Java – how do I name repositories and service interfaces?

How do I name the repository and service interfaces and their implementation classes?

For example, I have a model called question You will name the repository (interface and Implementation) and the service (interface / implementation)

After reading these posts: Java interfaces / implementation naming convention and interface naming in Java, I reconsidered what I had done:)

Solution

I think there are roughly two methods of naming in DDD:

1) Based on stereotypes This is where you include the class stereotype in its name For example:

QuestionsRepository,TaxCalculatingService etc

2) Domain based In this approach, you only use the domain language and omit any stereotypes in the class name For example:

Questions (or AllQuestions),TaxCalculator etc.

The implementation class will be named sqlquestions or inmemoryquestions

I've tried two, but now I prefer the second option because it seems to be more in line with the DDD thinking mode It seems more readable and has better signal - to - noise ratio The following is philcal ç ADO's quotation for the inventory of great article:

class OrderRepository {
   List<Order> getOrdersFor(Account a){...}
}

class AllOrders {
   List<Order> belongingTo(Account a){...}
}

The whole article is well worth reading and bookmarking
