Explore how to use spring rest template to perform get, post, put, and delete requests, handle responses, and submit form data with url-encoded payloads.

Add a rest endpoint in the controller that returns a car by index via a path variable, using the index in the business logic to return the car if found.

Programmatically test rest api endpoints by configuring a rest template, performing getForObject and getForEntity calls to controller methods that return cars, and verify response status.

Discover how spring boot auto-configures data sources for jdbc or jpa and connects to H2 embedded databases for development. It automatically creates the database schema on startup and initializes data.

Explore how Spring Boot uses connection pooling to maintain a pool of ready-to-use connections, boosting performance by avoiding the cost of creating and closing connections.

Use Spring Boot's JDBC template to connect to databases by adding the Spring Boot starter JDBC and H2 dependencies, auto-configuring the data source and enabling row mapping with RowMapper.

Explore jdbc template and named parameter jdbc template in Spring for insertion, update, delete, and query operations, with prepared statements, result set mapping, and Spring Boot data source setup.

Learn to use the JDBC template with H2, configure the property file, and test with Spring Boot to run a select query and fetch a car id by parameterized query.

Learn how Spring Boot and JPA Hibernate enable ORM to persist Java objects as database tables via entities, primary keys with generated values, relationships, and CRUD annotations.

Access data with Hibernate in Spring using the entity manager and JPA annotations; configure Hibernate with Spring Boot properties, map entities, and control fetch, cascade, and DDL behavior.

Learn to build data access with JPA and Hibernate in a Spring Boot app, using an H2 in-memory database, entity mappings, a repository, and basic REST endpoints for cars.

Learn how lazy loading with spring data jpa and hibernate optimizes data access by loading only needed related objects, balancing eager and lazy fetch strategies and handling lazy initialization.

Explore transaction rollback in JPA Hibernate within Spring Boot, including how checked and unchecked exceptions influence commit or rollback and how rollbackFor customizes rollback behavior.

Explore Spring transaction propagation rules and how a service method decides to start or continue a transaction, covering all seven types: required, requires new, nested, supports, not supported, mandatory, never.

Explore read-only transaction attributes in MVCC databases such as Oracle, PostgreSQL, and MySQL, and see how read-only isolation prevents updates, offers serialized protection, and avoids lock contention.
