Next, we are going to reuse the Spring Boot-based temperature service that we created in Chapter 1, From Monoliths to Microservices.

First, we'll define the Maven dependencies for Eureka as shown here: 

<dependency>
    <groupId>org.springframework.cloud</groupId> 
    <artifactId>spring-cloud-starter-eureka</artifactId> 
    <version>1.4.0.RELEASE</version>
</dependency>
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-databind</artifactId> 
    <version>2.9.0</version>
</dependency>
<dependency> 
    <groupId>org.springframework.cloud</groupId> 
    <artifactId>spring-cloud-netflix-eureka-client</artifactId> 
    <version>1.4.0.RELEASE</version>
</dependency>

Then, we'll add the @EnableEurekaClient annotation to our application configuration:

@EnableEurekaClient
@SpringBootApplication
public class EurekaWeatherService {
    public static void main(String... args) {
        SpringApplication.run(EurekaWeatherService.class);
    }
}

To make our temperature service aware of the Eureka Server, we are going to add some configurations, defined in a .YML file, as follows:

spring:
   application:
      name: spring-cloud-eureka-client
server:
   port: 0
eureka:
   client:
      serviceUrl:
         defaultZone: ${EUREKA_URI:http://localhost:8761/eureka}
    instance:
         preferIpAddress: true

After invoking the main method on the EurekaWeatherService class and then requesting http://localhost:8761, you should see that our application is registered with the server:
