Spring Cloud 搭建微服务 — 统一依赖管理

概述

Spring Cloud 项目都是基于 Spring Boot 进行开发，目前大部分公司都会使用 Maven 来构建管理项目，所以在实际开发中，一般都会创建一个 Maven 依赖管理项目作为 Parent 项目，这样的话可以很方便对项目中的 Jar 包版本进行统一管理。

 
 

创建统一依赖管理工程

创建目录 hello-spring-cloud-dependencies，并在该目录下创建 pom.xml

完整的 pom.xml 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">
