Spring Boot has become one of the most popular Java frameworks because it simplifies development, speeds up delivery, and enhances security. Built on the Spring Framework, it eliminates heavy configuration with opinionated defaults and embedded servers, letting developers focus on business logic instead of setup.
It’s also microservices-ready, making it ideal for cloud-native applications. With tools like Spring Cloud and Actuator, teams gain built-in monitoring, health checks, and scalability features out of the box.
Security is where Spring Boot truly stands out. Through Spring Security, it provides authentication (username/password, OAuth2, JWT), role-based access control, and protection against CSRF, XSS, and session attacks. Passwords are stored securely using BCrypt, and endpoints are locked down by default—ensuring apps start secure.
For startups and enterprises alike, Spring Boot offers the perfect balance of speed, flexibility, and enterprise-grade security.
