我對JAXB和驗證很陌生,並花了幾個小時試圖找出這個問題無濟於事。我創建了一個簡單的JAXB unmarshaller示例來解析XML文件。我也創建了一個合適的XSD文件,但驗證器一直抱怨說它無法找到元素的聲明。JAXB unmarshal驗證拋出cvc-elt.1:找不到元素錯誤的聲明
我認爲這可能與命名空間問題有關,但我試過了所有我能想到的,仍然無法解決錯誤的方法。據我所知,我的XSD和XML是正確的,所以它可能與我實例化unmarshaller的方式有關,但我似乎無法在任何地方找到問題。
錯誤/例外,我不斷收到是:

下面是導致該錯誤的源文件。
Java代碼:
// We need a Document
InputStream is = UnmarshalTest.class.getClassLoader().getResourceAsStream("calculateBorrowingDataResponse.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Node node = db.parse(is);
// Creating an unmarshaller
Unmarshaller u = JAXBContext.newInstance(CalculateBorrowingDataResponseType.class).createUnmarshaller();
// Setting the Validation
Schema schema;
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
schema = schemaFactory.newSchema(new File("src/main/webapp/WEB-INF/wsdl/CalculateBorrowingDataResponse.xsd"));
u.setSchema(schema);
u.unmarshal(node, CalculateBorrowingDataResponseType.class);

我既沒有在XSD的最後一個元素定義嘗試(即:xsd:element name =「calculateBorrowingDataResponse」...)但都不起作用。
我正在用盡不同想法的想法嘗試。任何建議或建議將不勝感激!
您是用手還是用XJC創建了JAXB類?此外,您正在引用的* SimpleType.xsd *是什麼?沒有這些信息,很難進行快速測試。 – 2012-01-08 07:09:21
是的 - 我用XJC生成類。我實際上嘗試過使用XJC和eclipse插件(使用maven central的jaxb-2.1.9-osgi作爲我的pom中的jaxb實現)。兩種方式我都有同樣的錯誤。 我編輯了上面的問題,並用包含SimpleType.xsd中相關類型的新版本替換原始XSD架構,以便只有一個架構文件並且不再依賴SimpleType.xsd。但爲了清楚起見,我留下了原始的名稱空間標識符。 – 2012-01-09 17:56:00
我也編輯了我的帖子,爲我的calculateBorrowingDataResponse.xml示例數據添加了定義。 – 2012-01-09 18:03:07
