HabrСоздаем Spring Boot Starter для Kafka с Avro: пошаговое руководствоИнтеграция Apache Kafka в проекты на Spring Boot часто требует много boilerplate-кода. В этой статье я делюсь опытом создания кастомного стартера kafka-spring-boot-starter, который упрощает настройку продюсера и консюмера Kafka с поддержкой Avro-сериализации. Рассказываю, как решал проблемы с тестами (например, auto.offset.reset=latest) и адаптировал стартер для гибкой работы со схемами. Вы найдёте примеры конфигураций для надёжной доставки, потоковой обработки и ретраев, а также лучшие практики разработки стартеров. Бонус в конце — удобный обзор ключевых настроек Kafka для продюсера и консюмера.<a href="https://habr.com/ru/companies/sberbank/articles/894402/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/companies/sberbank/articles/894402/</a><a href="https://zhub.link/tags/kafka" class="mention hashtag" rel="nofollow noopener" target="_blank">#kafka</a> <a href="https://zhub.link/tags/spring_boot" class="mention hashtag" rel="nofollow noopener" target="_blank">#spring_boot</a> <a href="https://zhub.link/tags/%D1%81%D1%82%D0%B0%D1%80%D1%82%D0%B5%D1%80" class="mention hashtag" rel="nofollow noopener" target="_blank">#стартер</a> <a href="https://zhub.link/tags/java" class="mention hashtag" rel="nofollow noopener" target="_blank">#java</a> <a href="https://zhub.link/tags/avro" class="mention hashtag" rel="nofollow noopener" target="_blank">#avro</a> <a href="https://zhub.link/tags/%D0%B0%D0%B2%D1%82%D0%BE%D0%BA%D0%BE%D0%BD%D1%84%D0%B8%D0%B3%D1%83%D1%80%D0%B0%D1%86%D0%B8%D1%8F" class="mention hashtag" rel="nofollow noopener" target="_blank">#автоконфигурация</a> <a href="https://zhub.link/tags/%D0%BF%D0%BE%D1%82%D0%BE%D0%BA%D0%BE%D0%B2%D0%B0%D1%8F_%D0%BE%D0%B1%D1%80%D0%B0%D0%B1%D0%BE%D1%82%D0%BA%D0%B0" class="mention hashtag" rel="nofollow noopener" target="_blank">#потоковая_обработка</a> <a href="https://zhub.link/tags/testcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#testcontainers</a>

Habr[Перевод] Концерт для Java с ИИ — разработка готовых к продакшен LLM приложений (часть 2)Команда Spring АйО перевела и адаптировала доклад Томаса Витале “Concerto for Java and AI — Building Production-Ready LLM Applications”, в котором рассказывается по шагам, как усовершенствовать интерфейс приложения с помощью больших языковых моделей (LLM). В качестве примера автор доклада на глазах слушателей разрабатывает приложение-ассистент для композитора, пишущего музыку для фильмов. В первой части рассказывалось о том, какие подходы автор доклада применил к стоящей перед ним проблеме. Также было показано начало работы над усовершенствованием интерфейса программы-помощника с использованием ИИ. Во второй части будет продолжен рассказ о том, как еще больше улучшить программу. Но сначала поговорим о безопасности.<a href="https://habr.com/ru/companies/spring_aio/articles/893052/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/companies/spring_aio/articles/893052/</a><a href="https://zhub.link/tags/llm" class="mention hashtag" rel="nofollow noopener" target="_blank">#llm</a> <a href="https://zhub.link/tags/spring_ai" class="mention hashtag" rel="nofollow noopener" target="_blank">#spring_ai</a> <a href="https://zhub.link/tags/postgresql" class="mention hashtag" rel="nofollow noopener" target="_blank">#postgresql</a> <a href="https://zhub.link/tags/grafana" class="mention hashtag" rel="nofollow noopener" target="_blank">#grafana</a> <a href="https://zhub.link/tags/testcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#testcontainers</a> <a href="https://zhub.link/tags/embeddings" class="mention hashtag" rel="nofollow noopener" target="_blank">#embeddings</a>

Andre HofmeisterI'm thinking about leveraging Fody in <a href="https://mastodon.social/tags/testcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#testcontainers</a> for <a href="https://mastodon.social/tags/dotnet" class="mention hashtag" rel="nofollow noopener" target="_blank">#dotnet</a> to simplify starting containers and reduce copy-paste code. I'm not sure how it will finally look or work, but early feedback would be greatly appreciated. What do you think? <a href="https://github.com/testcontainers/testcontainers-dotnet/blob/04fb6d051620273fb784a7ee81df449e6ef9d1c7/tests/Testcontainers.Fody.Tests/AutoStartContainerTest.cs" rel="nofollow noopener" translate="no" target="_blank">https://github.com/testcontainers/testcontainers-dotnet/blob/04fb6d051620273fb784a7ee81df449e6ef9d1c7/tests/Testcontainers.Fody.Tests/AutoStartContainerTest.cs</a>

TimHave not used <a href="https://freiburg.social/tags/Testcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Testcontainers</a> Cloud since my trial in the early access phase. Needed to test something with Oracle on my ARM Macbook and remembered that my Docker Pro Account now includes 100 Minutes of Testcontainers Cloud.Nothing short of an amazing product. A little bit too slow for me to use it daily, so I prefer running my containers locally if I have the choice, but just awesome if the Docker Image I'm using is not supported locally.Still, very well done

In the 1st post, I described the app and how to test locally using <a href="https://mastodon.top/tags/Testcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Testcontainers</a> and in a <a href="https://mastodon.top/tags/GitHub" class="mention hashtag" rel="nofollow noopener" target="_blank">#GitHub</a> workflow.
