Let's implement an application main class that has more special annotations. Here, @SpringBootApplication will pull all the default and required configurations, and another annotation, @EnableConfigServer, will turn our application into a configuration server:

package com.dineshonjava.cloudconfigapp; 
 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.cloud.config.server.EnableConfigServer; 
 
@SpringBootApplication 
@EnableConfigServer 
public class CloudConfigApplication { 
   public static void main(String[] args) { 
         SpringApplication.run(CloudConfigApplication.class, args); 
   } 
} 

As you can, this enables the application as a configuration server. But by default, the server port will be 8080. We can change this default port configuration, and we have to provide the Git URI, which provides our version-controlled configuration content. Let's look at the following application.properties file.
