About this title

Synopsis

�Sabes Java… pero todav�a no sabes c�mo se construye un backend “de verdad”?
Java Backend Profesional con Spring Boot 3 es una gu�a pr�ctica orientada a resultados: te lleva desde el proyecto vac�o hasta una API REST completa, siguiendo un enfoque realista y profesional. Sin relleno. Sin promesas m�gicas. Con un proyecto paso a paso que crece cap�tulo a cap�tulo como lo har�a en un entorno de trabajo.
En este libro aprender�s a:

Dise�ar endpoints REST con criterios profesionales (c�digos HTTP, DTOs y contratos).
Persistir datos con Spring Data JPA y mantener un modelo consistente.
Validar entradas y devolver errores claros con un formato est�ndar.
Implementar seguridad con JWT y control de acceso por usuario/rol.
Crear paginaci�n, ordenaci�n y filtrado sin convertir tu API en un caos.
Escribir tests unitarios e integraci�n para evitar regresiones.
Documentar tu API con OpenAPI/Swagger para que cualquiera pueda consumirla.
Preparar el despliegue con Docker y Docker Compose como en un proyecto real.

Ideal para:

Estudiantes y autodidactas que ya dominan lo b�sico de Java.
Programadores que quieren dar el salto a backend con Spring Boot.
Quien necesite un proyecto completo para portfolio o entrevistas.

Si quieres dejar de “probar cosas” y empezar a construir software backend con criterio, este libro es para ti.
