# Introduction to Spring Boot
Spring Boot is one of the most popular Java frameworks used for building modern web applications, REST APIs, and microservices. It is built on top of the Spring Framework and simplifies Java development by reducing configuration and setup time.
Developers use Spring Boot to create fast, secure, scalable, and production-ready applications with minimal code.
---
# Why Learn Spring Boot?
Spring Boot is widely used in the software industry because it offers:
* Easy project setup
* Embedded servers like Tomcat
* Fast application development
* REST API support
* Database integration
* Microservices architecture support
* Security features
* Cloud deployment support
Many companies such as Amazon, Netflix, and Google use Spring Boot-based systems for scalable backend services.
---
# Features of Spring Boot
## 1. Auto Configuration
Spring Boot automatically configures your project based on dependencies present in the application.
Example:
If MySQL dependency is added, Spring Boot automatically sets up database configurations.
---
## 2. Embedded Server
You do not need to install external servers separately.
Supported servers:
* Tomcat
* Jetty
* Undertow
Run application using:
```bash
mvn spring-boot:run
```
---
## 3. Starter Dependencies
Spring Boot provides starter packages to simplify dependency management.
Examples:
* spring-boot-starter-web
* spring-boot-starter-data-jpa
* spring-boot-starter-security
---
## 4. REST API Development
Spring Boot is excellent for creating RESTful APIs.
Example:
```java
@RestController
public class HelloController {
@GetMapping("/")
public String hello() {
return "Hello Spring Boot";
}
}
```
---
## 5. Production Ready Features
Spring Boot provides:
* Monitoring
* Health checks
* Metrics
* Logging
Using:
```xml
spring-boot-starter-actuator
```
---
# Spring Boot Architecture
Main layers:
1. Controller Layer
2. Service Layer
3. Repository Layer
4. Database Layer
Flow:
Client → Controller → Service → Repository → Database
---
# Creating Your First Spring Boot Project
## Step 1: Install Requirements
You need:
* Java JDK
* Maven
* IDE like IntelliJ IDEA or Visual Studio Code
---
## Step 2: Create Project
Use the official Spring Initializr:
[Spring Initializr](https://start.spring.io?utm_source=chatgpt.com)
Choose:
* Project: Maven
* Language: Java
* Dependencies: Spring Web
---
## Step 3: Run the Application
Main class:
```java
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
```
Run:
```bash
mvn spring-boot:run
```

# Spring Boot Project Structure
```text
src
└── main
├── java
│ └── com.example.demo
│ ├── controller
│ ├── service
│ ├── repository
│ └── model
└── resources
├── application.properties
└── static
```
---
# Database Integration
Spring Boot supports databases like:
* MySQL
* PostgreSQL
* MongoDB
Example MySQL configuration:
```properties
spring.datasource.url=jdbc:mysql://localhost:3306/demo
spring.datasource.username=root
spring.datasource.password=password
```

# Spring Boot Annotations
Important annotations:
| Annotation | Purpose |
| ---------------------- | --------------------------- |
| @SpringBootApplication | Main application annotation |
| @RestController | Creates REST controller |
| @GetMapping | Handles GET requests |
| @PostMapping | Handles POST requests |
| @Service | Service layer |
| @Repository | Database layer |
| @Autowired | Dependency injection |
