javax.xml.bind.UnmarshalException: beklenmeyen öğe. Beklenen öğeler (hiçbiri)

Question

Bu hatayı alıyorum, bir dizeyi unmarshalling. JAXB kullanarak Java dosyaları oluşturdum.

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

Yığın izleme:

Answer 1

bir XML Şeması bir JAXB bir model oluşturmak, küresel elemanlar o adlandırılmış karmaşık ty karşılık pes, ObjectFactory sınıfındaki bir oluşturma yönteminde @XmlElementDecl ek notu olarak yakalanan meta verilere sahip olacaktır. DocumentType sınıfında JAXBContext'u oluşturduğunuz için, bu meta veriler işlenmiyor. JAXB modelinizi bir XML Şeması'ndan oluşturduysanız, gerekli tüm meta verilerin işlendiğinden emin olmak için oluşturulan paket adı veya ObjectFactory sınıfında JAXBContext'u oluşturmalısınız.

Örnek çözümü: Alternatif

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

Answer 2

Eğer DocumentType sınıfını kullanarak ısrar etmek istiyorum. Sonra, aşağıdaki notu DocumentType sınıfınızın üstüne ekleyebilirsiniz.

@XmlRootElement(name="document") 

Not: String değeri "document" xml mesajın kök etiketinin adını belirtir.

Answer 3

Bu hatanın nedenlerinden biri, jdk uygulamasının jaxb uygulamasının kullanılmasıdır. Böyle bir sorunun neden oldukça basit xml ayrıştırma durumlarında görünebileceğinden emin değilim. Bir kamu maven deposundan JAXB kütüphanesinin son sürümünü kullanabilir:

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