Spring Boot. How to use Hibernate or Spring Data JPA + Oracle + HikariCP

Most Spring Boot applications need minimal Spring configuration. Spring Boot is an open-source Java-based framework used to create a micro Service. It is developed by the Pivotal Team and is used to build stand-alone and production-ready spring applications.
Hibernate ORM enables developers to more easily writing applications whose data outlives the application process. As an Object/Relational Mapping (ORM) framework, Hibernate is concerned with data persistence as it applies to relational databases (via JDBC).
HikariCP is a fast, simple, reliable, "zero-overhead" and production-ready JDBC connection pool. At roughly 130Kb, the library is very light.
WildFly, formerly known as JBoss AS, or simply JBoss, is an application server authored by JBoss, now developed by Red Hat.
