-项目搭建)
1.搭建父工程创建统一的父工程yigou用来管理依赖及其版本注意是创建project而不是moudle填写坐标信息填写保存位置信息父工程不需要代码只是管理依赖因此我们不选择任何SpringCloud的依赖。然后将pom文件修改成我这个样子?xml version1.0 encodingUTF-8?projectxmlnshttp://maven.apache.org/POM/4.0.0xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0

yigou-api-gateway服务网关Zuul目前服务的结构如图所示截止到这里我们已经把基础服务搭建完毕为了便于开发统一配置中心ConfigServer我们留待以后添加。
