## Overview

Develop production-ready Spring Boot applications with proper annotation-based configuration, dependency injection, REST controllers, JPA data persistence, service layers, and security implementation following Spring conventions.

## When to Use

- Building Spring Boot REST APIs
- Implementing service-oriented architectures
- Configuring data persistence with JPA
- Managing dependency injection
- Implementing Spring Security
- Building microservices with Spring Boot

## Quick Start

Minimal working example:

```xml
<!-- pom.xml -->
<project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example</groupId>
    <artifactId>api-service</artifactId>
    <version>1.0.0</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.1.0</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Use dependency injection for loose coupling
- Implement service layer for business logic
- Use repositories for data access
- Leverage Spring Security for authentication
- Use @Transactional for transaction management
- Validate input in controllers
- Return appropriate HTTP status codes
- Use DTOs for request/response mapping
- Implement proper exception handling
- Use Spring's @Async for async operations

### ❌ DON'T

- Put business logic in controllers
- Access database directly in controllers
- Store secrets in configuration files
- Use eager loading for large relationships
- Ignore transaction boundaries
- Return database entities in API responses
- Implement authentication in controllers
- Use raw SQL without parameterized queries
- Forget to validate user input
