Tactical Domain-Driven Design with Java and Spring This workshop explores tools and approaches for implementing tactical Domain-Driven Design (DDD) in Java, focusing on the jMolecules library for expressing DDD concepts and the Spring Modulith project for modular Spring Boot applications, including support for integration, events, testing, and documentation of rich domain models.

📢 Another update for the Logical Structure view in #VSCode's Spring Boot Tools. The application node now reveals a customization icon to select the stereotype groups that should be considered. Switch to the pre-release version to play with it. ☕️⚗️ #jMolecules
The Logical Structure view in VSCode's Spring Boot Tooling showing the Spring Modulith application modules of the RESTBucks application. The application node reveals an icon to open up a dialogue to select the stereotype groups that are supposed to be included in the project tree. A screenshot of the stereotype group selection view.

Lovely how @dirkmahler.bsky.social showcases rule validation of architecture that is against an intended architecture using #jMolecules for the former and #ContextMapper for the latter. #jsd2025 ☕️⚗️
A presentation slide titled "APPLICATION STRUCTURE" discusses jQAssistant rules that validate against abstract concepts, such as Bounded Context and Technical Aspects. It illustrates relationships between concepts like "Implemented Bounded Context," "Documented Bounded Context," the former bound to jMolecules annotations and the latter described by Context Mapper.

KISS. If you use Spring, consider using Spring Modulith. If not, I'd advise to use jMolecules/ArchUnit.

Update on the logical project view coming in #STS (flip your #SpringBoot tools to pre-release versions in #VSCode):

- Alphabetic sorting of the stereotypes per level
- Icons! (at least for some of them) 🔥

Up next: #SpringModulith groupings by application module.

⚗️🍃📦 #jMolecules #DDD #Spring
A refined variant of the logical structure view in VSCode displaying application structure based on architectural, design and technology stereotypes in a tree-like structure.

@odrotbohm i did find examples for modulith with cqrs and hexagonal, but they don't use jmolecules, and I found no examples for usage of modulith with jmolecules-onion-architecture.

@odrotbohm I am looking for an example that demonstrates a sliced onion application with jmolecules ddd *and onion* support. Modulith is quite opinionated about the package structure of the domain ring, but what about the application and infrastructure/rest/db rings? Where should I put my […]

To play with that in #VSCode, flip your Spring Boot tools to pre-release and use jMolecules annotations or interfaces in your projects. Be reminded that this is just a start. We're going to add #SpringModulith support soon and allow selecting which stereotype groups you want to see. Give it a try!

Double sneak preview! #jMolecules 2.0 is going to introduce a declarative stereotype concept for predefined ones (DDD, Spring) and custom ones declared in your projects. The #STS team has a prototype to turn that information into a project tree for higher-level project navigation. ☕️⚗️
