Spring Cloud Config 远程仓库

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

bootstrap.properties

# 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

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class ConfigClientsApplication {

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

}
