Eureka and Spring Cloud Gateway Integration in Java Spring Boot Microservices: Linking Services for Streamlined Navigation
In this tutorial, we will guide you through the process of integrating a Eureka Service Discovery Server, an API Gateway using Spring Cloud Gateway, and a Demo Microservice registered with Eureka. The creator of this tutorial is AmiyaRanjanRout.
To begin, let's create a new Spring Boot Project with specific dependencies. The project requirements include Spring Web and Eureka Discovery Client. Once the project is set up, we will proceed to develop a Java Spring Boot Microservice for Service Discovery using Eureka.
The API Gateway, built on Spring Cloud Gateway, offers several key features such as integration with Circuit Breaker, Spring Cloud DiscoveryClient, predicates and filters, path rewriting, and more. Developing an API Gateway requires creating a new Spring Boot Project with specific dependencies.
For the API Gateway, we will configure it to forward requests to the DEMO-SERVICE based on the predicate . The DemoController class has been created in the directory.
The application.yaml file needs changes for the id, uri, and predicates. Similarly, changes have been made to the application.properties file to accommodate the new setup.
Once the API Gateway is in place, accessing all microservices can be done using only one port, as they can be configured in the API Gateway.
To test the API, run all three applications and make requests to the following URLs using Postman:
- API Gateway: [API Gateway URL]
- Eureka Dashboard: [Eureka Dashboard URL]
- Demo Microservice: [Demo Microservice URL]
It's important to note that this tutorial demonstrates the use of Eureka Dashboard. However, the search results do not provide the name of the author of the Java-Spring-Cloud tutorial describing the implementation of Eureka Service Discovery and an API Gateway using Spring Cloud Gateway.
Spring Cloud Gateway is an API Gateway built on Spring Framework 5, Project Reactor, and Spring Boot. It serves as a versatile tool for managing and routing requests in microservice-based architectures.
While this tutorial focuses on integrating the Eureka Service Discovery Server, API Gateway, and Demo Microservice, it's worth mentioning that the creation of the Demo-Service is not detailed in the provided paragraph. For a more comprehensive understanding, you may refer to additional resources or tutorials on creating Java Spring Boot Microservices.
