Spring Boot Security Tutorial 🛡️

Spring Boot Security is a powerful framework for building secure applications with minimal boilerplate code. It simplifies authentication, authorization, and secure API development by integrating with Spring Security's robust features. Below are key concepts and practical steps to get started:

📌 Core Features

• Authentication: Supports username/password, OAuth2, and JWT tokens
• Authorization: Role-based access control (RBAC) and method-level security
• Secure APIs: HTTPS enforcement and CSRF protection
• Customization: Easily extendable for business-specific security needs

🧱 Quick Start Guide

1. Add dependency to pom.xml:

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-security</artifactId>
   </dependency>
   

2. Create a security configuration class:

   @Configuration
   @EnableWebSecurity
   public class SecurityConfig extends WebSecurityConfigurerAdapter {
       // Configure authentication and authorization here
   }
   

3. Implement user service for authentication logic

🔐 Advanced Topics

• Password Encoding: Use BCryptPasswordEncoder for secure storage
• OAuth2 Integration: Configure client credentials and token endpoints
• Custom Filters: Extend security behavior with pre/post request processing
• Remember-Me Feature: Enable persistent login sessions
