title: Multiple stored procedures on two or more (Oracle) databases with Spring Boot?
body: <p>I am setting up a Java Spring project with multiple StoredProcedures to two completely different Oracle databases.
  It is not allowed to use any auto-generated SQL.
  I didn't find anywhere a complete solution or implementation example so I will try to sum up the question and clean solution here.
  I sincerely hope this will help someone someday.</p>
  
  <p>You will need a working Spring Boot project.</p>
  
  <p>Please let me know if there is anything confusing and I should explain it better.</p>
