Design / pattern question regarding the use case

[sebastienblanc]

I have the following architecture :

• A bookstore service where you create books and authors.
• A SellingPoint service that has the current model :
  • A SellingPoint entity with name, longitude , latitude , and a Set<Book>
  • Book is an entity duplicated from the bookstore service and simplified , it contains just one attribute isbn

Now when a the bookstore service creates a book, I would like to send a message/call an endpoint to the SellingPoint service to add the book entry there as well (and automatically , see it as a sort of sync) .

What is the best way to do it ?

1. Call an endpoint on the SellingPoint service on JPA creation in the bookstore service : this one is easy to implement
2. But maybe using Camel/activemq would be a nice thing to show , @cmoulliard wdyt ?

We could use Camel to expose the Selling endpoint as Rest Service but ... remember what we discussed this Monday. Due to the time constraint for the delivery - 19/09, we have decided to postpone the inclusion of integration stuff !

To answer to your question, we could also easily implement that using camel ate the condition that the camel-jpa fraction works well. I haven't yet tested it.
