Web services jaxb向元素添加名称空间

根据我的任务，我必须调用SOAP服务。因此，我使用xjc从wsdl生成了java类。但我在调用SOAP服务时遇到了一个问题。我的应用程序生成此请求：

    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"/><soap:Body>
<typ:SendMessage xmlns:ns4="http://test.user.kz/UserInfo" xmlns:q1="http://test.user.kz/CustomerInfo" xmlns:typ="http://test.user.kz/MyChannel/v1/Types">
    <request>
        <requestInfo>
            <messageId>26e96b11-8f82-421e-829a</messageId>
        </requestInfo>
        <requestData>
            <data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="q1:PaymentPackageRequestType">
                <q1:methodName>testMethod</q1:methodName>
            </data>
        </requestData>
    </request>
</typ:SendMessage></soap:Body></soap:Envelope>

如何在数据标记中指定名称空间？ 这是我当前的包裹信息：

@javax.xml.bind.annotation.XmlSchema(
        xmlns = {
            @javax.xml.bind.annotation.XmlNs(prefix = "typ",
                    namespaceURI = "http://test.user.kz/MyChannel/v1/Types"),
            @javax.xml.bind.annotation.XmlNs(prefix = "q1",
                    namespaceURI = "http://test.user.kz/CustomerInfo")
        },
   elementFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED,
   attributeFormDefault = javax.xml.bind.annotation.XmlNsForm.UNSET
)
package kz.uni.gen;

因此，我无法添加名称空间xmlns:q1=”http://test.user.kz/CustomerInfo“到SOAP请求中的数据标记。如何添加此命名空间声明或从SendMessage标记移动命名空间声明？

因此使用JAXB是不可能的。因此，我在必需元素中手动添加了名称空间。这是完整的代码片段：

Document document = null;
        try {
            document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
            Marshaller marshaller = JAXBContext.newInstance(SendMessage.class).createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            marshaller.setProperty("com.sun.xml.bind.characterEscapeHandler", new CharacterEscapeHandler() {
                @Override
                public void escape(char[] buf, int start, int len, boolean b, Writer out) throws IOException {
                    out.write(buf, start, len);
                }
            });
            QName name = new QName(NAMESPACE_URI, SendMessage.class.getSimpleName());
            JAXBElement<SendMessage> root = new JAXBElement<SendMessage>(name, SendMessage.class, from);
            StringWriter writer1 = new StringWriter();
            marshaller.marshal(root, writer1);
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            dbf.setNamespaceAware(true);
            Element node = dbf
                    .newDocumentBuilder()
                    .parse(new ByteArrayInputStream(writer1.toString().getBytes(StandardCharsets.ISO_8859_1)))
                    .getDocumentElement();
            Attr attr1 = document.createAttribute("xmlns:q1");
            attr1.setValue("http://test.user.kz/CustomerInfo");
            node.getElementsByTagName("data").item(0).getAttributes().setNamedItem(node.getOwnerDocument().importNode(attr1, true));
            return node;
        } catch (Exception e) {
            throw new Exception("Unable to transform POJO to XML SOAP message ", e);

        }

单据单据=null；
试一试{
document=DocumentBuilderFactory.newInstance（）.newDocumentBuilder（）.newDocument（）；
Marshaller Marshaller=JAXBContext.newInstance（SendMessage.class）.createMarshaller（）；
setProperty（marshaller.JAXB_编码，“UTF-8”）；
setProperty（marshaller.JAXB_格式的_输出，Boolean.TRUE）；
setProperty（“com.sun.xml.bind.characterEscapeHandler”，新的characterEscapeHandler（）{
@凌驾
公共void转义（char[]buf，int start，int len，boolean b，Writer out）抛出IOException{
输出。写入（buf、start、len）；
}
});
QName name=新的QName（名称空间_URI，SendMessage.class.getSimpleName（））；
JAXBElement root=newjaxbelement（名称，sendmages.class，from）；
StringWriter writer1=新的StringWriter（）；
marshaller.marshall（根，writer1）；
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance（）；
dbf.setNamespaceAware（true）；
元素节点=dbf
.newDocumentBuilder（）
.parse（新的ByteArrayInputStream（writer1.toString（）.getBytes（StandardCharsets.ISO_8859_1）））
.getDocumentElement（）；
Attr attr1=document.createAttribute（“xmlns:q1”）；
属性1.设置值（“http://test.user.kz/CustomerInfo");
node.getElementsByTagName（“数据”）.item（0.getAttributes（）.setNamedItem（node.getOwnerDocument（）.importNode（attr1，true））；
返回节点；
}捕获（例外e）{
抛出新异常（“无法将POJO转换为XML SOAP消息”，e）；
}
