Getting Started with Spring Boot
Spring Boot Basics
Spring Boot is an extension of the Spring framework that simplifies the process of building and deploying standalone, production-ready Spring applications. It leverages convention over configuration, allowing developers to set up applications quickly with minimal setup and boilerplate code. Spring Boot uses various embedded servers such as Tomcat or Jetty, which means that applications can run independently without an external server. It provides a range of features, including auto-configuration, a robust dependency management system, and a variety of built-in endpoints for monitoring and management through Spring Actuator. With Spring Boot, developers can easily create RESTful APIs and microservices, making it a popular choice for modern application development.

1 - Introduction to Spring Boot: Understand what Spring Boot is and its purpose in simplifying the development of Spring applications by providing convention over configuration.
2) Getting Started: Set up your environment for Spring Boot development. This includes installing Java, Spring Boot tools, and IDEs like IntelliJ or Eclipse.
3) Creating a Spring Boot Application: Learn how to create a new Spring Boot project using Spring Initializr, which allows you to select dependencies and generate a starter project.
4) Understanding the Project Structure: Explore the typical directory layout of a Spring Boot application, including `src/main/java`, `src/main/resources`, and configuration files.
5) Spring Boot Annotations: Familiarize yourself with key annotations such as `@SpringBootApplication`, `@RestController`, `@RequestMapping`, and how they simplify your code.
6) Dependency Management: Learn about Maven or Gradle, the build tools commonly used with Spring Boot, to manage project dependencies easily.
7) Building RESTful Web Services: Create REST APIs using Spring Boot, including handling HTTP requests and returning JSON responses.
8) Configuration Properties: Discover how to configure your application using the `application.properties` or `application.yml` files to manage environment specific settings.
9) Profile Management: Understand how to use Spring profiles to manage different configurations and beans for various environments (development, testing, production).
10) Error Handling: Learn how to handle exceptions gracefully in your Spring Boot application using `@ControllerAdvice` and custom error responses.
11) Database Integration: Explore how to connect your Spring Boot application to a database using Spring Data JPA, including setting up entities and repositories.
12) Entity Relationships: Understand how to model relationships between entities, such as One to One, One to Many, and Many to Many using JPA annotations.
13) Spring Boot Actuator: Discover how to use Spring Boot Actuator to monitor and manage your application by exposing operational endpoints.
14) Security Basics: Get an introduction to securing your Spring Boot application using Spring Security, including basic authentication and authorization.
15) Testing Spring Boot Applications: Learn how to write unit tests and integration tests for your Spring Boot application using JUnit and Mockito.
16) Deployment Strategies: Understand different deployment techniques for Spring Boot applications, including running as a standalone jar, deploying to a cloud platform, or using Docker.
17) Building Microservices: Explore the microservices architecture and how Spring Boot facilitates building scalable and maintainable microservices.
18) Best Practices and Guidelines: Familiarize yourself with best practices for developing robust Spring Boot applications, such as logging, exception handling, and adhering to coding standards.
This comprehensive overview of Spring Boot basics serves as a solid foundation for students looking to gain practical knowledge in this powerful framework.
