使用JAXB的Unmarshalle xml文件

以前可能會問這個問題，但我已經嘗試過幾乎所有以前發佈的解決方案。我很新的這一點，其中的問題是我無法弄清楚：使用JAXB的Unmarshalle xml文件

以下是我的XML文件：

<?xml version="1.0" encoding="UTF-8"?> 
<TaxAddressFileDeliveryConfirmation> 
    <ReturnInfo> 
    <ErrorCode>FAILURE</ErrorCode> 
    <ErrorMessage>abc. 
    </ErrorMessage> 
</ReturnInfo> 
<TaxAddressFileDeliveryNotification> 
    <FileNameInput>abc 
    </FileNameInput> 
    <FileNameOutput>abc 
    </FileNameOutput> 
    <MessageCount>20000</MessageCount> 
    <ReplyMessageSubject>abc 
    </ReplyMessageSubject> 
    <ProcessingOption NAME="TAR">Y</ProcessingOption> 
</TaxAddressFileDeliveryNotification> 
</TaxAddressFileDeliveryConfirmation>

以下是Java代碼：

public class CheckSampleXMLUnmarshall { 
    public static void main(String[] args) { 
     try { 

      File file = new File(
        "Sample.xml"); 
      JAXBContext jaxbContext = JAXBContext 
        .newInstance(TaxAddressFileDeliveryConfirmation.class); 

      Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller(); 
      Object resposeObj = JAXBIntrospector.getValue(jaxbUnmarshaller 
        .unmarshal(file)); 
      System.out.println(resposeObj); 

     } catch (JAXBException e) { 
      e.printStackTrace(); 
     } 
    } 
}

我得到以下錯誤：

javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"TaxAddressFileDeliveryConfirmation"). Expected elements are <{http://www.example.org/TaxAddressFileDeliveryNotification}TaxAddressDeliveryNotification>,<{http://www.example.org/TaxAddressFileDeliveryConfirmation}TaxAddressFileDeliveryConfirmation>

我到底需要檢查什麼？

看起來你的xml不符合它的模式。特別是，它看起來像命名空間已關閉。你有架構嗎？ – bradimus

您的XML不符合您的模式（XSD），或者至少它不符合從XSD（或您以某種其他方式創建的與XSD匹配的方式創建的）生成的JAXB類。

的XSD在http://www.example.org/TaxAddressFileDeliveryConfirmation命名空間期待的元素：{http://www.example.org/TaxAddressFileDeliveryConfirmation}TaxAddressFileDeliveryConfirmation但XML文檔顯示了一個不合格的（沒有命名空間）TaxAddressFileDeliveryConfirmation元素

如果你手工創建這個XML文件，你可能需要限定像這樣的頂級元素：

<?xml version="1.0" encoding="UTF-8"?> 
<tns:TaxAddressFileDeliveryConfirmation xmlns:tns="http://www.example.org/TaxAddressFileDeliveryConfirmation"> 
...

但是完整的答案取決於您的XSD。

這是一個非常簡單的問題，所以你應該在StackOverflow上找到很多類似的問題/答案。
