The main specifications of the application are:
• Create a Spring Boot project containing the REST services for comunicating with the database.

o obtaining the list of the persons, via a HTTP GET request.
o adding a new person in the database, via a HTTP POST request. o modifying the name of a person, via a HTTP PUT request.
o deleting a person, via a HTTP DELETE request.
• Test your services using the browser and/or Postman.
• Create REST services for inserting and reading relationships.
• Create services for determining the first k most/least connected (popular) persons in the network.
• Integrate the services into your previous project, invoking them using the support offered by Spring Boot.
• Handle the exceptions using a RestControllerAdvice.
• Write a service that determines in linear time all persons who are so important to the social network such that, if one of them were eliminated, the network would become disconnected.
• Document your services using Swagger or a similar tool.
• Secure your services using the HTTPS protocol and JSON Web Tokens
