Question

我想在SOAP信封中添加一个标题元素。我的每次尝试都抛出异常：

com.sun.xml.internal.messaging.saaj.soap.impl.HeaderImpl addHeaderElement SEVERE：SAAJ0131：HeaderElements必须是名称空间限定的

我需要在标题中添加一个没有名称空间的简单元素。在这种情况下，我使用了一个处理程序：

public boolean handleMessage(SOAPMessageContext context) {
    try {
        SOAPMessage message = context.getMessage();
        SOAPHeader header = message.getSOAPHeader();
        SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
        if (header == null) {
            header = envelope.addHeader();
        }
        envelope.addNamespaceDeclaration("gat", "http://schemas.datacontract.org/2004/07/Gateway.Servicios");

        QName passwordQname = header.createQName("Password", "gat");
        QName userQname = header.createQName("User", "gat");

        // Here, I’m trying to add a QName with no namespace.
        QName qNameUserCredentials = new QName(XMLConstants.NULL_NS_URI, "MyHeader");
        SOAPHeaderElement userCredentials = header.addHeaderElement(qNameUserCredentials);

        SOAPHeaderElement password = header.addHeaderElement(passwordQname);
        password.addTextNode(this.password);

        SOAPHeaderElement username = header.addHeaderElement(userQname);
        username.addTextNode(this.username);

        userCredentials.addChildElement(password);
        userCredentials.addChildElement(username);
        message.saveChanges();

        StringWriter writer = new StringWriter();
        message.writeTo(new StringOutputStream(writer));
        System.out.println("SOAP message: \n" + writer.toString());
    } catch (SOAPException e) {
        System.out.println("Error occurred while adding credentials to SOAP header." + e.getMessage());
    } catch (IOException e) {
        System.out.println("Error occurred while writing message to output stream." + e.getMessage());
    }
    return true;
}

预期产出：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:gat="http://schemas.datacontract.org/2004/07/Gateway.Servicios" xmlns:tem="http://tempuri.org/">
    <soapenv:Header>
        <MyHeader>   <-- ######## -->
           <gat:Password>da92767c161e4a62b49f23cb8e712d8e</gat:Password>
            <gat:User>3f3a1850e523fd9961cfa2f4d36bd44d</gat:User>
        </MyHeader>  <-- ######## -->
    </soapenv:Header>
    <soapenv:Body>
        <tem:ConsultarMediosPago>
            <tem:codigoPais>MX</tem:codigoPais>
        </tem:ConsultarMediosPago>
    </soapenv:Body>
</soapenv:Envelope>

元素<MyHeader></MyHeader>是我需要添加的内容。

Answer 1

这是不可能的，故障信息很明确。

有关“SOAP标头元素”

的部分，请参阅http://www.w3schools.com/XML/xml_soap.asp

注意： Header元素的所有直接子元素必须是名称空间限定的

Answer 2

这应该有效.. 设置“oasis-200401-wss-wssecurity-secext”名称空间就可以了。

import javax.xml.namespace.QName;
import javax.xml.soap.*;
QName QUsername = new QName("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", "Username");
SOAPHeaderElement usernameElement = soapHeader.addHeaderElement(QUsername);
usernameElement.addTextNode("user-id-here");

This will give below output
<Username>user-id-here</Username>

添加没有命名空间的SOAP头元素
