1.为什么要Spring Cloud Config
如何高效地管理配置成为我们必须解决的问题。本节来讨论如何使用Spring Cloud Config管理配置。Spring Cloud Config为分布式系统外部化配置提供了服务器端和客户端的支持，它包括Config Server和Config Client两部分。由于Config Server和Config Client都实现了对Spring Environment和PropertySource抽象的映射，因此，Spring Cloud Config非常适合Spring应用程序，当然也可与任何其他语言编写的应用程序配合使用。
1.直接从本地拉取

加注解：@EnableConfigServer
写配置：
spring:
cloud:
config:
server:
native:
search-locations: classpath:/shared
profiles:
active: native
application:
name: config-server
server:
port: 8769
eureka:
client:
register-with-eureka: false
fetch-registry: false
因为是本地:在resources下新建目录shared 下新建文件config-client-dev.yml

Config Client:

bootstrap.yml
spring:
application:
name: config-client
cloud:
config:
uri: http://localhost:8769
fail-fast: false
profiles:
active: dev
controller:
浏览器输入http://localhost:8762/nihao
foo version1
2.实现从远程仓库读取配置文件(git仓库)
修改config-server下的application.yml文件,私人仓库需要账号密码
server:
port: 8796
spring:
application:
name: config-server
cloud:
config:
server:
git:
# Git仓库地址
uri: https://gitee.com/ssml/serverConfig.git
# Git仓库账号
username: [email protected]
# Git仓库密码
password: ******
# search-paths: SpringCloudConfig/shared
eureka:
client:
register-with-eureka: false
fetch-registry: false
浏览器输入http://localhost:8762/nihao
foo version1 僧产环境
3.建立一个高可用的configServer
只须将多个Config Server节点注册到Eureka Server上，即可实现Config Server的高可用。
1.引入eureka Server
2.修改configServer
2.1添加依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>2.2添加注解
3.1.修改configClient
3.1添加依赖
3.2添加注解
foo version1
