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:

<!-- 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
