🚀 Feign Client In Spring Boot | MicroServices Communication Made Easy ✅

In this video, we learn how to use Feign Client in Spring Boot to simplify communication between microservices 🚀 Instead of writing manual HTTP calls using RestClient or RestTemplate, Feign allows us to call other services just like a normal Java method. We will build a real example where an Order Service communicates with an Inventory Service using Feign Client and understand how it works internally at a high level. 📚 What You’ll Learn • What is Feign Client • Why Feign is needed in microservices • How to enable Feign in Spring Boot • Creating Feign Client interface • Calling another microservice using Feign • High-level internal working of Feign • Feign vs RestClient 🧩 Project Overview We use: Order Service Inventory Service LINKS: Git Repos - https://github.com/codesnippetjava/ec... https://github.com/codesnippetjava/ec...
