ObjectMapper ne peut pas mapper les variables de la classe interne

Question

ObjectMapper mapper = new ObjectMapper();

try {

}

En mode débogage, la réponse de chaîne dans objectMapper montre la réponse correcte, réponse de chaîne dans attractionMainResponse donnant un succès, mais ne peut pas mapper l'attractionDetailModel, donnant null.

Answer 1

S'agit-il d'un ObjectMapper Jackson? Est-il possible de créer un exemple plus petit, ce qui rend plus facile de donner une solution.
