如何将不带前缀的 childElements 添加到 Soap 标头？答案

【问题标题】：How to add childElements without prefix to Soap header?如何将不带前缀的 childElements 添加到 Soap 标头？

【问题描述】：

我需要向 Soap 请求添加标头元素，但标头内的子元素没有定义任何前缀。当我尝试在不指定前缀的情况下添加元素时，会引发异常。

private SOAPHeader addSecuritySOAPHeader(SOAPMessageContext context) {
SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
envelope.addNamespaceDeclaration("S", "http://schemas.xmlsoap.org/soap/envelope/");
envelope.addNamespaceDeclaration("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");

SOAPEnvelope header = envelope.getHeader();
// ACTION NODE
SOAPElement action = header.addChildElement("Action");
return header;
}

最后一行产生下一个异常 “com.sun.xml.messaging.saaj.SOAPExceptionImpl：HeaderElements 必须是命名空间限定的”

我需要创建的Heaser：

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <S:Header>
    <Action xmlns="http://schemas.xmlsoap.org/ws/2004/08/addressing">http://cgbridge.rategain.com/2011A/ReservationService/HotelResNotif</Action>
  </S:Header>
  ..............
</S:Envelope>

如果我包含任何前缀，例如 S，请求失败，服务器响应“错误请求”

如何添加“干净”的 Action 节点？

我是否在操作中添加了前缀： SOAPElement action = header.addChildElement("Action","S"); 带有“错误请求”消息的服务响应。

<S:Action xmlns="http://schemas.xmlsoap.org/ws/2004/08/addressing">http://cgbridge.rategain.com/2011A/ReservationService/HotelResNotif</S:Action>

有什么帮助吗？

【解决方案1】：

这应该有效：

@Test
public void someTest() throws Exception {
    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage soapMessage = messageFactory.createMessage();

    SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();
    var header = soapEnvelope.getHeader();
    var actionElement = header.addChildElement("Action", "prefix", "http://schemas.xmlsoap.org/ws/2004/08/addressing");
    actionElement.addTextNode("http://cgbridge.rategain.com/2011A/ReservationService/HotelResNotif");

    ByteArrayOutputStream out = new ByteArrayOutputStream();
    soapMessage.writeTo(out);
    System.out.println(new String(out.toByteArray()));
}

打印：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header><prefix:Action xmlns:prefix="http://schemas.xmlsoap.org/ws/2004/08/addressing">http://cgbridge.rategain.com/2011A/ReservationService/HotelResNotif</prefix:Action></SOAP-ENV:Header><SOAP-ENV:Body/></SOAP-ENV:Envelope>
