Getting Started with Spring Boot 3:
This is the code repository backing Baeldung's Java and Spring tutorials — hundreds of small, self-contained Maven modules, each demonstrating one specific technique (Akka actors, Dijkstra's algorithm, Spring Boot features, etc.). It's aimed at Java/Spring developers who want a working code example to copy from rather than prose explanation.
Genuinely broad coverage of the Java ecosystem — Spring, Spring Boot, Spring Security, algorithms, and dozens of third-party library integrations, each isolated in its own module so you can clone/build/run just the piece you need. Actively maintained: the JDK profile list goes up through jdk25/jdk26, and modules get bumped as new JDKs ship. Every module is a real, runnable Maven project with its own pom.xml and tests, not a gist-style fragment.
The repo is enormous (37k+ modules-worth of content), and the README openly warns you'll need to bump git's postBuffer just to clone it — that's a sign of how unwieldy this has gotten as a single monorepo. There's no index or search inside the repo itself; you're expected to already know which module you want from a Baeldung article, so browsing GitHub directly is a poor experience. Quality is inconsistent module-to-module since this is essentially the source for a content-marketing operation (the README leads with paid course upsells before anything else) — some examples are excellent, others are thin and clearly written to hit a publishing quota.
