08.2 SpringCloud Config服务端配置

SpringCloud Config服务端配置

1. Git托管配置文件

本文使用Github私有仓库来实现,创建过程略(配置文件为敏感数据,尽量使用私有仓库模式)

创建完成后添加文件 application.yml文件

spring:
  profiles:
    active:
      - dev
---
spring:
  #开发环境
  profiles: dev
  application:
    name: microservicecloud-config-atguigu-dev
---
spring:
  #测试环境
  profiles: test
  application:
    name: microservicecloud-config-atguigu-test
#请保存为UTF-8格式

2. 服务端配置

2.1 新建Module模块microservicecloud-config-3344

它即为Cloud的配置中心模块

2.2 pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.3 yml文件

server:
  port: 3344
spring:
  application:
    name: microservicecloud-config
  cloud:
    config:
      server:
        git:
          #GitHub上面的git仓库名字
          uri: git@github.com:lujiahao0708/microservicecloud-config.git

2.4 主启动类

@SpringBootApplication
@EnableConfigServer
public class Config3344Application {
    public static void main(String[] args) {
        SpringApplication.run(Config3344Application.class, args);
    }
}

2.5 hosts文件增加

127.0.0.1  config-3344.com

2.6 验证

启动config-3344服务,访问url查看结果

前两个分别为dev环境和test环境,最后一个为不存在的环境

3. 配置读取规则

/{application}-{profile}.yml
    http://config-3344.com:3344/application-dev.yml
    http://config-3344.com:3344/application-test.yml
    http://config-3344.com:3344/application-xxx.yml(不存在的配置)
/{application}/{profile}[/{label}]
    http://config-3344.com:3344/application/dev/master
    http://config-3344.com:3344/application/test/master
    http://config-3344.com:3344/application/xxx/master
/{label}/{application}-{profile}.yml
    http://config-3344.com:3344/master/application-dev.yml
    http://config-3344.com:3344/master/application-test.yml
