在微服务架构中，为解决各服务版本不一致的问题，文章提出了创建自定义parent项目的方案。通过定义`custom-parent`，集中管理SpringBoot、SpringCloud等依赖版本，以及JDK和其他jar包版本，以此作为所有微服务的父项目，达到统一标准和简化配置的目的。

解决的问题：

问题：
当项目为微服务架构时，每个微服务均需定义基本标准，如：SpringBoot、SpringCloud等版本、jdk版本、其它jar包版本等，标准及维护比较困难。

方案：
自定义parent项目，规范标准、基本引用，自定义parent项目作为所有微服务的parent，统一标准、减少配置。

1、custom-parent

1.1、新建maven项目，pom.xml文件如下

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

1.2、编译安装parent项目

maven clean compile install

2、微服务使用

2.1、新建微服务，pom.xml如下

使用 <parent> 引用自定义的parent
基于parent做二次开发，且可以直接引用parent定义好的包
