## AI overview

The article explains Spec-Driven Development and the AI Unified Process (AIUP) for a full-stack Java application using Spring Boot, jOOQ, and Vaadin. It presents requirements, an entity model, and system use cases as ordered specification artifacts from which AI can generate code, tests, and documentation.

## Source excerpt

AI is changing how we build software, but many teams still work as if nothing has changed. They treat code as the only reliable artifact. Everything else slowly gets outdated: AI code generation tools can make this even worse if used without structure. They produce code fast, but the process behind the code remains the [...] The post Spec-Driven Development in Practice: How AI Simplify Full-Stack Java appeared first on JVM Advent.
