SpringCloud(Hoxton) Config--服务端配置与测试、配置文件读取规则

SpringCloud Config服务端配置

在GitHub新建一个名为springcloud-config的新Repository。

本地初始化一个仓库，将Repository克隆下来

git clone https://github.com/xxxx/springcloud-config.git

准备3个配置文件，并push到github：

新建config配置中心微服务cloud-config-center-3344

配置：application.yml

server:
  port: 3344

spring:
  application:
    name: cloud-config-center #注册进eureka的微服务名
  cloud:
    config:
      server:
        git:
          uri: [e-mail]:xxxx/springcloud-config.git
          search-paths:
            - springcloud-config #指定搜索目录
      label: master #读取分支

eureka:
  client:
    service-url:
      defaultZone: http://localhost:7001/eureka

启动类：

@SpringBootApplication
@EnableConfigServer
public class MainAppConfigCenter3344 {
    public static void main(String[] args) {
        SpringApplication.run(MainAppConfigCenter3344.class, args);
    }
}

测试：
启动eureka，再启动3344配置中心：

访问：localhost:3344/master/config-dev.yml

访问：localhost:3344/master/config-test.yml

访问：localhost:3344/master/config-prod.yml

配置文件读取规则

/{label}/{application}-{profile}.yml 示例：

• master分支

http://config-3344.com:3344/master/config-dev.yml
http://config-3344.com:3344/master/config-test.yml
http://config-3344.com:3344/master/config-prod.yml

• dev分支

http://config-3344.com:3344/dev/config-dev.yml
http://config-3344.com:3344/dev/config-test.yml
http://config-3344.com:3344/dev/config-prod.yml

/{application}-{profile}.yml 示例

http://config-3344.com:3344/config-dev.yml
http://config-3344.com:3344/config-test.yml
http://config-3344.com:3344/config-prod.yml
http://config-3344.com:3344/config-xxx.yml(不存在，返回  {}  )

默认找master分支，也可以在配置文件中指定label属性修改

/{application}/{profile}[/{label}] 示例

http://config-3344.com:3344/config/dev/master
http://config-3344.com:3344/config/test/master
http://config-3344.com:3344/config/prod/master

注意：该方式返回为JSON
