cwa-server VS IDDD_Samples

Schaut euch das zeug auf github an: https://github.com/corona-warn-app/cwa-server

Which means that the Java philosophy is too "fat" for you if I understood you. Real world Java controller.

I found this pattern in: corona-warn-app

Go there and get your test for free. You have to register and will get your result by email, download or in best cases within germany's https://www.coronawarn.app/

This is the backend of germanies contact tracing App. It's beeing developed by SAP https://github.com/corona-warn-app/cwa-server

Here is the direct link:https://github.com/VaughnVernon/IDDD_Samples/blob/master/iddd_collaboration/src/main/java/com/saasovation/collaboration/domain/model/forum/Discussion.java

"domain" is real domain that contains business logic, "ddd" should be extracted to a common library (according to this example https://github.com/VaughnVernon/IDDD_Samples/tree/master/idd... and this one https://github.com/dddshelf/ddd)

Regarding to other issues, could you add little bit more concrete details just to check and consider possible solutions.

I try to apply DDD in my microservices, and will use a UUID generated by code as the primary key (based on how Vaughn Vernon defines a nextIdentity method in his repositories). That way, an entity always has an ID as soon as it is created. I don't need to persist it first in order for it to have an ID, and you can already identify the entity and use it in maps (since it has a hashcode generated solely by the ID), or you can publish domain events. Some nice benefits...

I would say this: link
