Today, we'd like to continue the topic about building microservices and move from Fat (Uber) JAR to Thin JAR for Spring Boot projects. Thin JAR represents compiled and packaged application code (business logic) of the project together with the third-party libraries it depends on. Compared to Fat, it does not contain application server runtime by default, so the size of a Thin archive is much smaller. The runtime and dependencies are automatically downloaded during the first launch and stored locally in the ~/.m2/repository. To showcase the process of building a framework inside the Java Engine with Thin JAR for running microservice architecture, we'll use a pre-configured package of Maven and the popular Spring Boot.
