Скачать или смотреть #75 Spring Framework Day 42 | Service-to-Service Communication with RestTemplate 🚀☕ | Microservices

📌 Welcome to Day 42 of our Spring Framework Series!
In the last session, we built our third microservice – the Plot Service – with its own database and CRUD APIs.

In this session, we’ll take a big step forward and implement Service-to-Service Communication. We’ll use RestTemplate to allow one microservice to call another — enabling data exchange between Employee, Account, and Plot Services.

✅ What You’ll Learn in this Session:
• Introduction to RestTemplate in Spring Boot.
• Configure RestTemplate Bean in Microservice.
• Call Employee Service from Account Service using RestTemplate.
• Fetch Plots for an Employee via RestTemplate call to Plot Service.
• Understand synchronous communication between microservices.
• Test inter-service communication in Postman.

Key Concepts You’ll Understand
• How microservices communicate with each other.
• Difference between calling internal modules in monolithic vs external services in microservices.
• Pros and cons of using RestTemplate for synchronous calls.
• Foundation for moving toward FeignClient and Service Registry (Eureka) in upcoming sessions.

✅ Why This is Important:
• You’ll learn how to connect independent services and share data.
• Build real-world microservices that don’t live in isolation.
• Prepare for advanced concepts like FeignClient, Eureka Discovery, and API Gateway.

🎯 Perfect For:
👨‍🎓 Students learning practical microservices integration.
🧑‍💻 Developers building real-world projects with Spring Boot.
💼 Professionals preparing for enterprise microservice communication patterns.
