Spring Framework and Hibernate with MVC Course

Configure Spring Boot across environments by managing properties from the command line, JVM parameters, OS environment variables, and classpath files, with active profiles guiding YAML or properties files.

Use Spring profiles to configure environment properties for development and production, with an active profile def and a dev properties file that overrides management endpoints via application properties like management.web.exposure.

Explore yaml configuration in spring boot, use yaml as an alternative to properties, apply spring profiles, and bind yaml properties to typed Java config classes with configuration properties.

Configure and customize logging in Spring Boot using Logback, with starters and Maven, control levels from trace to fatal, and choose outputs and formats via XML, Groovy, YAML, or JSON.

Configure spring boot logging by editing application.properties, set logging levels (info, debug, trace), and route logs to a file path, while bootstrapping the app and verifying actuator health.

Explore model-view-controller architecture and enterprise project structure, including front controllers, routing, and the layered UI, service, and data access components for scalable web applications.

Create your first rest controller in spring by building a car wash controller with @RestController and @RequestMapping, returning a JSON list of cars and testing with a get request.

Explore Java server pages as a front-end technology, using servlet APIs to render dynamic content, and configure Spring Boot to resolve JSP views with a war packaging strategy.

Disable the default white label error page in Spring Boot and customize it with templates. Use properties, YAML, or controller overrides to handle codes such as 400 and 500.

Activate cache busting by enabling spring.resources.chain.content.enable in the application properties. Then test with a car washer controller and a cache busting page to observe the hash changing with content updates.

Explore representational state transfer and how Spring Boot enables building rest-based web services with a RestController, request mapping, request body, path variable, and ResponseEntity using JSON or XML.

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.

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.

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 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.

Activate security in Spring Boot by adding the Spring Boot security starter, then test the default configuration with the auto-generated login credentials.

Configure spring boot security by extending WebSecurityConfigurerAdapter, overriding configure methods, redirecting unauthenticated users to login page, and defining a user with username user and password password while permitting static resources.

Customize Spring Boot web security by creating a security configuration class, overriding configure, enabling form login, and securing endpoints such as actuator health.

Configure logout in Spring Security, using post method logout with CSRF protection, invalidate the session, clear the security context and cookies, and customize via web security configuration.

Configure logout in a spring boot app with gsp, add dependencies, set mvc view prefix and suffix, and build a post logout form with csrf to redirect to login.

Build a custom login page using form-based authentication with JSP, including a login form, a tag library, and error handling. Configure security and test login success and failure scenarios.

Enable remember me in spring boot security by using a checkbox to issue a remember me cookie with username and expiration, plus password and a secret key.

Practice configuring remember me in the login form and security configuration, inject the user details service, and test persistent login across browser restarts using the remember me cookie.

Configure H2 in spring security by enabling access to the H2 console. Disable CSRF protection and allow framing to load in a browser for embedded and server modes.

Explore how Spring Security with Spring Boot handles user data such as users, roles, and groups, using jdbc authentication and queries by username for users, authorities, and group authorities.

Manage user data in an H2 database by creating users and authorities tables, bootstrapping the app, and loading users from the data source to authenticate through the security configuration.

Enable or disable unit and integration tests using Spring's if profile value based on environment or system variables, at class or method level.

Create a Spring Boot test class with four annotations, inject a bean to access property data, and show that the default profile is active while DEVE activates dev properties.

Send emails in spring boot using the java mail sender and spring boot starter mail, configuring spring.mail.host on localhost and testing with a fake smtp server.

Master scheduling in Spring Boot by using cron expressions and the scheduled annotation to trigger tasks. Configure fixed rate, fixed delay, and time zone, plus initial delay, for flexible timing.
