Eureka Server provides a service registry. For details, see the project's GitHub page. By default, the services of this project don't use Eureka to reduce the complexity of the deployment (one less service that needs to be started).
Eureka Server is a Spring Boot application and its dependencies are managed with Apache Maven. To get started, install Java and Maven:
- Make sure you have Java 8 or higher installed.
- Install Maven (see https://maven.apache.org for installation instructions). Note that most IDEs, such as the Spring Tool Suite, already contain a bundled copy of Maven. If this project is only built and launched from within the IDE, this step can be skipped.
In order to launch the Eureka Server application, you can run the command mvn spring-boot:run and open http://localhost:8761.
Alternatively, you can download and install the Spring Tool Suite:
- Install Spring Tool Suite (you can download the IDE from https://spring.io/tools/sts)
- Start Spring Tool Suite and create a new workspace or open an existing one
- Import the project:
- Go to File -> Import -> Maven -> Existing Maven Projects
- Select the
LakesideMutualrepository as the root directory - Enable the check mark for the
customer-coreproject - Click Finish to import the project
- Right-click on the project and select Run As -> Spring Boot App to start the application
By default, the Spring Boot application starts on port 8761. If this port is already used by a different application, you can change it in the
src/main/resources/application.properties file. Please note that all other backend services' application.properties now also need to be adjusted!
By default, the other services don't use Eureka. To enable Eureka discovery, start the other backend services using with the SPRING_PROFILES_ACTIVE=eureka environment variable set. For example
cd customer-management-backend
SPRING_PROFILES_ACTIVE=eureka mvn spring-boot:run
