對Spring Cloud Config有所瞭解的話，就會知道，Spring Cloud Config註冊到eureka後，其他服務會通過eureka找到Spring cloud config，並在Config服務中讀取自己的配置檔案。

此配置檔案可以通過GIT伺服器獲取、在所在應該的目錄中獲取、在所在伺服器中的資料夾中獲取。

2.application.yml配置

如果想將配置檔案放到專案中檔案，可以用一下配置

server:
  port: 2003

spring:
  application:
    name: xichuan-config-server
  profiles:
    active: native

  #本地測試使用
  context-path: /config

eureka:
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 1
    leaseExpirationDurationInSeconds: 2
    nonSecurePort: ${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:2001/eureka/

management:
  security:
    enabled: false
 

如果想讓配置檔案放到伺服器中某一目錄下，如/root/xichuan/configs目錄下，可以使用以下配置：

server:
  port: 2003

spring:
  application:
    name: xichuan-config-server
  profiles:
    active: native
##雲伺服器使用
  cloud:
    config:
      server:
        native:
          searchLocations:
            file:/root/xichuan/configs
    inetutils:
      ignoredInterfaces:
        - eth0

eureka:
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 1
    leaseExpirationDurationInSeconds: 2
    nonSecurePort: ${server.port}
  client:
    serviceUrl:
      defaultZone: http://localhost:2001/eureka/

management:
  security:
    enabled: false
 

3.啟動類添加註解

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableConfigServer
@EnableEurekaClient
public class XichuanConfigServerApplication {

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

我們可以看到eureka已經註冊了config-server服務

專案的啟動順序是：1.eureka，2.config-server，3.zuul(可選)，4.服務
