This repository presents a basic example of Spring Data JPA in comparison with JPA and JDBC.
  It is based on Spring and Maven.
  
  In order to run the code you need to have a MySQL server running and have a schema named `mydb`;
  or you can change the URL in `application.properties`. At the first run you need to change 
  `hibernate.hbm2ddl.auto=create` in the same file, in order to let Hibernate to create the schema.
  After this, change it back to auto.
  
  There might be problems with running the jdbc tests because the id generation is trivial (and probably 
  wrong in some cases). If problems occur delete everything in the database (or run the tests for jpa).
