#                   SpringCloud-config(服务端，客户端的环境搭建) #

注明：此项目为本人学习尚硅谷老师的教学视频然后整理核心的配置文件，所有的项目均在以下地址下载。  
[https://github.com/xwbGithub/microservicecloud][https_github.com_xwbGithub_microservicecloud]下载

本项目请参考microservicecloud-config-3344（作为config配置中心），microservicecloud-config（作为客户端）

## 服务端的搭建 ##

新建module模块microservicecloud-config-3344(作为cloud的配置中心模块)

### pom核心文件 ###

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

### yml文件 ###

server:
      port: 3344
    spring:
      application:
        name: microservicecloud-config
      cloud:
        config:
          server:
            git:
              #username:  xxxx
              #password: xxxx
              uri: https://github.com/xwbGithub/microservicecloud-config.git #github上的原始地址

### 主启动类添加EnableConfigServer注解 ###

@SpringBootApplication
    @EnableConfigServer
    public class Config_3344_StartSpringCloudApp {
        public static void main(String[] args) {
            SpringApplication.run(Config_3344_StartSpringCloudApp.class, args);
        }
    }

### 修改主机映射 ###

Windows对应的位置是：C:\\Windows\\System32\\drivers\\etc\\hosts

Linux对应的是：/etc/hosts

127.0.0.1 config-3344.com

### 测试 ###

启动微服务3344

访问[http://config-3344.com:3344/application-dev.yml][http_config-3344.com_3344_application-dev.yml]

![70][]

### 本地config搭建 ###

在本地的项目microservicecloud-config下创建microservicecloud-config-client.yml文件

microservicecloud-config-client.yml内容如下：

### yml ###

spring:
      profiles:
        active:
          - dev
    ---
    server:
      port: 8201
    spring:
      profile: dev
      application:
          name: microservicecloud-config-client
    eureka:
      client:
        service-url:
          defaultZone: http://eureka-dev.com:7001/eureka/
    ---
    server:
      port: 8202
    spring:
      profiles: test
      application:
        name:  microservicecloud-config-client
    eureka:
      client:
        service-url:
            defaultZone:  http://eureka-test.com:7001/eureka/

然后上传到github上本人地址为[https://github.com/xwbGithub/microservicecloud-config][https_github.com_xwbGithub_microservicecloud-config]

### b客户端的搭建 ###

创建客户端modulemicroservicecloud-config-client-3355

### pom ###

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

Application.ym(是用户级的配置资源项)

Bootstrap.yml(是系统级的，优先级更高)

### 创建bootstrap.yml文件 ###

spring:
      cloud:
        config:
          name: microservicecloud-config-client # 需要从github上读取资源名称 注意没有yml
          profile: dev # 本次访问的配置项
          label:  master
          uri:  http://config-3344.com:3344 # 本资源微服务启动后先去找3344号服务，通过SpringCloudConfig获取Github的服务地址

# #

### application.yml文件 ###

spring:
      application:
        name:  microservicecloud-config-client

host下添加映射文件

127.0.0.1 client-config.com

新建controller类ConfigClientRest

package com.atguigu.springcloud.rest;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    @RestController
    public class ConfigClientRest
    {
       @Value("${spring.application.name}")
       private String applicationName;
       @Value("${eureka.client.service-url.defaultZone}")
       private String eurekaServers;
       @Value("${server.port}")
       private String port;
       @RequestMapping("/config")
       public String getConfig() {
          String str = "applicationName: " + applicationName + "\t eurekaServers:" + eurekaServers + "\t port: " + port;
          System.out.println("******str: " + str);
          return "applicationName: " + applicationName + "\t eurekaServers:" + eurekaServers + "\t port: " + port;
       }
    }

### 启动主动类 ###

@SpringBootApplication
    public class ConfigClient_3355_StartSpringCloudApp{
       public static void main(String[] args) {
          SpringApplication.run(ConfigClient_3355_StartSpringCloudApp.class, args);
       }
    }

## 测试 ##

启动config的服务器3344

然后启动3355作为client准备访问

测试1:

切换bootstrap.yml的访问配置项

**profile：dev**(切换bootstrap.yml的访问配置项)

1、dev默认在github上对应的端口就是8201

2、[http://client-config.com:8201/config][http_client-config.com_8201_config]

![70 1][]

**Profile: test**

1、test默认在github上对应的端口就是8202

2、[http://client-config.com:8202/config][http_client-config.com_8202_config]
