– pom.xml contains dependencies for Spring Boot Web, JDBC and MySQL Connector. – Configuration for Spring Datasource, MySQL database in application.properties. – TutorialController is a RestController which has request mapping methods for RESTful requests such as: getAllTutorials, createTutorial, updateTutorial, deleteTutorial, findByPublished…

It uses JdbcTemplate for executing SQL queries or updates to interact with Database. – JdbcTutorialRepository implements TutorialRepository. It will be autowired in TutorialController. – TutorialRepository is an interface that provides abstract methods for CRUD Operations and custom finder methods. – Tutorial data model class corresponds to entity and table tutorials.

Spring Boot 2.5.5 (with Spring Web MVC, Spring Data JDBC).

– The database will be MySQL by configuring project dependency & datasource. – We make CRUD operations & finder methods with Spring Data Jdbc. Log =Logger.getLogger( all Tutorials which title contains keyword Import .jdbc.AbandonedConnectionCleanupThread
