Explore dependency injection in Spring by building a user service that uses an email service via constructor-based injection, wired through an application context XML bean configuration.

Explore how Spring auto-wiring simplifies dependency injection by automatically wiring beans using by-name, by-type, constructor, or auto-detect modes, while noting limitations like overriding and primitive types.

Explore Spring auto-wiring in this example, covering default, by-name, by-type, and constructor injection with email and Twitter message services.

Explore Spring Boot and the Spring Framework, including modular components for building Java web apps, the benefits, and a comparison of Spring Boot 2 and 3 with Spring MVC.

Explore how the Spring framework provides the core container and dependency injection, data access and web modules, and how Spring Boot simplifies configuration for quick Java web app development.

Spring Boot builds on the Spring Framework with auto-configuration, starter dependencies, embedded servers and Maven, enabling quick web app development and configurable deployment.

Discover why Spring Boot accelerates web development with flexible, annotation-driven configuration, starters for easy dependency management, and an embedded servlet container with auto-configuration.

Explore the history of spring boot and spring, tracing major version milestones from spring 1.0 (2004) to spring boot 3 (2022).

Explore features of Spring Boot 2 and 3, including embedded servers with Tomcat and Jetty, starters, configuration, actuator endpoints, reactive support, Java 17, GraalVM native images, and Jakarta EE migration.

Compare Spring Boot and Spring MVC, highlighting Spring Boot's stand-alone, zero-configuration setup and automatic configuration, versus Spring MVC's manual configuration and deployment descriptor needs for web applications.
