springcloud版本: 【Finchley 版】

结构图

分布式配置中心

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

管理版本信息

1. 新建github仓库
   
   仓库地址: [email protected]:ai1045152332/springcloud-config.git

Mac下git 相关问题:

2. 克隆到本地
git clone ssh地址
3. 上传

内容:

spring:
  profiles:
    active:
    - dev

spring:
  profiles: dev
  application:
    name: eureka-client-user-dev

spring:
  profiles: test
  application:
    name: eureka-client-user-test
# 保存为UTF-8

上传的命令

git status
git add .
git commit -m ""
git push origin master

yml

server:
  port: 3344
spring:
  application:
    name: eureka-client-config-server
  cloud:
    config:
      server:
        git:
          uri: https://github.com/ai1045152332/springcloud-config.git
          username: ai1045152332
          password: ********
          # 缓存位置
          basedir: /Users/zhaojianyu/IdeaProjects/springcloud-parent/eureka-client-config/src/main/resources/file

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);
    }
}

访问方式

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

客户端配置

1. 客户端配置上传到github
   https://github.com/ai1045152332/springcloud-config/blob/master/cloud-config-client.yml
2. 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

3. 接口

/**
 * 描述:
 * 配置客户端rest访问配置
 *
 * @author zhaojianyu
 * @create 2018-12-21 8:49 PM
 */
@RestController
public class ConfigClientRest {
    @Value("${spring.application.name}")
    private String applicationName;

    @Value("${eureka.client.service-url.defaultZone}")
    private String eurekaServer;

    @Value("${server.port}")
    private String port;

    @RequestMapping("/config")
    public String getConfig(){
    	//通过3344 server获取配置信息
        return "application:"+applicationName+"<br/>"+
                "eurekaServer:"+eurekaServer+"<br/>"+
                "port:"+port+"<br/>";
    }
}

启动类无特殊改动
4. 两种访问


并且已经注册到eureka server中

给server配置密码
