创建Git仓库
项目基本信息从Git中拉取，首先在gitee或者github中创建仓库，命名为learning-online
初始化Git到本地
使用IDEA创建项目，选择Get from VCS，填写仓库的URL
创建.gitignore文件，填入如下内容：
logs/
HELP.md
target/
!.mvn/wrapper/maven-wrapper.jar
!**/src/main/**/target/
!**/src/test/**/target/
### STS ###
.apt_generated
.classpath
.factorypath
.project
.settings
.springBeans
.sts4-cache
### IntelliJ IDEA ###
.idea
*.iws
*.iml
*.ipr
### NetBeans ###
/nbproject/private/
/nbbuild/
/dist/
/nbdist/
/.nb-gradle/
build/
!**/src/main/**/build/
!**/src/test/**/build/
### VS Code ###
.vscode/
### Mac OS ###
.DS_Store
|
使用IDEA创建分支dev01，并切换到该分支
项目工程结构
提供服务的模块learning-online-contet的依赖继承关系如下，其他所有提供服务的模块都将按照如下关系创建
创建父工程
右键learning-online选择New下面的Module；填入learning-online-parent，注意其真实目录地址在learning-online目录下。
父工程只负责Maven版本控制，只保留pom.xml文件，内容如下：
pom.xml<?xml version="1.0" encoding="UTF-8"?>

创建基础模块
创建新模块learning-online-base，其Parent为learning-online-parent但其目录位置在learning-online下，创建完成后其pom.xml的内容如下：
pom.xml<?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"

创建内容管理模块
创建新模块**learning-online-content**，其Parent为learning-online-parent但其目录位置在learning-online下，目录结构如下：
learning-online
├── learning-online-base
├── learning-online-content
└── learning-online-parent
|
创建内容管理接口工程
创建步骤同上，创创建新模块learning-online-content-api，其Parent为learning-online-content
创建内容管理服务工程
创建步骤同上，创创建新模块learning-online-content-service，其Parent为learning-online-content
创建内容管理模块工程
创建步骤同上，创创建新模块learning-online-content-model，其Parent为learning-online-content
最终的目录结构
工程都是空的，只是初始化项目结构
learning-online
├── learning-online-base
├── learning-online-content
│ ├── learning-online-content-api
│ ├── learning-online-content-service
│ └── learning-online-content-model
└── learning-online-parent
