org.glassfish.jersey.serveur.de modèle.ModelValidationException: Validation de la demande de ressources de modèle a échoué lors de l'initialisation de l'application

Je suis le développement de printemps de démarrage microservices exemple à partir du lien: https://dzone.com/articles/spring-boot-creating. Dans ce projet, j'ai simplement mis à jour le parent de dépendance à sa dernière version et d'autres fichiers de code sont inchangés. J'ai affronté le message d'erreur suivant lorsque je clique sur http://localhost:8080/order?idCustomer=2&idProduct=3&montant=4

Double Possible de MULTIPART_FORM_DATA: Pas d'injection de source d'information pour un paramètre de type public javax.ws.rs.de base.Réponse de

InformationsquelleAutor | 2016-09-09

J'ai été en mesure de résoudre ce problème. vous avez besoin de faire quelques changements dans le mappage d'URL de la requête. Je me demande comment le code dans le bloc fonctionne sans erreur.

Selon ma compréhension, une cause possible est que vous avez deux ou plus applicable mappages pour que les URL d'appel. CustomerRest.java et ProductRest.java les deux ont été cartographiés à /.

@Path("/")

@Path("/")

La Jersey ont aucun moyen de savoir quelle méthode est censée être appelé et donne cette erreur.

Vous avez besoin de corriger les fichiers suivants:
OrderRest.java

@Named
@Path("/")
public class OrderRest {
private long id = 1;
@Inject
private RestTemplate restTemplate;
@GET
@Path("order")
@Produces(MediaType.APPLICATION_JSON)
public Order submitOrder(@QueryParam("idCustomer") long idCustomer,
@QueryParam("idProduct") long idProduct,
@QueryParam("amount") long amount) {
Customer customer = restTemplate.getForObject("http://localhost:8080/customer/getCustomer?id={id}", Customer.class, idCustomer);
Product product = restTemplate.getForObject("http://localhost:8080/product/getProduct?id={id}", Product.class,idProduct);
Order order = new Order();
order.setCustomer(customer);
order.setProduct(product);
order.setId(id);
order.setAmount(amount);
order.setOrderDate(new Date());
id++;
return order;
}
}

Dans CustomerRest.java - utilisez cette

@GET
@Path("/getCustomer")
@Produces(MediaType.APPLICATION_JSON)
public Customer getCustomer(@QueryParam("id") long id) {
Customer cli = null;
for (Customer c : customers) {
if (c.getId() == id)
cli = c;
}
return cli;
}

Dans ProductRest - utilisez cette

@GET
@Path("/getProduct")
@Produces(MediaType.APPLICATION_JSON)
public Product getProduct(@QueryParam("id") long id) {
Product prod = null;
for (Product p : products) {
if (p.getId() == id)
prod = p;
}
return prod;
}

Voici le résultat:
org.glassfish.jersey.serveur.de modèle.ModelValidationException: Validation de la demande de ressources de modèle a échoué lors de l'initialisation de l'application

Essayer si vous avez de la méthode post: j'ai fait face à la même question. Mais mon cas d'utilisation a été peu différent dans ce POST de la méthode de passage 2 params c'est pourquoi il lance la même exception.
- Est-ce censé être une réponse?
