But for the 90% of software that is business applications, Spring Boot’s developer experience is dramatically superior – and AI-assisted development has eliminated the last argument against Java’s annotation-driven model.https://blogs.joshuaantony.com/posts/overengineering-microservices/Thu, 02 Apr 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/overengineering-microservices/HAProxy sidecars for mTLS. Hystrix for circuit breaking. Apache Camel between layers within the same service. Six API versions. A mandated common framework. A squash merge ban. Each decision was defensible. Combined, they created a system that took three months to onboard into.https://blogs.joshuaantony.com/posts/hybris-occ-rest-facade-over-stateful-monolith/Mon, 30 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/hybris-occ-rest-facade-over-stateful-monolith/SAP Commerce OCC promises a stateless REST API for headless commerce.

Deep chaining, invisible runtime graphs, and JVM heap exhaustion are the consequences.https://blogs.joshuaantony.com/posts/hybris-persistence-layer-fear-of-orms/Sun, 22 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/hybris-persistence-layer-fear-of-orms/Hybris gave engineers a beautifully simple API – modelService.create(), modelService.save(), modelService.remove(). Underneath, it fired hundreds of invisible queries, consumed unbounded memory, made bulk operations impossibly slow, and refused to let you delete data. This is why people are scared of ORMs.https://blogs.joshuaantony.com/posts/playwright-is-not-a-backend-api-testing-tool/Sun, 15 Mar 2026 00:00:00 +0000https://blogs.joshuaantony.com/posts/playwright-is-not-a-backend-api-testing-tool/Using Playwright for backend API testing in a Spring Boot repo is not reuse – it’s dual-stack maintenance. The right tool depends on what you’re verifying, not what you already have installed.
