在有效的SOAP SAAJ信封中使用默認命名空間

[英]Use default namespace in valid SOAP SAAJ envelope

這兩條肥皂信息有效嗎? 不同的部分是命名空間屬性xmlns =“http://www.sigvalue.com/acc”。 第一個soap是一個樣本,第二個是由java代碼生成的,用於生成相同的soap消息。

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
  <GetNGPList xmlns="http://www.sigvalue.com/acc">
  <UserData>
    <senderId>string</senderId>
    <channelId>string</channelId>
    <timeStamp>dateTime</timeStamp>
  </UserData>
  <zipCode>string</zipCode>
</GetNGPList>
 </soap:Body>
</soap:Envelope>

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetNGPList>
  <UserData xmlns="http://www.sigvalue.com/acc">
    <senderId>string</senderId>
    <channelId>string</channelId>
    <timeStamp>dateTime</timeStamp>
  </UserData xmlns="http://www.sigvalue.com/acc">
  <zipCode>string</zipCode>
</GetNGPList>
</soap:Body>
</soap:Envelope>

如果第二個肥皂無效,我怎么能和第一個肥皂一樣? GetNGPList.addNamespaceDeclaration(“xmlns”,“ http://www.sigvalue.com/acc ”); 這條線不能按預期工作。 這是JAVA代碼:

    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage soapMessage = messageFactory.createMessage();

    SOAPPart soapPart = soapMessage.getSOAPPart();


    // SOAP Envelope
    SOAPEnvelope envelope = soapPart.getEnvelope();
    envelope.addNamespaceDeclaration("xsi", gXSIServerURI);
    envelope.addNamespaceDeclaration("xsd", gXSDServerURI);

        // SOAP Body
    SOAPBody soapBody = envelope.getBody();
    SOAPElement GetNGPList =  soapBody.addChildElement("GetNGPList");
    GetNGPList.addNamespaceDeclaration("xmlns","http://www.sigvalue.com/acc");

    SOAPElement UserData = GetNGPList.addChildElement("UserData");
    SOAPElement senderId = UserData.addChildElement("senderId");
    SOAPElement channelId = UserData.addChildElement("channelId");
    SOAPElement timeStamp = UserData.addChildElement("timeStamp");
    senderId.addTextNode("string");
    channelId.addTextNode("string");
    timeStamp.addTextNode("dateTime");

    SOAPElement zipCode = GetNGPList.addChildElement("zipCode");
    zipCode.addTextNode("string"); 


    MimeHeaders headers = soapMessage.getMimeHeaders();
    headers.addHeader("SOAPAction",  "sample");

    soapMessage.saveChanges();

    /* Print the request message */
    //System.out.print("Request SOAP Message = ");
    soapMessage.writeTo(System.out);

要將名稱空間設置為默認名稱空間 ,只需使用空字符串( "" )作為前綴名稱

SOAPElement GetNGPList =
       soapBody.addChildElement("GetNGPList", "", "http://www.sigvalue.com/acc");
                                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

上面的代碼將xmlns="http://www.sigvalue.com/acc"應用於GetNGPList

你的代碼改編:

// SOAP Body
SOAPBody soapBody = envelope.getBody();
SOAPElement GetNGPList =
       soapBody.addChildElement("GetNGPList", "", "http://www.sigvalue.com/acc");

SOAPElement UserData = GetNGPList.addChildElement("UserData");
...

像往常一樣,當您在addChildElement()省略命名空間前綴聲明時,子節點從其父節點繼承其命名空間。

上面的代碼將生成您需要的內容:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
                   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <SOAP-ENV:Header />
    <SOAP-ENV:Body>
        <GetNGPList xmlns="http://www.sigvalue.com/acc">
            <UserData>
                <senderId>string</senderId>
...

你可以刪除這一行:

GetNGPList.addNamespaceDeclaration("xmlns","http://www.sigvalue.com/acc");

並添加此行

envelope.addNamespaceDeclaration("","http://www.sigvalue.com/acc");

幾點說明:

  • 我建議使用框架來處理Web服務,Apache CXF可以為您做很多棘手的工作: http//cxf.apache.org/

  • 確保遵循正常的命名標准,這使得更容易閱讀代碼。 變量GetNGPList應該是getNGPList
