Our Questions Management application currently has 8 services including 3 Core Service, 2 Composite Service, and 3 API Service. To register them with Eureka Server, as I mentioned in the tutorial Register services with Eureka Server using Eureka Client, with Spring Cloud Netflix, the first thing we need to do is to add the Eureka Discovery dependency into all service projects. You open the pom.xml file for each service project and add the new Eureka Discovery dependency as follows:
Here, I also added the Spring Boot Actuator dependency to enable the service information in the Questions Management application. You can find out more about the Spring Boot Actuator here.
Next, we will declare the @EnableEurekaClient annotation to each main class of each service project:
- ApiCategoryServiceApplication of the api-category-service project
- ApiOptionServiceApplication of the api-option-service project
- ApiQuestionServiceApplication of the api-question-service project
- CompositeOptionServiceApplication of composite-option-service project
- CompositeQuestionServiceApplication of the composite-question-service project
- CoreCategoryServiceApplication of the core-category-service project
- CoreOptionServiceApplication of core-option-service project
- CoreQuestionServiceApplication of the core-question-service project
Next, in the application.properties file of each service project, you add the information of the Eureka Server that we will register for each service.
The last step is to name each service to distinguish them from the Eureka Server.
I’ll take the name of each service and add a new spring.application.name=<service_name> property in the application.properties file.
For example, for the API Category Service, the value of the spring.application.name project is as follows:
spring.application.name=API Category Service
OK, that’s it. Please try to start all project services, server and then visit http://localhost:8761/ to see the results!
