创建配置文件，上传至Github
```yaml
server:
port: 8070
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
applicatiom:
name: configclient
```
**创建ConfigServer，新建maven工程**，pom.xml
```yaml
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
</dependencies>
```
创建配置文件 application.yml
```yaml
server:
port: 8888
spring:
application:
name: configserver
cloud:
config:
server:
git:
uri: https://github.com/hnust-xijing/springcloud1.git
search-paths: config
username: root
password: root
label: master
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
```
创建启动类
```java
package com.shuang;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class,args);
}
}
```
**创建Config Client**
创建maven工程，pom.xml
```yaml
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
</dependencies>
```
创建bootstrap.yml
```yaml
spring:
cloud:
config:
name: configclient
label: master
discovery:
enabled: true
service-id: configserver
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka/
```
注解声明：
spring.cloud.config.name:当前服务注册在Eureka server上的名称，与远程仓库配置文件名对应。
spring.cloud.config.labal:Git Repository的分支。
spring.cloud.config.discovery.enable:是否开启Config服务发现支持。
spring.cloud.config.discovery.service-id:配置中心在Eureka Server上注册的名称。
创建启动类
```java
package com.shuang;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ConfigClientApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigClientApplication.class,args);
}
}
```
创建Handler
```java
package com.shuang.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/hello")
public class HelloHandler {
@Value("${server.port}")
private String port;
@GetMapping("/index")
public String index(){
return this.port;
}
}
```
依次启动：
