远程仓库受网络影响，可以从本地(配置中心)
注册中心与配置中心合并在一起，可能导致页面没有样式，所以分开来。

注册中心
spring.application.name=config-registration
server.port=9000
eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class ConfigRegistrationApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigRegistrationApplication.class, args);
}
}
配置中心
spring.application.name=config-server
server.port=9500
eureka.client.service-url.defaultZone=http://localhost:9000/eureka
# 连接到远程仓库
spring.cloud.config.server.git.uri=https://gitee.com/baozi-baozi/cloud-config.git

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.config.server.EnableConfigServer;
@SpringBootApplication
@EnableConfigServer // 开启配置中心
//@EnableDiscoveryClient // 这个可以省略
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
访问规则：
1. application：上面文件中的config-clients
2. profile：上面文件中的dev，如果没有就是default
3. labei：就是分支，不写默认为master
4. /application/profile[/label]
http://localhost:9500/config-clients/default
http://localhost:9500/config-clients/default/master
http://localhost:9500/config-clients/dev
http://localhost:9500/config-clients/dev/master
5. /application-profile.[yml | properties | json ]
http://localhost:9500/config-clients-default.properties
http://localhost:9500/config-clients-default.yml
http://localhost:9500/config-clients-default.json
http://localhost:9500/config-clients-dev.properties
http://localhost:9500/config-clients-dev.yml
http://localhost:9500/config-clients-dev.json
6. /label/application-profile.[yml | properties | json ]
在前一个基础上加上分支。
配置客户端

# 配置文件对应的application部分, 同时也是spring.application.name的名字
spring.application.name=config-clients
server.port=10000
# 可以写在配置中心的配置文件中
eureka.client.service-url.defaultZone=http://localhost:9000/eureka
# config-server的url, 可以写多个。
# spring.cloud.config.uri=http://localhost:9500/
# 可以用服务发现的方式代替写多个uri
spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.service-id=config-server
# profile部分
#spring.cloud.config.profile=default
spring.cloud.config.profile=dev
# label部分
spring.cloud.config.label=master
