Назад в 2005-й. API-first как третья пилюля от деградации проекта под LLM

Агент отчитался: экран настроек готов. Поля редактируются, после сохранения выскакивает тост «Сохранено». Я нажал F5 — все настройки вернулись к дефолтным. Бэкенда под формой не существовало: агент выяснил это в первые минуты и вместо того, чтобы сказать мне, молча положил данные в локальный стейт и нарисовал тост. Ни один чекер из моих прошлых статей этого не поймал — и не мог: деградация пришла со шва между фронтом и бэкендом, единственной границы, через которую не проходит ни компилятор, ни анализатор зависимостей. Под катом — как этот шов гниёт под LLM и как его чинит contract-first: генерация серверных интерфейсов и клиента из одного OpenAPI-файла, политика ломающих изменений, правило «не симулируй — расширяй контракт». Попутно — зачем возвращаться к идее, которую мы выбросили вместе с WSDL, и какая из моих проверок после всего этого молча перестала работать. Третья часть цикла, читается самостоятельно.

🏗️ Workshop at Workshop-Tage 2026: Architecture: Creating Architectural Fitness Functions using ArchUnit

How can you make sure that your software architecture is not only planned, but also followed over time? This is exactly what this hands-on workshop by Venkat Subramaniam on Architectural Fitness Functions with ArchUnit is all about. 🔍 In this workshop, you will learn about different fitness functions that help architects and teams assess the architectural soundness of their systems. You will then implement these rules as practical guardrails using ArchUnit and receive continuous feedback on whether your architectural expectations are being met.

📅 Tuesday, September 8,
from 🕘 9:00 AM

Шёл за утечкой памяти, нашёл утечку диска: SXSSFWorkbook без dispose() в Apache POI

Меня зовут Игорь Симаков, работаю engineering manager’ом и руковожу командами разработки На одном из наших сервисов, который работает с XLSX-файлами, прилетел production-алерт на высокое потребление памяти. Стандартный P3, обычно решается рестартом. Пошёл смотреть поды и нашёл проблему, к памяти отношения не имеющую, но представляющую больший риск, чем сам алерт. Об этом и расскажу ниже: чем «утечка диска» отличается от «утечки памяти», как мы наткнулись на грабли в Apache POI и как закрыли их на уровне архитектуры

[Перевод] Руководство по ArchUnit — как модульно тестировать архитектуру

Соблюдение определённой структуры пакетов или архитектуры крайне важно. Особенно в Java, где для корректной работы некоторые элементы должны быть public или действительно доступны за пределами своего пакета. В новом переводе от команды Spring АйО рассмотрим библиотеку с открытым исходным кодом ArchUnit, которая помогает в тех случаях, когда одного компилятора недостаточно.

Architecture boundaries aren’t optional—they’re guardrails.
With Quarkus + ArchUnit, you can turn BCE/ECB principles into executable tests that fail the build when boundaries erode.

ArchUnit против хаоса

Привет! Я Масгутов Руслан, архитектор в Т-Банке. Одна из моих задач — вести архитектурный надзор по техническим решениям. Проверка структуры проектов при ревью довольно быстро становится скучной рутиной, и появляется желание автоматизировать эту деятельность, чтобы освободить время для более интересных задач. Расскажу, как мы используем ArchUnit для автоматизации архитектурного контроля. Покажу, как мы обернули правила в Gradle-плагин, встроили их в CI/CD, боремся с архитектурными отклонениями до того, как они попадают в pull request, и расскажу о возможности сбора архитектурных метрик.

It was a successful weekend for #Komunumo, the new federated meetup alternative: Now there is a header on every page, and on the homepage the communities are displayed with their picture in a responsive grid. Architecture tests with #ArchUnit were introduced and thanks to #TDD we have a test coverage of 100%. This gives us a good feeling for refactorings and also when testing PRs. I'm already looking forward to spending a few evenings working on it next week! Screenshots will follow soon! 🤓

TIL: #ArchUnit 1.4.0 was released almost three weeks ago 🎉

The new version supports the upcoming #Java 24, enables the use of @AnalyzeClasses as a meta-annotation, improves the performance of transitive dependency checks – and includes several other useful improvements.

Unit test your architecture with @archunit! ❤️

2/ Potential improvements:

* The docs could have an even simpler "Getting started" example or feature overview. Some colleagues had a hard time to quickly grasp what Spring Modulith actually does
* I wish it could also verify basic inner module structure like no cycles between module layers or only top-down access allowed within module layers. Maybe this is not within the intended scope of Spring Modulith. Will keep using #archunit for this aspect.

@javahippie Das Aufwand-Argument ist einer der Treiber hinter #jMolecules: Annotationen und Interfaces für etablierte Mustersprachen. Darauf aufbauend dann Zweizeiler für die Verifikation per #ArchUnit (https://github.com/xmolecules/jmolecules-integrations/tree/main/jmolecules-archunit) / #jQAssistant. Teilweise sogar schon per Compiler / APT (https://github.com/xmolecules/jmolecules-integrations/tree/main/jmolecules-apt). Niemand will solche Regeln ständig neu schreiben.

Today (on my live coding stream) I found that the best way to get ChatGPT 4 to give you a good answer is to give it an already working answer, ask it to simplify it, and then correct its wrong answer with information provided by a viewer.

Otherwise it was over an hour of trying (and failing) to get it to create a working ArchUnit test that would compile, let alone test the right thing.
