我们现在搞个实例来演示下，eureka整合config以及服务器提供者整合config，这样大伙可以举一反一，方便理解；

首先是eureka整合config

我们先搞个配置文件到git；

eureka_config.yml

spring:
  profiles:
    active:
    - dev
---
server:
  port: 2004
  context-path: /
spring:
  profiles: dev
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false     #false 由于该应用为注册中心，所以设置为false,代表不向注册中心注册自己。
    fetch-registry: false     #false 由于注册中心的职责就是维护服务实例，它并不需要去检索服务，所以也设置为false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/       #设置与Eureka注册中心交互的地址，查询服务和注册服务用到       #设置与Eureka注册中心交互的地址，查询服务和注册服务用到
---
server:
  port: 2005
  context-path: /
spring:
  profiles: test
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false     #false 由于该应用为注册中心，所以设置为false,代表不向注册中心注册自己。
    fetch-registry: false     #false 由于注册中心的职责就是维护服务实例，它并不需要去检索服务，所以也设置为false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/       #设置与Eureka注册中心交互的地址，查询服务和注册服务用到       #设置与Eureka注册中心交互的地址，查询服务和注册服务用到

新建module microservice-eureka-server-config-2004

pom.xml:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>

bootstrap.yml

spring:
  application:
    name: microservice-eureka-server-config
  cloud:
    config:
      name: eureka_config
      uri: http://configserver.javaxl.com:4001  # 配置configserver地址
      profile: dev  # 级别
      label: master  # 分支 git中 默认master

application.yml

spring:
  application:
    name: microservice-eureka-server-config

启动类：

package com.javaxl.microserviceeurekaserverconfig2004;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class MicroserviceEurekaServerConfig2004Application {

    public static void main(String[] args) {
        SpringApplication.run(MicroserviceEurekaServerConfig2004Application.class, args);
    }

}

我们启动 microservice-config-server-4001

再启动 microservice-eureka-server-config-2004

测试连接

http://localhost:2004/ 或

http://eureka2001.javaxl.com:2004/

说明成功读取远程Git配置，然后eureka启动OK；

然后我们就是把服务提供者和config整合，把服务提供者注册到eureka；

我们搞个配置provider_config.yml，push到远程GIT；

其他类文件从 原先的服务提供者里直接复制一份即可，这里不贴了；

启动下这个项目；

说明成功注册到服务注册中心了；
