javax.xml.bind.UnmarshalException: elemento inaspettato. Gli elementi previsti sono (nessuno)

Ricevo questo errore, mentre non eseguo il riarmo di una stringa. Ho creato file Java usando JAXB.javax.xml.bind.UnmarshalException: elemento inaspettato. Gli elementi previsti sono (nessuno)

JAXBContext jaxbContext = JAXBContext.newInstance(DocumentType.class); 
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); 
// Input string posted below 
DocumentType dType = (DocumentType) unmarshaller.unmarshal(new StringReader("input string"));

traccia stack:

Quando si genera un modello di JAXB da uno schema XML, elementi globali che corrispondono a nome complesso ty pes avrà quei metadati catturati come annotazione @XmlElementDecl su un metodo di creazione nella classe ObjectFactory. Poiché stai creando JAXBContext solo sulla classe DocumentType, questi metadati non vengono elaborati. Se il modello JAXB è stato generato da uno schema XML, è necessario creare lo JAXBContext sul nome del pacchetto generato o sulla classe ObjectFactory per garantire che tutti i metadati necessari vengano elaborati.

soluzione Esempio:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class); 
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

funziona bene. unmarshaller.unmarshal() restituirà JAXBElement invece di DocumentType. Chiama getValue() per ottenere l'oggetto spostato. – rwitzel

Nel mio caso, chiamare l'elemento radice importato richiesto 'unmarshaller = context.createUnmarshaller(); finale Oggetto object = unmarshaller.unmarshal (nuovo file ("percorso/a/data.xml")); finale DocumentType cd = (DocumentType) oggetto; ' – CodeMed

Secondo passo è simile al seguente:.' DocumentType doc = (. (JAXBElement ) jaxbContext.createUnmarshaller() unmarshal ( inputStream)) getValue(); ' –

In alternativa, se si vuole persistere nel utilizzando la classe DocumentType. Quindi è possibile aggiungere la seguente annotazione sulla classe DocumentType.

@XmlRootElement(name="document")

Nota: il valore String "document" si riferisce al nome del tag radice del messaggio XML.

Grazie, amico. Dopo aver cercato ore per una soluzione in questa situazione, @XmlRootElement ha risolto il problema. Mi chiedo perché questo comportamento dovrebbe essere così. Ha davvero senso forzare questa annotazione in un processo di smantellamento? – Miere

@Miere Ora che ci penso. Nel mondo dei servizi Web, lo stile RPC fornisce automaticamente un nodo wrapping, in cui i servizi Web in stile documento richiedono una dichiarazione esplicita. Quindi, è sempre stata un'area di discussione. – bvdb

Sto usando xjc in jdk1.6.0_45 per generare POJO da XSD. Manca il root POJO generato da xjc @XmlRootElement (name = "RootName").Aggiungi questa linea in cima manualmente e unmarshal ha successo. – oraclesoon

Uno dei motivi di questo errore è l'utilizzo dell'implementazione jaxb da jdk. Non sono sicuro del motivo per cui un simile problema possa apparire in semplici situazioni di analisi di xml. È possibile utilizzare la versione più recente della libreria JAXB da un repository Maven pubblico:

http://mvnrepository.com

<dependency> 
    <groupId>javax.xml.bind</groupId> 
    <artifactId>jaxb-api</artifactId> 
    <version>2.2.12</version>
