SpringCloud -创建统一的依赖管理
场景
spring cloud 为开发者提供了在分布式系统（配置管理，服务发现，熔断，路由，微代理，控制总线，一次性 token，全居琐，leader 选举，分布式 session，集群状态）中快速构建的工具，使用 spring cloud 的开发者可以快速的启动服务或构建应用、同时能够快速和云平台资源进行对接。

实现
在目录下新建一个目录hello-spring-cloud ,然后使用idea打开这个目录。
这个文件夹是用来放所有工程的，所以在idea上右击目录继续新建目录。
为统一的依赖管理项目取名字。
新建完成后再新建file--pom.xml
复制如下代码：
<?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"
