Now it's time to consume our registered service. We'll discover it and then consume it with Spring's RestTemplate by providing the host and port values of the service:

@EnableEurekaClient
@SpringBootApplication
public class EurekaWeatherServiceClient {
    public static void main(String... args) {
        SpringApplication.run(EurekaWeatherServiceClient.class);
    }
   
    @Autowired
    private EurekaClient eurekaClient;
    
    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        return builder.build();
    }

    @Bean
    public CommandLineRunner run(RestTemplate restTemplate)
            throws Exception {
        Application application = eurekaClient
                .getApplication("spring-cloud-eureka-client");
        InstanceInfo instanceInfo = application.getInstances().get(0);
        String hostname = instanceInfo.getHostName();
        int port = instanceInfo.getPort();

        return args -> {
            String result = restTemplate.getForObject(
              "http://" + hostname + 
              ":" + port + "/temperature", String.class);
            
            System.out.println(result);
        };
    }
}
