As a mentor I want to:

1. SpringJDBC present in our app
2. UserRepositoryImpl should contain implementation of methods from UserRepository

As a mentor a want to have Swagger2 configuration in the app/../configuration package

As a mentor, i want to have a User domain object:

1. should have next fields:

• String firstName
• String lastName
• String password
• String email
• Long id (for this would be better to create new common domain BaseEntity, but do not specify the type of field - use generic)
• LocalDate createdDate (create separate domain for this 5 fields - StoredEntity)
• LocalDate updatedDate
• String createdByUser
• String updatedByUser
• int version

2. Implement Builder for this class

1. Create separate module util
2. Create AlexIterator interface with the following methods next(), hasNext()
3. Create AlexCollection interface with the next methods: add, remove, size, iterator
4. Create AlexCatCollection class and implement all methods. This collection should work only with Cat objects and all their implementations (PersianCat, SiameseCat, SphynxCat etc.)

As the result I want to have a manually created collection (without using Java Collection API) so that I could store all my cats in one place. And in case if I need to feed them I should have ability to iterate by this collection.

As a mentor I want to have:

1. UserServiceImpl class in the service/../impl package with the implementation of methods from UserService interface
2. Also add UserRepository interface into repository/../api package with appropriate methods for CRUD operations.

As a mentor I want to have a UserController class in the app/.../controller package with the following REST APIs:

1. GET user/{id} - for finding user by identifier
2. POST user/add - for adding new user
3. DELETE user/{id} - for removing user by identifier
4. PUT user/update
5. Add UserService interface into service/../api package with appropriate abstract methods for controller (All CRUD operations)

As a mentor I want to have JaCoCo plugged to the project to have ability generate coverage report with helpful of site/install maven commands

As a mentor I want to have:

1. UserService should be covered by Unit tests
2. UserRepository should be covered by Unit tests
3. UserController should be covered by Unit tests
