### 为什么要搭建父工程？ ###

> 主要是为了后边写的所有demo统一依赖版本  
> Maven中的dependencyManagement元素提供了一种管理依赖版本号的方式。在dependencyManagement元素中声明所依赖的jar包的版本号等信息，那么所有子项目再次引入此依赖jar包时则无需显式的列出版本号。Maven会沿着父子层级向上寻找拥有dependencyManagement 元素的项目，然后使用它指定的版本号

### 开始搭建项目 ###

1.  新建立maven项目  
    以IDEA为例，File->NEW -> Project![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NodWFpODYyNA_size_16_color_FFFFFF_t_70_pic_center]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NodWFpODYyNA_size_16_color_FFFFFF_t_70_pic_center 1]
2.  pom增加dependencyManagement如下

pom.xml如下

如果之前没有下载过依赖会报红，可以把dependencyManagement标签去掉；只保留dependencies，刷新去触发下载依赖；等下载完后再加上dependencyManagement标签即可；
