spring-modulith-sample VS jmolecules

I've created a sample app to play with: it emulates the home page of an online shop. The home page is generated server-side with Thymeleaf and displays catalog items and a newsfeed. The latter is also accessible via an HTTP API for client-side calls (that I was too lazy to code). Items are displayed with a price, thus requiring a pricing service.

Spring Modulith is the successor of Oliver Drotbohm's Moduliths project (with a trailing S). It uses both ArchUnit and jMolecules. At the time of this writing, it's experimental.

You could move towards modeling your code around DDD building blocks (like aggregates etc.) and declare those concepts in code explicitly using jMolecules types. There is a dedicated jMolecules Integrations ByteBuddy Plugin, that would then add the necessary boilerplate code and default mappings required by the expressed concept. This makes the code shown here a fully working JPA model. You can argue that the lack of JPA oddities is odd itself in the first place but I like the idea of expressing the architectural concept explicitly and the technology integration completely flowing from that.
