JAXB如何正確生成XML？

我試圖消費一個在soap請求中使用兩個名稱空間的webservice，但它不接受任何前綴。我使用cxf來生成客戶端和數據綁定。當使用JAXB作爲默認的數據綁定，這是發送到Web服務的服務器的消息：JAXB如何正確生成XML？

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> 
    <soap:Header> 
     <nfeCabecMsg xmlns:ns2="http://www.portalfiscal.inf.br/nfe" 
        xmlns="http://www.portalfiscal.inf.br/nfe/wsdl/NfeStatusServico2"> 
      <cUF>31</cUF> 
      <versaoDados>2.00</versaoDados> 
     </nfeCabecMsg> 
    </soap:Header> 
    <soap:Body> 
     <nfeDadosMsg xmlns="http://www.portalfiscal.inf.br/nfe/wsdl/NfeStatusServico2" 
        xmlns:ns2="http://www.portalfiscal.inf.br/nfe"> 
      <ns2:consStatServ versao="2.00"> 
       <ns2:tpAmb>2</ns2:tpAmb> 
       <ns2:cUF>31</ns2:cUF> 
       <ns2:xServ>STATUS</ns2:xServ> 
      </ns2:consStatServ> 
     </nfeDadosMsg> 
    </soap:Body> 
</soap:Envelope>

但是這不是服務器期望的格式。使用XMLBean的默認數據綁定我可以正確生成消息（如服務器期望）：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> 
    <soap:Header> 
     <nfeCabecMsg xmlns="http://www.portalfiscal.inf.br/nfe/wsdl/NfeStatusServico2"> 
      <cUF>31</cUF> 
      <versaoDados>2.00</versaoDados> 
     </nfeCabecMsg> 
    </soap:Header> 
    <soap:Body> 
     <nfeDadosMsg xmlns="http://www.portalfiscal.inf.br/nfe/wsdl/NfeStatusServico2"> 
      <consStatServ xmlns="http://www.portalfiscal.inf.br/nfe" versao="2.00"> 
       <tpAmb>2</tpAmb> 
       <cUF>31</cUF> 
       <xServ>STATUS</xServ> 
      </consStatServ> 
     </nfeDadosMsg> 
    </soap:Body> 
</soap:Envelope>

不過，我真的affraid有關使用XmlBeans的，因爲我的軟件的另一個重要部分是使用JAXB開發，我可能需要將其更改爲XmlBeans。在我看到XmlBeans的最後一個版本是在2012年之後，我不確定將來會支持XmlBeans。有沒有一種方法可以使用JAXB正確生成消息？

這些是用於創建consStatServ標籤最相關的模式：

你可以發佈你的JAXB源代碼（xsd或Annotated Java Classes）嗎？ – superbob

我終於解決了這個問題。由於這是第三方Web服務，我唯一的選擇是編輯由JAXB生成的類。我做的第一件事是從package-info.java文件中刪除命名空間屬性。然後，我也做了同樣的的ObjectFactory類，在這裏我只是從改變的QName構造：

的QName（字符串的namespaceURI，字符串的localpart）

到

的QName （String localPart）

不幸的是，這些修改不刪除前綴，所以我實現我自己的CXF interceptor：

public class NamespacePrefixInterceptor extends AbstractPhaseInterceptor<Message> { 
    public NamespacePrefixInterceptor() { 
     super(Phase.PRE_STREAM); 
     addBefore(SoapPreProtocolOutInterceptor.class.getName()); 
    } 

    @Override 
    public void handleMessage(Message message) throws Fault { 
     if (isOutbound(message)) { 
      OutputStream outputStream = message.getContent(OutputStream.class); 
      CachedOutputStream cachedOutputStream = new CachedOutputStream(); 
      message.setContent(OutputStream.class, cachedOutputStream); 
      message.getInterceptorChain().doIntercept(message); 
      try { 
       cachedOutputStream.flush(); 
       CachedOutputStream messageStream = (CachedOutputStream) message.getContent(OutputStream.class); 
       String currentEnvelopeMessage = IOUtils.toString(messageStream.getInputStream(), "UTF-8"); 
       currentEnvelopeMessage = currentEnvelopeMessage.replaceAll("ns2:", ""); 
       currentEnvelopeMessage = currentEnvelopeMessage.replaceAll(":ns2", ""); 
       messageStream.flush(); 
       messageStream.close(); 
       InputStream replaceInStream = new ByteArrayInputStream(currentEnvelopeMessage.getBytes(StandardCharsets.UTF_8)); 
       IOUtils.copy(replaceInStream, outputStream); 
       replaceInStream.close(); 
       outputStream.flush(); 
       message.setContent(OutputStream.class, outputStream); 
       outputStream.close(); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    } 

    private boolean isOutbound(Message message){ 
     return message == message.getExchange().getOutMessage() 
      || message == message.getExchange().getOutFaultMessage(); 
    } 
}

有了這個攔截我終於可以刪除的命名空間。最後一個問題是名稱空間xmlns =「http://www.portalfiscal.inf.br/nfe」應該出現在consStatServ元素中。由於所有不必要的命名空間是在JAXB生成的類修改後取出，我做了變通方法簡單地創建ConsStatServ類xmln屬性：

public class ConsStatServ { 
    . 
    . 
    . 
    @XmlAttribute(name = "xmlns", required = true) 
    @XmlJavaTypeAdapter(CollapsedStringAdapter.class) 
    protected String xmlns = "http://www.portalfiscal.inf.br/nfe"; 
    public String getXmlns() { 
     return xmlns; 
    } 
}

我知道這個解決方案是一個龐大的雜牌，但我找不到另外一個選擇。

你可能想用http://docs.oracle.com/javaee/5/api/javax/xml/bind/annotation/XmlElement.html對你的基因組元素進行註釋編輯類。它具有您感興趣的命名空間參數。我們之前有過類似的問題，並且能夠使其與這些手動更新一起工作。

Web服務不接受soap消息中的任何名稱空間前綴。如果消息至少有一個名稱空間前綴，則返回被拒絕。 – brevleq

@brevleq，這似乎是你打電話的服務中一個非常重要的缺陷。他們提供了一個理由，爲什麼格式良好的xml對提供的模式有效將被拒絕？一旦涉及多個模式名稱空間，防止使用前綴將可能導致適用的名稱空間被重複聲明，而不是在更高級別上進行1次聲明。把它看作一直使用完全合格的java類名稱，而不是在類的頂部有一個import語句（這不是一個完美的類比，但很接近）。 –

@brevieq嘗試在XmlElement註釋中專門爲需要名稱空間的XML中的每個元素設置「namespace」參數：nfeDadosMsg和consStatServ。嘗試在XmlType註釋上設置namespace =「」。我知道這不是處理這個問題的最好方法，它是使它在我們的案例中工作的唯一方法。 – Artem
