Spring Cloud Config provides server and client-side support for externalized configuration in a distributed system.

Please change git url in application.properties, and you can check by http://localhost:8888/configserver/default

• please add dependency in your pom.xml.

    <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>

• Bootstrap Environment from server. In your bootstrap.properties add following code:

     spring.cloud.config.uri: http://localhost:8888/

• Verify your properties:

    $ curl http://localhost:8888/demo/master
    $ curl http://localhost:8888/demo/prod/master

• add @RefreshScope for your bean
• Change properties and push them to git repository
• Invoke 'curl -X POST http://localhost:8080/refresh' to refresh config

Config Server with Git adopts following rules to get configuration:

• properties or yml: "/{name}/{profile}/{label}": name is application name, profile is Spring profile name, and label is git branch or tag name.

  $ http http://localhost:8888/demo/default/master

• plain text: "/{name}/{profile}/{label}/{path}"

  $ curl http://localhost:8888/demo/default/master/demo.conf $ curl http://localhost:8888/demo/default/master/hibernate/demo.xml

1. application.properties: global properties for all apps
2. appname.properties: app properties
3. appname-profile.properties: app profile properties

• Add spring-cloud-starter-eureka dependency in your pom.xml:

 <dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-eureka</artifactId>
 </dependency>

• add property in the applicaton.properties

eureka.instance.prefer-ip-address=true
eureka.client.fetch-registry=false
