如何使用Apache Axis2和WSDL2Java向SOAP响应添加命名空间引用 [英] How do I add a namespace reference to a SOAP response with Apache Axis2 and WSDL2Java

问题描述

我正在查看我正在开发的Web服务的SOAP输出，我发现了一些好奇的东西：

I'm looking at the SOAP output from a web service I'm developing, and I noticed something curious:

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
   <soapenv:Body>
      <ns1:CreateEntityTypesResponse xmlns:ns1="http://somedomain.com/wsinterface">
         <newKeys>
            <value>1234</value>
         </newKeys>
         <newKeys>
            <value>2345</value>
         </newKeys>
         <newKeys>
            <value>3456</value>
         </newKeys>
         <newKeys xsi:nil="1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
         <newKeys xsi:nil="1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
         <errors>Error1</errors>
         <errors>Error2</errors>
      </ns1:CreateEntityTypesResponse>
   </soapenv:Body>
</soapenv:Envelope>

我有两个newKeys元素是nil，两个元素都插入了xsi的命名空间引用。我想在soapenv：Envelope元素中包含该命名空间，以便命名空间引用只发送一次。

I have two newKeys elements that are nil, and both elements insert a namespace reference for xsi. I'd like to include that namespace in the soapenv:Envelope element so that the namespace reference is only sent once.

我使用WSDL2Java生成服务框架，所以我无法直接访问Axis2 API。

I am using WSDL2Java to generate the service skeleton, so I don't directly have access to the Axis2 API.

推荐答案

使用WSDL2Java

如果您已经使用过Axis2 WSDL2Java工具，那么您可能会遇到它为您生成的内容。但是，您可以尝试更改此部分中的框架：

Using WSDL2Java

If you have used the Axis2 WSDL2Java tool you're kind of stuck with what it generates for you. However you can try to change the skeleton in this section:

   // create SOAP envelope with that payload
   org.apache.axiom.soap.SOAPEnvelope env = null;
   env = toEnvelope(
       getFactory(_operationClient.getOptions().getSoapVersionURI()),
       methodName,
       optimizeContent(new javax.xml.namespace.QName
       ("http://tempuri.org/","methodName")));

//adding SOAP soap_headers
_serviceClient.addHeadersToEnvelope(env);

要将名称空间添加到信封中，请在其中的某处添加以下行：

To add the namespace to the envelope add these lines somewhere in there:

OMNamespace xsi = getFactory(_operationClient.getOptions().getSoapVersionURI()).
    createOMNamespace("http://www.w3.org/2001/XMLSchema-instance", "xsi");

env.declareNamespace(xsi);

手工编码

如果你是手工编码你可能会做这样的服务：

Hand-coded

If you are "hand-coding" the service you might do something like this:

SOAPFactory fac = OMAbstractFactory.getSOAP11Factory();   
SOAPEnvelope envelope = fac.getDefaultEnvelope();
OMNamespace xsi = fac.createOMNamespace("http://www.w3.org/2001/XMLSchema-instance", "xsi");

envelope.declareNamespace(xsi);
OMNamespace methodNs = fac.createOMNamespace("http://somedomain.com/wsinterface", "ns1");

OMElement method = fac.createOMElement("CreateEntityTypesResponse", methodNs);

//add the newkeys and errors as OMElements here...

在aar中公开服务

如果要在aar中创建服务，则可能会影响使用目标命名空间或模式命名空间属性生成的SOAP消息（请参阅< a href =http://wso2.org/library/2060 =noreferrer>这篇文章）。
