Getting Started with Spring Boot and OpenFeign


Spring Boot is a popular Java-based framework for building microservices and web applications. OpenFeign is a declarative web service client developed by Netflix for simplifying the process of making HTTP requests. In this tutorial, we’ll explore how to integrate and use OpenFeign in a Spring Boot application.


Before we start, make sure you have the following installed:

  • Java Development Kit (JDK) 8 or later
  • Apache Maven
  • Your favorite integrated development environment (IDE) such as IntelliJ IDEA or Eclipse

Step 1: Create a Spring Boot Project

You can use Spring Initializr ( or your IDE to create a new Spring Boot project. Include the “Spring Web” and “OpenFeign” dependencies.

Step 2: Define a Feign Client Interface

Create an interface that represents the remote service you want to consume. Annotate the interface with @FeignClient and provide the name of the service.

In this example, we’re creating a Feign client for a fictitious “example-service” hosted at

Step 3: Enable Feign Client in the Main Application

In your main application class, use @EnableFeignClients to enable the Feign clients. Specify the base package where your Feign client interfaces are located.

Step 4: Use the Feign Client in Your Service

Now, you can inject the Feign client interface into your service and use it to make HTTP requests.

Step 5: Create a Controller to Expose the Data

Create a controller to expose the data retrieved from the remote service.

Step 6: Run Your Application

Run your Spring Boot application and navigate to http://localhost:8080/fetchData to see the result.

Congratulations! You have successfully integrated and used OpenFeign in a Spring Boot application. This tutorial provides a basic example, but OpenFeign supports more advanced features such as request/response interceptors, error handling, and custom configurations.
