JAXB和EntityResolver

好吧，這是交易。我開始喜歡這個XML文件：JAXB和EntityResolver

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
<ns3:rosApplicationDocument xmlns:ns2="http://ereg.egov.bg/segment/0009-000013" xmlns:ns3="http://ereg.egov.bg/segment/0009-900001" xmlns:ns4="http://ereg.egov.bg/segment/0009-000022">

而且開始喜歡了XSD：

<?xml version="1.0" encoding="utf-8"?> 
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://ereg.egov.bg/segment/0009-900001" xmlns="http://ereg.egov.bg/segment/0009-900001"

<xsd:element name="RosApplicationDocument" type="RosApplicationDocument" />

而解組：

JAXBContext context = JAXBContext.newInstance(c); 
      Unmarshaller um = context.createUnmarshaller(); 
      if (c.equals(RosApplicationDocument.class)) { 
       SchemaFactory schemaFactory = SchemaFactory 
         .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 
       Schema schema = schemaFactory.newSchema(new File(pathToXSD)); 
       um.setSchema(schema); 
       RosApplicationDocument document = (RosApplicationDocument) um 
         .unmarshal(getSource(pathToFile)); 
       RosApplicationDocumentFactory.removeCDATAFromSegments(document); 
       return document; 
      } 

public static SAXSource getSource(String pathToFile) { 
     try { 
      SAXParserFactory parserFactory = SAXParserFactory.newInstance(); 
      parserFactory.setNamespaceAware(true); 
      parserFactory.setValidating(true); 
      SAXParser saxParser = parserFactory.newSAXParser(); 
      XMLReader xmlReader = saxParser.getXMLReader(); 
      xmlReader 
        .setEntityResolver(new RosApplicationDocumentEntityResolver()); 
      InputSource inSrc = new InputSource(new FileReader(pathToFile)); 
      return new SAXSource(xmlReader, inSrc); 
     } catch (SAXException e) { 
      e.printStackTrace(); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (ParserConfigurationException e) { 
      e.printStackTrace(); 
     } 

     return null; 
    }

爲什麼我得到這個異常：[ org.xml.sax.SAXParseException：cvc-elt.1：找不到元素'ns3：rosApplicationDocument'的聲明。]

編輯：

這裏是LSResourceResolver一樣：

public class MyLSResourceResolver implements LSResourceResolver { 

    @Override 
    public LSInput resolveResource(String type, String namespaceURI, 
      String publicId, String systemId, String baseURI) { 
     System.out.println(publicId); 
     System.out.println(systemId); 
     System.out.println(baseURI); 
     System.out.println(namespaceURI); 
     System.out.println(type); 
     return null; 
    } 

}

我將它設置爲出廠，如：schemaFactory.setResourceResolver(new MyLSResourceResolver());

這裏是控制檯輸出：

最後同樣的例外..所以問題不在於xsd

在XML您有：

xmlns:ns3="http://ereg.egov.bg/segment/0009-900001"

所以http://ereg.egov.bg/segment/0009-900001應該是模式的默認命名空間，但我在您發佈的示例代碼中沒有看到它聲明。

此外，該模式中的元素聲明RosApplicationDocument而文件rosApplicationDocument（小寫）在

編輯XML模式是缺少幾行...對不起 – dsthetics

您有名稱的另一個問題：第一個字母在模式中是大寫字母，在文檔中是小寫字母。 – tibtof

是啊，我試過，但由於某種原因，它期望小寫... idk爲什麼 – dsthetics

當前您在Unmarshaller上設置Schema以啓用模式驗證，並在您正在解組的驗證XMLReader上創建SAXSource。作爲第一步，我會建議簡化你的代碼，只需做到以下幾點：

 JAXBContext context = JAXBContext.newInstance(c); 
     Unmarshaller um = context.createUnmarshaller(); 
     if (c.equals(RosApplicationDocument.class)) { 
      SchemaFactory schemaFactory = SchemaFactory 
        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 
      Schema schema = schemaFactory.newSchema(new File(pathToXSD)); 
      um.setSchema(schema); 
      InputSource inSrc = new InputSource(new FileReader(pathToFile)); 
      RosApplicationDocument document = (RosApplicationDocument) um 
        .unmarshal(inSrc); 
      RosApplicationDocumentFactory.removeCDATAFromSegments(document); 
      return document; 
     }

失敗，相同的異常 – dsthetics

您可能需要利用上'SchemaFactory'的'setResourceResolver'方法 - HTTP：// docs.oracle.com/javase/6/docs/api/javax/xml/validation/SchemaFactory.html#setResourceResolver(org.w3c.dom.ls.LSResourceResolver）。 –

試圖... – dsthetics

JAXB和EntityResolver
