I started with an empty project (Quarkus and MicroProfile), gradually adding features and tests and carrying out refactoring using the bce.design approach. I began with Claude Code, then moved on to Kiro.

There was a general agreement that beautiful Java code can be written really quickly. I hope I surprised some of the attendees! 😊

Some attendees handled 'TrainAboutToDepartException' with impressive speed, which is a positive sign.

A new Quarkus template is now available that provides an essential foundation for building MicroProfile applications using the Boundary-Control-Entity (BCE) architecture pattern. Available at github.com/AdamBien/quarkus-microprofile.

Key Features

BCE Architecture: The code is structured into distinct layers - boundaries (REST endpoints), control logic, and entities. This promotes maintainability while keeping the codebase minimalistic.

MicroProfile-Only: The template includes only JAX-RS for REST endpoints and CDI for dependency injection. No external dependencies.

Modular Structure:

• service: Core Quarkus application with BCE structure
• service-st: Separate system tests module

Technical Foundation

Built on Quarkus for fast startup and low memory footprint. The BCE pattern is the simplest way to organise your code, scaling to complex enterprise applications.

Getting Started

Clone the repository (github.com/AdamBien/quarkus-microprofile) and start building immediately. All necessary configuration files and basic project structure are included.

Arguably the oldest architecture pattern, BCE/ECB is described in countless articles and books, and is supported by most (all) design (drawing? 😊) tools.

Boundary Control Entity (BCE/ECB) is built on a simple structure that focuses on the business domain. A component is a (Java) package or module (e.g. ESM in Web Components) that focuses on a real business concept.
