SpringCloud6-Config分布式配置中心-蒲公英云

SpringCloud6-Config分布式配置中心

springcloud版本: 【Finchley 版】

结构图

分布式配置中心
在这里插入图片描述
集中管理配置文件-提供了集中化的外部配置支持,配置服务器为各个微服务的环境提供了一个中心化的外部配置
动态配置
springcloud Config分为客户端和服务端(分布式配置中心,是一个独立的微服务应用)
推荐使用git管理版本信息

    config:
      server:
        git:

启动类

package com.zjy.config;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication { 
    public static void main(String[] args) { 
        SpringApplication.run(ConfigServerApplication.class, args);
    }
}

http://localhost:3344/application-dev.yml
http://localhost:3344/application-test.yml
http://localhost:3344/application-xxxxx.yml
第二种访问方式 http://localhost:3344/application/dev/master
第三种 http://localhost:3344/master/application-dev.yml

客户端配置

客户端配置上传到github
https://github.com/ai1045152332/springcloud-config/blob/master/cloud-config-client.yml
创建config-client项目

2.1 pom文件

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-client</artifactId>
</dependency>

2.2 bootstrap.yml系统级资源配置项,优先级高

spring:
  cloud:
    config:
      name: cloud-config-client # github上配置文件名
      profile: dev # 本次访问的配置项
      label: master
      uri: http://localhost:3344 # 连接server

application.yml (是用户级)

spring:
  application:
    name: cloud-config-client
