🥁📢 #jMolecules 2025.0.2 is out (2.0.1 spec, integration 0.33)! New features in the integrations: annotation generation for reflective metadata generation for domain types on #GraalVM. Avoid custom integration for embeddable records on Hibernate 7+. ☕️⚗️ github.com/xmolecules/j...

Oliver Drotbohm - jMolecules 2.0 – Stereotypical

🥁📢 #jMolecules 2.0 is here! I took the chance to summarize the new stereotypes feature that enabled the #Spring Tools team around @martinlippert.bsky.social to bring logical browsing of your projects to your IDE. ☕️⚗️🍃

The recording of my yesterday‘s “Tactical Domain-Driven Design with #Java and #Spring” at #Devoxx is already up on YouTube… youtu.be/k3o1nSh3g2Q?... ☕️🍃⚗️ #DDD #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.

📢 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

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.

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 ☕️⚗️

Spring Modulith 2.0 M3 released Level up your Java code and explore what Spring can do for you.

🥁📢 #SpringModulith 2.0 M3 is out! Revamped #JPA event publication registry, #Jackson 3 support, option to serialize event publication externalization, #jMolecules 2025 upgrade. 🍃📦☕️⚗️ spring.io/blog/2025/09...

Release 2.0 RC2 · xmolecules/jmolecules ⭐ New Features Introduce @Stereotype meta-annotation #152 Move module-info.java to root of the JAR #151 🔨 Dependency Upgrades Upgrade to JUnit 6.0 RC3 #168 Upgrade to Kotlin 2.2.10 #167 Upgrade ...

🥁📢 #jMolecules 2025 RC5 and 2023.3.4 are out! The former ships the new stereotype API and metadata.

☕️⚗️

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.

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

An image displaying a tree structure of a software application, grouping various components by their architectural stereotype, such as Domain Event Handlers, Aggregate Roots, Services, Entities.

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. ☕️⚗️

To all #jMolecules users out there: what's the persistence mechanism you're using in your application? ☕️⚗️

A) Separate persistence model
B) Persistent model (database-generated IDs)
C) Persistent model (application-generated IDs)

We're planning to provide a #jMolecules CLI to generate source code for #DDD artifacts. Any #GitHub Actions / #GraalVM / #jReleaser experts out there who'd be willing to help / contribute the binary distribution setup necessary? Please chime in below… ☕️⚗️🍃📦

Release 0.28 · xmolecules/jmolecules-integrations ⭐ New Features Add configuration options for ByteBuddy code generation #323 🐞 Bug Fixes Allow Association to be used from within a value object #322 🔨 Dependency Upgrades Upgrade to Axon 4.11....

The #SpringModulith / #jMolecules stereotyping prototype is coming together nicely. A customizable stereotype configuration system will support prepared and user-defined stereotypes expressed in codebase elements.

🥁📢 #jMolecules 2023.3.0 (API 1.10, Integrations 0.25) is out! Improved #HexagonalArchitecture verification and persistence code generation. See the release announcement for details. github.com/xmolecules/j... ☕️⚗️

I've summarized the feedback I got in this #jMolecules Integrations ticket. I'd appreciate further input and votes on the proposed solution over there. github.com/xmolecules/j... ☕️⚗️

Enhancing Software Governance and Quality With jMolecules jMolecules uses annotations to enforce architectural rules, prevent software erosion, simplify validation with tools like ArchUnit. It supports DDD, CQRS, etc.
