Master Microservices with Spring Boot and Spring Cloud - Step 17 – Invoking Currency Exchange from Currency Conversion M

The video tutorial explains how to call a currency exchange microservice from a currency conversion microservice using RestTemplate in Spring Framework. It covers creating dynamic URLs with URI variables, mapping responses to a currency conversion structure, and calculating the total amount based on conversion rates. The tutorial concludes with testing the service and preparing for further exploration of Spring Cloud features.
