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

3. Configure application.yml:

yamlCopy
server:
  port: 8888
spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/your-repo/config-repo
