javax.xml.bind.UnmarshalException: élément inattendu (uri: "", local: ""). Les éléments attendus sont
Vous pouvez trouver beaucoup de questions comme celle-ci sur ce site, mais aucune n’a résolu mon problème.
Ceci est mon XML:
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<lookupParameters>
<lookupParameter name='businessArea'>PQAA</lookupParameter>
<lookupParameter name='MEMBERNUMBER'>ANTHONY1900</lookupParameter>
</lookupParameters>
</lookupInstances>

J'ai eu cette erreur:
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
S'il vous plaît aider.
Voici quelques informations qui devraient aider:
XML
Vous trouverez ci-dessous une partie de votre code XML. Une chose à noter est l'attribut xmlns. Ceci est un attribut spécial et fait référence à la qualification d'espace de nom dans le document XML.
<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Vous trouverez ci-dessous une autre version du code XML avec la même qualification d’espace de nom:
<abc:lookupInstances xmlns:abc='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<abc:lookupParameters/>
</abc:lookupInstances>
Lorsque vous supprimez l'attribut xmlns, la qualification d'espace de nom est supprimée. Le document ci-dessous n'est pas équivalent aux deux ci-dessus.
<lookupInstances name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Votre erreur
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
Cette erreur indique que vous n'avez pas mappé correctement la qualification d'espace de noms.
Mappage de la qualification Namesapce dans JAXB
La qualification de l'espace de noms dans JAXB est effectuée à l'aide de l'annotation de niveau de package @XmlSchema. Les annotations de niveau de paquet vont dans package-info.Java. Vous trouverez ci-dessous la source complète pour cette classe. Si vous avez déjà un fichier source package-info.Java, assurez-vous qu’il est compilé et empaqueté avec le reste de vos classes.
@XmlSchema(
namespace = "http://www.pqr.com/awd/rest/v1",
elementFormDefault = XmlNsForm.QUALIFIED)
package your_package;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
Schéma XML
Si vous générez votre modèle à partir d'un schéma XML, assurez-vous que cette qualification d'espace de nom est correctement définie. Cela ressemblera à:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.pqr.com/awd/rest/v1"
xmlns="http://www.pqr.com/awd/rest/v1"
elementFormDefault="qualified">
</xs:schema>
Changement
@XmlRootElement(name = "lookupInstances")
à
@XmlRootElement( namespace = "http://www.pqr.com/awd/rest/v1", name = "lookupInstances")
J'ai changé la classe jaxb en changeant le xsd et cela fonctionne maintenant.

Il semble que la classe créée par JAXB ne contienne pas les informations d'espace de nom:
@XmlType(name = "", propOrder = {
"lookupParameters"
})
Je soupçonne que cela cause cette erreur, simplement parce qu'il n'attend aucun espace de nom:
javax.xml.bind.UnmarshalException: élément inattendu (uri: " http://www.pqr.com/awd/rest/v1 ", local: "lookupInstances"). Les éléments attendus sont <{} lookupInstances>
Je ne sais pas pourquoi la classe générée manque de cette information, mais je commencerais par l'ajouter manuellement pour vérifier qu'il s'agit bien du problème:
@XmlType(name = "", namespace= "http://www.pqr.com/awd/rest/v1", propOrder = {
"lookupParameters"
})
@XmlSchema(namespace = "http://www.pqr.com/awd/rest/v1",
elementFormDefault = XmlNsForm.QUALIFIED) package your_package;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
Cette partie est très importante pour les classes générées par JAXB, en particulier elementFormDefault = XmlNsForm.QUALIFIED ne sera pas automatiquement ajouté par JAXB.
Merci Blaise, ta réponse m'a aidé.
Tout d’abord, vous devez vérifier le fichier XML d’entrée. Assurez-vous que le XML d'entrée doit avoir le même élément racine que votre fichier XSD (que vous avez utilisé pour créer les classes JAXb) Essayez donc ci-dessous XML, cela fonctionnera bien :)
