IDEA新建Spring项目

一、背景：

记得刚毕业是做web的，但是由于当时使用的是公司封装好的框架，再加上移动端兴起，开始转向移动端，一直到现在陆续有5年时间了，个人感觉到了一个瓶颈期，所以想试试后端发展。

二、环境：

IDEA：IntelliJ IDEA 2018.2.1 (Ultimate Edition)
JRE: 1.8.0_152-release-1248-b8 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.13.6

三、创建

1、创建新项目

2、选择maven

3、填写信息

GroupID：实际对应JAVA的包的结构，是main目录里java的目录结构。 ArtifactID：就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。
Version：版本号

后面继续点next，直到项目创建: image.png

四、配置项目结构

1、修改main目录结构

File -> Project Structure -> Modules 在main目录下新建两个文件夹 java、test，在两个目录中新建resources目录如下图

2、改变java、test文件属性

选择java文件夹，点击上部蓝色Sources图标
选择java文件夹中resources，点击上部灰色Resources图标
选择test文件夹，点击上部绿色Tests图标
选择test文件夹中resources，点击上部灰色Test Resources图标

完成后

五、配置Tomcat

创建Tomcat Server
创建 war exploded

六、运行测试

点击运行按钮 成功

七、添加必要的库

<properties>
        <springframework-version>4.3.14.RELEASE</springframework-version>
    </properties>
