Explore dependency injection and inversion of control using the Spring IoC container to manage dependencies, reduce tight coupling, and simplify configuration with constructors, setters, and factories.

Update a product using Spring Data and JPA by finding it via type, then updating its fields and saving the entity. Hibernate updates the existing record using the primary key.

Create a Spring Boot REST API with a product entity, a JPA repository, and CRUD operations via a REST controller and request mappings, backed by an H2 database.

Learn how to post a product to a Spring REST API, using a request body and JSON data, and persist it to the database via a post endpoint at api/products.

Implement a put endpoint with Spring REST that updates a product by id using a JSON request body, saving changes to the repository and returning the updated product.

Implement a delete endpoint in Spring REST to remove a product by id. Find and delete the entity in the repository, returning 200 with no content.

Explore rest api elements in spring, including rest controller, request mapping, path variable, and jpa repository, and see how get, post, put, and delete endpoints consume and produce json.

Refactor the rest api to improve maintainability by implementing controller advice for exception handling, logging user actions, moving logic to a product service, and using a dto for errors.

Refactor the rest api by moving the controller logic to a service, creating a void delete method using the id, and adding logging and exception handling.

Learn to call Spring endpoints programmatically using RestTemplate, set up a RestTemplate bean, wire it with autowired, and perform get requests against a rest api and repository application.

Learn how to build a Eureka server and register microservices, register apps with Eureka, and use Netflix Feign client for simplified inter-service REST calls in a Spring Cloud environment.

Develop a Feign client to call a REST API through Eureka discovery, using an interface annotated as a Feign client and a simple POJO to map the response.

Break the project into building blocks—from components to basic data models and persisting data to a database, then build models, repositories, services, and controllers with clear request mappings.

Review RESTful APIs, HTTP methods, and response codes; build a Spring REST API with a model, service, and controller; refactor for maintainability and explore RestTemplate, Feign, and Eureka.

Build a full-featured Spring Boot web application to manage products, using Spring Data and Spring REST, with a UI built on Bootstrap to list, create, and edit products.

Bootstrapping the application, this lecture creates a Spring project with web and JPA dependencies, configures an H2 database, and implements a data loader, entity, and repository.

Build an index page with a reusable header and a Bootstrap navigation using HTML5 and CSS3, showcasing home, products, create product, and a jumbotron.

Create a product page by building a controller with a get mapping, a bound product form, and a post to /products that saves via the repository and redirects to index.

Create a products listing page at /products and render a table showing id, name, description, type, category, and price, using th:if and th:each with repository findAll to supply data.

Add an edit button to the product table, link it to /products/edit with the product id, fetch the product in the edit controller, populate the form, and update the price.

Add a delete button to the products table, implement a Spring Boot delete method with path and id, and redirect to the updated products page, and style the navigation bar.

Learn to build a spring boot app with spring data and web, load two initial products, and manage them via a bootstrap-thymeleaf ui with create, edit, and delete.

Outline components and design considerations, then implement a CRUD application in Spring from scratch or customize the shared application.

This section reviews building a web app with spring boot and spring rest, implementing CRUD operations and a bootstrap UI. It introduces extras like live reload, lombok, actuator, and swagger.

Learn to speed development with Spring DevTools and live reload, enabling hot swapping and instant changes in the browser for your Spring applications.

Learn to document a restful API with Swagger, configure Swagger 2 via Springfox, supply API info and docs path, and explore the interactive Swagger UI for your controllers.

Explore Spring actuator to monitor and interact with your application through pre-built endpoints, customize endpoints, and control environments and mappings via application properties for real-time insights.

Enable Spring scheduler in a Spring Boot app with @EnableScheduling and @Scheduled to run actions. Use initial delay, fixed delay, and fixed rate, and note data cannot be persisted.

Explore project Lombok to remove boilerplate by using annotations like @Data, which auto-generates getters, setters, toString, equals, hashCode, and with @AllArgsConstructor and @NonNull for constructors and null checks.

Build a Spring Boot email client that templates and delivers HTML emails with Thymeleaf, using a mail sender, template engine, and a command line runner to send a demo message.

Leverage Spring dev tools for instant updates with a plug-in to boost your development workflow. Use Swagger for API documentation, Spring Actuator metrics, Lombok, and Time Wave email templates.

Explore the spring ecosystem, from spring and spring boot fundamentals to extras like actuator and swagger, and see how spring powers cloud native architectures used by Netflix and others.

Celebrate your progress as you finish this spring development marathon and follow for updates on the upcoming course on Macra services and cloud development with spring.
