跟我学SpringCloud | 第七篇：Spring Cloud Config 配置中心高可用和refresh

SpringCloud系列教程 | 第七篇：Spring Cloud Config 配置中心高可用和refresh Springboot: 2.1.6.RELEASE SpringCloud: Greenwich.SR1 如无特殊说明，本系列教程全采用以上版本 1. 引言 上一篇我们聊了Spring Cloud Config 配置中心，并且和Github做了集成，我们的Server端是单机版的，任何单机版的服务都只能使用与测试环境或者自己做Demo测试， 生产环境严禁使用单机服务 ，配置中心在整个微服务体系中都是及其重要的一个节点，尤其是在DevOps中自动扩容，如果配置中心宕机，那么所有的自动扩容都会失败。 所以这一篇我们聊聊配置中心的高可用，说到高可用，在springcloud体系中，是有注册中心的，那么，我们的配置中心也是一个服务，可不可以使用Eureka做服务的注册与发现呢？ 答案是肯定的。 2. Serve端 我们将上一篇的Serve端Copy到新的目录中，增加Eureka-client的依赖，使得Config-Serve可以注册到Eureka上。 2.1 pom.xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi=

问题 I am working on Spring cloud contract documentation and I have seen a comment in dependency from Spring cloud documentation and would like to know what exactly is this <!-- If you're adding this dependency explicitly you have to add it *BEFORE* the Release Train BOM--> 回答1: Please read the docs: https://projects.spring.io/spring-cloud/ .
