程.png

点击Finish，第一次搭建可能会很慢，甚至可能需要VPN才能搭建成功

2.目录结构

目录结构1.png

目录结构2.png

主要是XML文件都放在resources下

这里的目录建好之后还需要设置一下，让idea识别目录作用，选择File-Project Structure

三配置文件
