本Demo演示了Config服务端的搭建，以及客户端如何通过Config服务端获取配置文件。
源码:https://github.com/seepine/spring-cloud-demo
模块介绍
spring-cloud-demo-02-config模块分为两个子模块，分别为Config-Server(Config服务端)和Config-Client(Config客户端)。
一、搭建Config服务端
1.Config-Server
1.1 添加依赖

| <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
|
1.2 在启动类上添加注解@EnableConfigServer

@SpringBootApplication
public class SpringCloudDemo02ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringCloudDemo02ConfigServerApplication.class, args);
}
}

git:
uri: https://github.com/seepine/spring-cloud-demo-config
server:
port: 10000
|
1.4 创建git配置文件仓库（可参考https://github.com/seepine/spring-cloud-demo-config）
创建文件名为config-client-dev.yml

1.5 启动ConfigServer并验证
输入地址及文件名：http://127.0.0.1:10000/config-client-dev.yml
2.Config-Client
2.1 添加依赖

@Component
@ConfigurationProperties(prefix = "user")
public class UserConfig {
private String username;
private String password;
}

public class ApiController {
private User user;
private UserConfig userConfig;
@GetMapping("/user")
public Object getUser() {
return user;
}
@GetMapping("/user/config")
public Object getUserConfig() {
return userConfig;
}
}

2.5 分别测试两个接口
3.整合Eureka
3.1 Config-Server与Config-Client添加依赖

| eureka:
instance:
hostname: localhost
client:
service-url:
defaultZone: http://seepine:123456@${eureka.instance.hostname}:8761/eureka/
