Java is supposed to be object-oriented, but too many codebases look like procedural spaghetti. Many enterprise Java microservices devolve into procedural scripts with global state, long functions, and poor encapsulation.

In this live coding session, we’ll take a messy procedural Spring Boot application and refactor it step by step into a modular, testable, and maintainable object-oriented microservice.

If you’ve ever been frustrated by rigid, procedural Java that resists change, this session will give you practical techniques to fix it.
