# server端 #

## 1.pom中添加依赖 ##

<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-config-server</artifactId>
    			<version>2.0.1.RELEASE</version>
    		</dependency>

## 2.启动类 ##

添加注解@EnableConfigServer

## 3.配置文件 ##

application.yml配置文件

server:
      port: 5000
    spring:
      application:
        name: config-server
      cloud:
        config:
          server:
            git:
            ##定义去拉取本地配置的地址
              uri: D:\\code\\item\\springcloud\\day02_config\\config-server\\src\\main\\resources\\configs
            ##远程拉取配置文件的配置
            ##uri: https://github.com/936981178/springcloudconfig.git     # 配置git仓库的地址
            ##search-paths: config-repo  # git仓库地址下的相对地址，可以配置多个，用,分割。
            ##username:                  # git仓库的账号
            ##password:                  # git仓库的密码
    management:
      endpoints:
        web:
          exposure:
            include: "*"

配置eurekaserver文件  
一般都有三个环境的配置文件  
![在这里插入图片描述][20200210114819388.png]\`\`\`

spring:
      application:
        name: eureka-peer
    
    server:
      port: 10000
    
    eureka:
      instance:
        hostname: dev
        instance-id: dev
      client:
        fetch-registry: false
        register-with-eureka: false
        service-url:
          defaultZone: http://localhost:10000/eureka/
      server:
        wait-time-in-ms-when-sync-empty: 0
        enable-self-preservation: true
        peer-eureka-nodes-update-interval-ms: 10000

## 4.git初始化 ##

打开git初始化：  
git init  
git add .  
git commit -m “frist commit”

启动,访问http://localhost:5000/eurekaserver/dev  
![在这里插入图片描述][20200210115207801.png]  
可读取到配置文件内容

# eureka从配置中心拉取配置(config\_client端) #

## 1.pom依赖 ##

<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-config-client</artifactId>
    			<version>2.0.1.RELEASE</version>
    		</dependency>

## 2.配置文件 ##

config的相关配置是要先于application.properties的，所以需要使用bootstrap.yml,其配置文件的加载先于application.properties。

bootstrap,yml

server:
      port: 10000
    
    spring:
      application:
        ##config服务configs的文件名对应
        name: eurekaserver
      cloud:
        config:
          name: eurekaserver
          uri : http://localhost:5000/
      profiles:
        ##config服务configs中对应文件名后面的环境
        active: dev

启动访问http://localhost:10000/  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQyODE1MTIy_size_16_color_FFFFFF_t_70 1]

# 测试 #

同eureka-server一样,将上次的eureka-client交给config配置中心管理

## 配置文件 ##

在config服务中新建helloclient-dev.yml配置文件

name: mcw
    age : 22
    
    eureka:
      client:
        service-url:
          defaultZone: http://127.0.0.1:10000/eureka/

将配置文件添加到git中

git add helloclient-dev.yml
    git commit -m "helloclient commit"

在eureka-client服务添加测试代码

public class Teacher {
    
        private String  name;
        private int age;
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
    }

@RestController
    public class HelloEurekaController {
    
        @Value("${name}")
        private String name;
    
        @Value("${age}")
        private int age;
    
        @GetMapping("")
        public Object index(){
            Teacher teacher = new Teacher();
            teacher.setAge(this.age);
            teacher.setName(this.name);
            return teacher;
        }
        
    }

启动访问http://localhost:8001/
