Of course everything as in the previously mentioned cases depends on the general arrangements and design assumptions in the team. Classes from the package Adapter implementation class in this class. In the example implementation of the domain package you can see a large number of classes this is one of the attributes of this pattern. Thanks to this we achieve hermetic implementation of business logic and structures related to it. The access point to domain functions is the facade class. By design domain classes should not use framework classes hence the greater number of POJO plain old Java object classes related to data.
For complex use cases you can create more classes that implement business logic. In the example you can for example separate account activation into a separate class.

By using access modifiers to classes and methods we hide implementation details that is we use the socalled class encapsulation. We thus provide control over access status and behavior of the facility. In our example in the domain package public access is available to the facade class and classes representing input and output data.
All logic implementation is encapsulated at the package level and operations can only be accessed via methods defined in the facade class. What about libraries like Lombok JSR validation or loggers in the domain package? According to the main idea of hexagonal architecture we should not use external libraries. However practice proves otherwise. What libraries we use within the domain depends on the team's decision because each person in the team has different experiences and ideas. However it is worth applying some restrictions to these tools. In the projects in which I participated we were mainly limited to libraries such as java commons mappers and validation libraries.
