Soap JAX-WS删除'；ns'；xml标记的前缀

如何在此处删除或重命名“ns2”前缀：

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns2:GetCatalogResponse xmlns:ns2="https://domain.com/">
         <GetCatalogResult>result</GetCatalogResult>
      </ns2:GetCatalogResponse>
   </S:Body>
</S:Envelope>

结果:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns2:GetCatalogResponse xmlns:ns2="https://domain.com/">
         <GetCatalogResult>result</GetCatalogResult>
      </ns2:GetCatalogResponse>
   </S:Body>
</S:Envelope>

结果

By docs@XmlNs应覆盖xml项的默认前缀。但在我的情况下，它不起作用

为什么？

前缀可以通过

SOAPHandler

这样修改

SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();

Iterator iter = body.getChildElements();
while (iter.hasNext()) {
    Object object = iter.next();

    if (object instanceof SOAPElement) {
        SOAPElement element = (SOAPElement) object;
        element.removeNamespaceDeclaration(element.getPrefix());
        element.setPrefix("");
    }
}

SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
SOAPBody body = envelope.getBody();

Iterator iter = body.getChildElements();
while (iter.hasNext()) {
    Object object = iter.next();

    if (object instanceof SOAPElement) {
        SOAPElement element = (SOAPElement) object;
        element.removeNamespaceDeclaration(element.getPrefix());
        element.setPrefix("");
    }
}
