CXF 获取SoapHeader问题

Map<String, Object> headers = context.getMessageContext();
List<Header> headerList = (List<Header>)headers.get(Header.HEADER_LIST);
for (Header header : headerList) {
 Node root = (Node) header.getObject();
System.out.println("soap header name：" + root.getNodeName() + " text：" + root.getTextContent());
            if("RequestSOAPHeader".equals(root.getNodeName())){
NodeList list = root.getChildNodes();
int size = list.getLength();
for(int i=0;i<size;i++){
Node node = list.item(i);
System.out.println("soap header name：" + node.getNodeName() + " text：" + node.getTextContent());
}
}
}
