label 是指 git 的分支

			
spring.cloud.config.label=mybranch
			
				

			
spring.cloud.config.server.git.basedir=api/configs
			
				

			
spring.application.name=config-server
spring.cloud.config.server.git.uri=https://netkiller:xxxxxx@github.com/xyz/microservices-configs.git
			
				

			
spring.application.name=config-server
spring.cloud.config.server.git.uri=https://github.com/xyz/microservices-configs.git
spring.cloud.config.server.git.username=netkiller
spring.cloud.config.server.git.password=password
			
				

创建本地仓库

			
mkdir ~/config
cd config
git init
git config --global user.email "neo.chen@live.com"
git config --global user.name "Neo Chen"
			
				

创建测试配置文件

			
# cat app-test.properties 
name=neo
age=10
			
				

提交配置文件

			
git add app-test.properties 
git commit -a
			
				

检查文件是否提交成功

			
[root@netkiller config]# git log
commit aee6c35bacf1740004e02f8ecdcf2fd322422405
Author: Neo Chen <neo.chen@live.com>
Date:   Thu Nov 2 14:18:48 2017 +0800

        new file:   app-test.properties
			
				

配置 Spring cloud config 服务器，修改 application.properties 文件

			
server.port=8888
#spring.cloud.config.server.git.uri=/opt/config
spring.cloud.config.server.git.uri= file://${user.home}/config
security.user.name=cfg
security.user.password=s3cr3t

## Spring cloud GIT Repository file
${user.home}/config/root-server.properties		
			
				

检验配置中心

			
[root@netkiller config]# curl http://cfg:test@localhost:8888/app-test.properties
age: 10
name: neo
			
				

载入本地配置文件 resources/shared/config-client-dev.yml

			
server:
  port: 8762
foo: foo version 1			
			
				

配置中心服务端 resources/application.yml 配置文件

			
server:
  port: 8769
spring:
  application:
    name: config-server
  profiles:
    active: native
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/shared			
			
				

测试配置文件

			
iMac:Java neo$ curl http://localhost:8769/config-client-dev.json
{"server":{"port":8762},"foo":"foo version 1"}
			
				

bootstrap.properties:

			
spring.application.name=project
spring.profiles.active=development
spring.cloud.config.uri=http://localhost:8888
spring.cloud.config.username=cfg
spring.cloud.config.password=s3cr3t
