我在使用 Apache CXF 时遇到问题。基本上，它是这样的:

<consStatServ xmlns="http://www.portalfiscal.inf.br/nfe" versao="2.00">

进入这个:

<consStatServ xmlns:ns2="http://www.portalfiscal.inf.br/nfe/wsdl/NfeStatusServico2" xmlns="" xmlns="" xmlns:ns5="http://www.portalfiscal.inf.br/nfe" versao="2.00">

导致“重复的默认命名空间声明”异常。

这是我的 Spring 配置:

这是我的测试代码:

private static String XML_TESTE_STATUS =
    "<consStatServ xmlns=\"http://www.portalfiscal.inf.br/nfe\" versao=\"2.00\">" +

    "</consStatServ>";


private NfeStatusServico2Soap12 statusServ;

@Test
public void commitNfeStatusServicoNF() {
    NfeCabecMsg cabec = new NfeCabecMsg();
    cabec.setCUF("31");
    cabec.setVersaoDados("2.00");

    NfeDadosMsg dados = new NfeDadosMsg();
    try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        InputSource is = new InputSource();
        is.setCharacterStream(new StringReader(XML_TESTE_STATUS));
        Document contentDoc = db.parse(is);
        dados.getContent().add(contentDoc.getDocumentElement());
    } catch (ParserConfigurationException e) {
        throw new IllegalArgumentException("Erro ao empacotar o conteúdo, ", e);
    } catch (SAXException e) {
        throw new IllegalArgumentException("Erro ao empacotar o conteúdo, ", e);
    } catch (IOException e) {
        throw new IllegalArgumentException("Erro ao empacotar o conteúdo, ", e);
    }           

    NfeStatusServicoNF2Result ret = this.statusServ.nfeStatusServicoNF2(dados, cabec);
    Object retVal = ret.getContent().iterator().next();
    System.out.println(retVal.getClass());
    System.out.println("***.***.***");

    try {
        Result stringResult = new StringResult();
        TransformerFactory tFactory = TransformerFactory.newInstance();
        Transformer transformer = tFactory.newTransformer();
        transformer.transform(new DOMSource((Node)retVal), stringResult);
        System.out.println("O retorno é: " + stringResult);
    } catch (TransformerException e) {
        throw new IllegalArgumentException("Impossível gerar nova requisição, ", e);
    }
}

@Resource(name="nfeStatusServicoMGWebService")
public void setStatusServ(NfeStatusServico2Soap12 statusServ) {
    this.statusServ = statusServ;
}

对我做错了什么有什么想法吗？

最佳答案

您能否在调用服务之前尝试规范化文档:

Document.normalizeDocument()

我发现 CXF 没有正确序列化消息的问题，我使用了 CXF 转换器功能来修改消息。试一试:

http://cxf.apache.org/docs/transformationfeature.html

关于java - Apache CXF : Duplicate default namespace declaration，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6664699/
