Comment résoudre MessageBodyWriter introuvable pour le type de support = erreur multipart / form-data

Comment configurer le fournisseur pour une publication multi-formulaire simple. Toute suggestion/indication serait très appréciée.

Eh bien, la lecture de la documentation n'a pas été utile, mais la lecture du code source des tests d'intégration de jersey l'a été.

Dans l'instance JerseyTest, vous devez remplacer la méthode configureClient et passer la classe MultiPartFeature.

@Override
protected void configureClient(ClientConfig config) {
    config.register(MultiPartFeature.class);
}

Si vous travaillez plutôt du côté client, comme je l'ai été, et que vous utilisez Jersey 1.X, la réponse de angstadt530 sur cette page est ce dont vous avez besoin .

Exception du client Jersey: un rédacteur de corps de message est introuvable

DefaultClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getClasses().add(MultiPartWriter.class);
Client client = Client.create(clientConfig);

est à quoi il ressemble dans mon code, mais l'exemple sur cette page est également excellent.
