Spring Boot
Spring Boot helps you to create Spring-powered, production-grade applications and services with absolute minimum fuss.
In this tutorial, I'll walk you through how I moved beyond basic logging by instrumenting a Kotlin and Spring Boot backend service with OpenTelemetry. You'll learn how OpenTelemetry's tracing model gives you the execution context that logs alone can't provide. By the end of this guide, you'll have a working instrumented service and a clear mental model for building more observable backend systems.

JHipster
JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."
Even worse, 95 (60%) of those pull requests were merged into the main branch, 50 of them by a bot user, without any user interaction. This led to the malicious package being pushed to production code in less than an hour, as showcased by the jhipster/generator-jhipster repository.

Project mention: CAS Internals – 825 pages on how a 400-module Spring Boot app works | news.ycombinator.com | 2026-03-27
I've been a committer on Apereo CAS (https://github.com/apereo/cas) since the 3.0 days. It's an open-source SSO/identity platform - 400+ modules, Spring Boot 3.x, Java 21+. Deployed at thousands of universities, government agencies, and enterprises.
I wrote a book that walks through how the whole thing works internally - not configuration, but actual code paths. 30 chapters, 825 pages. The Spring Boot bootstrap sequence, the authentication pipeline, Webflow state machines, ticket registry internals, SAML2/OAuth2/OIDC protocol engines.
