Basic Spring Boot - Everything You Need to Know as a Beginner

What is Spring Boot?

Spring Boot is an advanced version of the Spring framework. It simplifies the development process by reducing the amount of boilerplate code required. Instead of writing extensive configurations, you can use predefined dependencies, making the code easier to read and maintain.

What are Spring Dependencies?

Spring dependencies are essential components of Spring Boot that enhance its functionality. They enable auto-configuration and make the development process more efficient. Additionally, whenever you make changes in your Spring Boot application, it automatically restarts, allowing you to see the updates in real-time on localhost.

Most Used Spring Dependencies

1. Spring Boot Starter Web - For building web applications and RESTful services.
2. Lombok - Reduces boilerplate code for model classes (e.g., Getters, Setters, Constructors).
3. MySQL - A relational database for storing application data.
4. Spring Data JPA - Simplifies database interactions.
5. Spring Security - Provides authentication and authorization features.

What is application.properties in Spring Boot?

The application.properties file in Spring Boot is used to configure various settings within the application. It is located inside the resources folder.

In this file, you can specify properties like:

• Database configuration (username, password, URL)
• Server properties (port number, context path)
• Logging levels and more, depending on the project's requirements.

What is MVC in Spring Boot?

MVC stands for Model-View-Controller architecture. It is a design pattern that helps in organizing code efficiently.

• Model: Represents the entity (database objects).
• View: The UI layer that is displayed to users.
• Controller: The layer where REST APIs are created to handle user requests.

A typical Spring Boot project follows a structured approach by organizing files into packages like:

• Model (Entities)
• Repository (Data access layer)
• Service (Business logic layer)
• Controller (API endpoints)
• Exception Handling (Custom error responses)

We will explore these concepts in the next post. Until then, keep learning and keep enjoying Spring Boot!
