Return null sur ma ressource

**DiR95** · 01/01/2016, 12h33

Bonjour tous le monde,

J'accède à une ressource (http://localhost:8080/CountryCode/v1/e212/33) seulement dans mon logger j'ai un return null alors que je retourne bien quelque chose.

Je vous mets l'intégralité du code, je sais que ça va être long mais j'en suis désolé, je ne vois vraiment pas le problème...

Bonjour tous le monde,

J'accède à une ressource (http://localhost:8080/CountryCode/v1/e212/33) seulement dans mon logger j'ai un return null alors que je retourne bien quelque chose.

Comment tu sais que tu retourne bien quelque chose?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

InputStream ips = servletContext.getResourceAsStream("./WebContent/WEB-INF/countries.txt");

ne marche pas, le chemin correct c'est

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

InputStream ips = servletContext.getResourceAsStream("/WEB-INF/countries.txt");

du coup, exception qui s'en suis sur le NullPointerException, du coup traitement dans ton

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
        } catch (Exception e) {
            logger.info(e.getMessage());
        }

Qui devrais logger un laconique et impossible à voir facilement "INFO: null" dans tes logs.
Donc corrige ton path et corrige ton traitement d'exception. C'est une erreur, pas une simple info, et il faut détailler cette erreur pour la comprendre.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
        } catch (Exception e) {
            logger.error("Could not load country file",e);
        }

Au passage tu devrais éviter les catch (Exception), on ne catche que les Exception que l'on sais spécifiquement traiter et auxquelles on s'attends, le reste est une erreur et devrais remonter plus haut. Exemple:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
        } catch (IOException e) {
            logger.error("IO problem while loading country file, using empty default instead.",e);
        }

Merci à toi pour tes conseils

J'aurai une autre question j'ai créer une ressource /doc pour y faire apparaître mon swagger (en .json) j'ai créer une fonction de lecture getDoc mais je n'arrive pas à l'afficher : (Le fichier spécifié est introuvable)

		return null;
	}

On n'utilise pas FileInputStream pour accéder au contenu d'une webapp, uniquement le Classloader via getRessource ou le ServletContext suivant où se trouve la ressource à charger. Si on a besoin d'un fichier extérieur à la webapp, on fournis le chemin absolu vers le fichier, pas un chemin relatif.

**DiR95** · 02/01/2016, 02h17

Il se trouve dans une webapp. Vous aurez un tuto ou un exemple pour le Classloader ?

**tchize_** · 02/01/2016, 11h10

Il est où exactement ce json? On est dans quelle classe et quel package au niveau de ton code?

Return null sur ma ressource
