错误：

javax.xml.stream.XMLStreamException: prefix com has been already bound to http://myurl  Rebinding it to http://www.w3.org/2005/08/addressing is an error

我有以下肥皂请求：

<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope" 
            xmlns:env="http://www.w3.org/2003/05/soap-envelope">
   <S:Header xmlns="http://www.w3.org/2005/08/addressing">

      ********
   </S:Body>
</S:Envelope>

我在标题中添加授权令牌，如下所示

<S:Header xmlns="http://www.w3.org/2005/08/addressing">
      *****
      <com:Authorization xmlns:com="http://myurl">
         <com:ApplicationID>******</com:ApplicationID>
         <com:Token>*******</com:Token>
      </com:Authorization>
   </S:Header>

处理程序中的 java 代码在标头中添加授权令牌

SOAPHeader header = envelope.getHeader();
SOAPElement authorization = header.addChildElement("com:Authorization");
                authorization.addNamespaceDeclaration("com", "http://myurl");  
                SOAPElement applicationID =  authorization.addChildElement("com:ApplicationID");
                applicationID.addTextNode("*******");
                SOAPElement token = authorization.addChildElement("com:Token");
                token.addTextNode("*****");

我面临错误：

javax.xml.ws.WebServiceException: javax.xml.stream.XMLStreamException: prefix com has been already bound to http://myurl. Rebinding it to http://www.w3.org/2005/08/addressing is an error

我在发送请求之前得到的授权标头标签如下

<com:Authorization xmlns:com="http://www.w3.org/2005/08/addressing">
   <com:ApplicationID>*****</com:ApplicationID>
   <com:Token />
</com:Authorization>

等待回复

【解决方案1】：

我应用了以下代码，它对我有用

SOAPElement 授权 = header.addChildElement("Authorization","","http://www.reuters.com/ns/2006/05/01/webservices/rkd/Common_1");

这给了我如下授权标头：

<Authorization xmlns="http://www.reuters.com/ns/2006/05/01/webservices/rkd/Common_1">
    <ApplicationID>********</ApplicationID>
   <Token>*******</Token>
</Authorization>
