1.简介
SpringCloud Config 服务配置中心，将所有的服务的配置文件放到本地或远程仓库，配置中心负责读取仓库的配置文件，其他服务向被指中心读取配置文件。
2.项目目录
3. 服务发现中心（eureka-server）

3.2 bootstrap.yml 配置文件
bootstrap 加载优先于 applicaton。bootstrap 主要用于从额外的资源来加载配置信息，还可以在本地外部配置文件中解密属性。这两个上下文共用一个环境，它是任何Spring应用程序的外部属性的来源。bootstrap 里面的属性会优先加载，它们默认也不能被本地相同配置覆盖。
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false #禁止自己当做服务注册
fetch-registry: false #屏蔽注册信息
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
spring:
application:
name: eurka-server
3.3 EurekaServerApplication 启动类
@SpringBootApplication
//开启eureka注册发现
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class,args);
}
}
访问locahost:8761
3. 服务配置中心（config-server）
项目目录
在这里笔者使用的是远程仓库Gitee，所以笔者先配置了Gitee所需的仓库
新建仓库
新建文件夹
3.1 pom文件

3.2 bootstrap.yml 配置文件
spring:
application:
name: config-server
cloud:
config:
server:
git:
uri: https://gitee.com/he12345600/springcloudconfig
default-label: master
search-paths: config
server:
port: 8769
eureka:
client:
serviceUrl:
defautlZone: http://localhost:8761/eureka/
3.3 ConfigServerApplication 启动类
@SpringBootApplication
@EnableConfigServer
//开启向eureka注册功能
@EnableEurekaClient
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
继续访问localhost:8761
3. 服务（config-client）
项目结构
在这里回到Gitee中config文件夹下创建文件eureka-client.yml
server:
port: 8762
eureka:
instance:
hostname: localhost
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/

3.2 bootstrap.yml 配置文件
spring:
application:
name: eureka-client # 当前服务应用名
cloud:
config:
label: master
discovery:
enabled: true # 开启config服务发现与注册
serviceId: config-server # 配置中心应用名
3.3 ConfigClientApplication 启动类
@SpringBootApplication
@EnableEurekaClient
public class ConfigClientApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigClientApplication.class,args);
}
}
3.4 IndexController 控制器
@RestController
public class IndexController {
@RequestMapping("/")
public String index(){
return "this is index()";
}
}
4.测试
访问locahost:8761
访问localhost:8762
