Chemin upload fichier vers bdd
Bonjour,
Dans le cadre d'un site web je teste l'upload d'un fichier vers ma BDD.
Lorsque je suis en local tout marche nickel, mais quand je met à jours mon site sur heroku ( bdd hebergée par amazom pour heroku) cela ne marche pas.
La raison : dans mon code java, je demande à l'image d'être stockée en local sur mon ordinateur.
Mon problème est le suivant : quel chemin dois indiquer, et que devrais je modifier dans ma bdd pour que mon fichier s'upload sur la bdd ?
J'ai déjà fais de recherche mais je trouve pas de reponse à mon cas précis.
J'utilise Thymeleaf dans un maven project.
J'ose espérer que la solution est vraiment simple, seulement c'est bien frustrant de ne pas la trouver :/
Merci pour votre aide,
Bonne soiree :)
Je joins ici la page de test html que j'ai fais pour m'afficher mes images, ainsi que les servlet et methodes java.
