* https://www.baeldung.com/hibernate-5-spring went to spring-jpa-2

* https://www.baeldung.com/transaction-configuration-with-jpa-and-spring went to spring-jpa-2

* https://www.baeldung.com/persistence-layer-with-spring-and-hibernate went to spring-jpa-2

* https://www.baeldung.com/simplifying-the-data-access-layer-with-spring-and-java-generics went to spring-jpa-2

* https://www.baeldung.com/the-persistence-layer-with-spring-data-jpa went to spring-data-jpa-repo-2

* https://www.baeldung.com/spring-data-jpa-query went to spring-data-jpa-query-2

* https://www.baeldung.com/spring-jdbc-jdbctemplate moved to spring-jdbc

* Removed spring-persistence-simple module as all articles have been moved
