Java 如何从SOAP消息中删除空标头？

我使用SpringWS来消费Webservice，如果SOAP信封有空的头元素，它将与之相比较。我发现默认的SOAPMessage实现增加了一个

我怎样才能删除它

提前感谢

：

下一行是一个空的SOAP头。您可以通过调用 getSOAPHeader调用后的header.detachNode

下面是普通SAAJ中的解决方案：

        MessageFactory messageFactory = MessageFactory.newInstance("SOAP 1.2 Protocol");
        SOAPMessage message = messageFactory.createMessage();
        message.getSOAPHeader().detachNode(); // suppress empty header

下面是使用spring ws的解决方案，它基于：

public void marshalWithSoapActionHeader(MyObject o) {

    webServiceTemplate.marshalSendAndReceive(o, new WebServiceMessageCallback() {

        public void doWithMessage(WebServiceMessage message) {
            SaajSoapMessage saajSoapMessage = (SaajSoapMessage) message;
            SOAPMessage soapMessage = saajSoapMessage.getSaajMessage();
            SOAPPart soapPart = soapMessage.getSOAPPart();
            SOAPEnvelope envelope = soapPart.getEnvelope();
            SOAPHeader header = soapMessage.getSOAPHeader(); 
            header.detachNode();
        }
    });
}
