En otras palabras vemos
que llegue todo en regla.
- Se va a apollar en un
paquete de excepciones para
lanzar los try catch.
resources es la capa de presentacion
aquí se contemplan todas las vistas
tomando en cuenta lo que devuelve
mi api rest (para este caso devolvemos
JSONs, entonces los json son nuestras
vistas de procesar un resultado).
cabe aclarar que esta vista no sera
humana, sino que sera para otra
maquina.
