javax.xml.bind.UnmarshalException: elemento inatteso (uri: "", locale: ""). Gli elementi previsti sono

Question

Puoi trovare un sacco di domande come questa in questo sito ma nessuna ha risolto il mio problema.

Questo è il mio 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> 

Ho creato la classe JAXB usando il compilatore XJC e il file creato è come:

// 
// This file was generated by the JavaTM Architecture for XML Binding(JAXB) Reference Implementation, vJAXB 2.1.10 in JDK 6

Ho ricevuto questo errore:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances> 

Per favore aiuto.

Answer 1

Sembra che la classe creato da JAXB non contiene le informazioni namespace:

@XmlType(name = "", propOrder = { 
    "lookupParameters" 
}) 

Ho il sospetto che causa questo errore, semplicemente perché non si aspetta namespace:

javax. xml.bind.UnmarshalException: elemento inatteso (uri: "http://www.pqr.com/awd/rest/v1", locale: "lookupInstances"). elementi attesi sono < {} lookupInstances>

io non sono sicuro perché la classe generata manca di questa informazione, ma vorrei iniziare con l'aggiunta manualmente per verificare che questo è il problema:

@XmlType(name = "", namespace= "http://www.pqr.com/awd/rest/v1", propOrder = { 
    "lookupParameters" 
}) 

Answer 2

Ho cambiato la classe jaxb cambiando xsd e ora funziona.

Answer 3

seguito alcune informazioni che dovrebbe aiutare:

XML

seguito è una parte del vostro XML. Una cosa da notare è l'attributo xmlns. Questo è un attributo speciale e fa riferimento alla qualifica dello spazio dei nomi all'interno del documento XML.

<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'> 
    <lookupParameters/> 
</lookupInstances> 

Di seguito è un'altra versione del XML con la stessa qualifica namespace:

<abc:lookupInstances xmlns:abc='http://www.pqr.com/awd/rest/v1' name='LKIMGR'> 
    <abc:lookupParameters/> 
</abc:lookupInstances> 

Quando si rimuove il xmlns attribuiscono la qualifica di namespace viene rimosso. Il documento sottostante non è equivalente ai due sopra.

<lookupInstances name='LKIMGR'> 
    <lookupParameters/> 
</lookupInstances> 

tuo errore

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances> 

Questo errore indica che non è stato mappato in modo corretto la qualificazione dello spazio dei nomi.

Mappatura del Namesapce qualificazione in JAXB

Namespace qualifica in JAXB è fatto con il livello del pacchetto @XmlSchema annotazione. Le annotazioni a livello di pacchetto vanno a package-info.java. Di seguito è la fonte completa per questa classe. Se hai già un file sorgente package-info.java assicurati che sia compilato e pacchettizzato con il resto delle tue classi.

@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; 

XML Schema

Se si sta generando il vostro modello da uno schema XML assicurarsi questa qualifica spazio dei nomi sia correttamente definire lì. Sembrerà:

<?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> 

Answer 4

Prima di tutto è necessario controllare il file XML di input. Assicurarsi che l'XML di input dovrebbe avere lo stesso elemento radice del file XSD (che è stato utilizzato per creare le classi JAXB) Quindi riprova di seguito XML, E funziona bene :)

<?xml version='1.0' encoding='UTF-8' standalone='yes'?> 
<lookupInstances name='LKIMGR'> 
<lookupParameters> 
<lookupParameter name='businessArea'>PQAA</lookupParameter> 
<lookupParameter name='MEMBERNUMBER'>ANTHONY1900</lookupParameter> 
</lookupParameters> 
</lookupInstances> 

Answer 5

Change

@XmlRootElement(name = "lookupInstances") 

a

@XmlRootElement(namespace = "http://www.pqr.com/awd/rest/v1", name = "lookupInstances") 

Answer 6

@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; 

: questo componente e ve RY importante per le classi generate da JAXB, in particolare lo elementFormDefault = XmlNsForm.QUALIFIED non verrà automaticamente aggiunto da JAXB.

Grazie Blaise, la tua risposta mi ha aiutato.
