J'utilise le code suivant pour désérialiser un objet JSON:JSON désérialisation fonctionne de test, mais pas de servlet
System.out.println("Trying to deserialize the following string: " + jsonString);
DRRequest elements = JSONMapper.objectMapper.readValue(jsonString, DRRequest.class);
System.out.println("Done, the resulting object is: " + elements);
Quand j'appelle le code du test, il fonctionne correctement et je reçois la sortie suivante:
Trying to deserialize the following string: { "start_time":"2015-10-19T13:00:00.000+02:00", "interval":900,"unit":"kW","target_values": [50.3253179, 45.15539599955082, 56.13061499595642, 68.14941400289536, 65.79, 63.140625, 47.14074699580669, 28.16027800738811, 61.14758299291134],"prosumers_primary":[ "Pr_1","Pr_4","Pr_7","Pr_1"],"prosumers_secondary":[ "Pr_2","Pr_3","Pr_8","Pr_11","Pr_16"]}
Done, the resulting object is: [email protected]
Mais lorsque je tente d'utiliser le code du servlet, je reçois l'erreur suivante:

Quelqu'un peut-il m'aider à comprendre ce qui cause l'exception, comment y remédier?

Je pense qu'il manque la dépendance joda dans votre chemin de classe. –
Il semble que votre 'JSONMapper.objectMapper' ait une configuration différente lors de l'exécution du test que du code de production –
@AdamSiemion: où serait cette configuration? J'ai les fichiers de configuration suivants dans le projet, et aucun ne semble avoir quelque chose de similaire ... 'src/main/resources/localhostTestConfig.cfg.xml src/main/resources/logback.xml src/main/webapp/WEB-INF/web.xml src/main/java/com/hibernate.cfg.xml' Notez que j'essaie d'exécuter un projet que quelqu'un d'autre a écrit, donc je n'ai pas une bonne connaissance de la configuration – user000001
