Introduction to Spring Modulith - Modular Monoliths in Spring Boot

Подписывайся на наши соц сети: Stuck choosing between a messy monolith and the complexity of microservices? There's a sweet spot in between which is a modular monolith and Spring Modulith makes it incredibly easy to build one in Spring Boot. In this hands-on tutorial, we walk through the Spring Modulith project step by step. Starting with a standard Spring Boot monolith, we identify architectural problems like hidden coupling and dependency cycles, then progressively refactor the app into a well-structured modular monolith with enforced boundaries, domain events, and durable event publication. You'll see real code, real tests, and real architecture verification in action. • Understand what a modular monolith is and why it's the right choice for most applications • Learn how Spring Modulith turns packages into enforced application modules with public APIs and hidden internals • Detect dependency cycles and boundary violations automatically with verification tests • Decouple modules using Spring application events and the @ApplicationModuleListener annotation • Make events durable with the Event Publication Registry so no notification is lost on crash or restart If you found this helpful, smash that thumbs up button, subscribe for more Spring Boot content, and let me know in the comments — are you building modular monoliths with Spring Modulith?
