Hi Adam!

Regarding the BCE Pattern,

• If I wanted to use repository pattern where should I setup the repository class? In the control or entity?
• And what about the RestClients? The RestClient should be on the control and the requests and responses class on the entity or everything on the entity? e.g. For a Shopping Cart Rest API, with external products, should I have a package "cart" with everything regarding it, and another one called "product", the control would have the service with all the logic regarding biz, and that service would communicate with the RestClient on the entity. Because that restclient is considered data and domain logic?

Thanks in advance and keep up the amazing work!

Before i saw someone using secureRandom class or something like that for generating random numbers(to generate a verification code for email verification ) is it different from using Random class...i know that they use different algorithms but what do they mean by more secure ?😅

Hi Adam, long time no writing but watching every session as always.
I am working on a government project, using Quarkus as always and I would like to integrate log collection, metrics and telemetry by using the least configuration possible. What would be your choice of tools to use? Graylog? ELK? LGTM?

Regards,
D.

Hi again Adam!

One more question, I see that you expose the JPA entity on the boundary layer, sometimes as a response and others as a request. What is the best approach if you need to do some bean validation on those objects to return 400? Is to create a specific class for the request? Or you add the bean validations annotations to the jpa entity class? Or create a method to validate and if there is a problem it returns 400?

e.g. the ebank repository that you have, imagine that you wanted to return 400 if you try to create an account without the name of the person (new field) you would add that validation to the method “isValidForCreation”?

Thanks!

Hi Adam,

This is not a question but a suggestion. It would be cool if you brought on the LangGraph4J (a sister project to LangChain4J) developer on your podcast. From the project page: LangGraph for Java. A library for building stateful, multi-agents applications with LLMs, built for work with langchain4j
