What is Spring Boot?
- A framework for building applications in Java programming language.
- Facilitates easy creation of standalone, production-grade Spring-based applications.
- Simplifies creation, setup, and configuration of Spring applications.
Comparison with Spring
- Pre-Spring Boot: Required manual configurations for Spring applications.
- Spring Boot: Automates most of this setup, reducing boilerplate code and manual configurations.
- Core Advantage: Takes convenience to the next level by simplifying setup and configuration further.
Benefits of Spring Boot
- Auto-Configuration: Eliminates manual setup by providing embedded Tomcat server and other necessary components.
- Standalone Applications: Independent of external servers/infrastructure. Embed server within Spring Boot applications.
- Simplifies deployment steps significantly.
Spring Boot Features
- Spring Boot Application Annotation: Simplifies application context setup with single annotation.
- Embedded Web Server: No need for external Tomcat. Simplifies deployment.
- Automatic Component Scanning: Configures components automatically.
Beans and Application Context
- Beans: Reusable objects within the Spring context. Configured once and used throughout the application.
- Application Context: Manages beans; provides required beans when requested in code.
- Spring Boot automates the configuration of the application context.
Requirements
- IntelliJ and Java Installation: Make sure IntelliJ and Java are installed on your system.
