当 Soap Fault 调用 Java Web Service 时,我有这种响应

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Server</faultcode>
            <faultstring>Fault occurred while processing.</faultstring>
            <detail>
                <ns1:WaybillRegistrationFault xmlns:ns1="http://pod.waybillmanagement.ws.industrysystem.com.ar/">
                    <errors xmlns:ns2="http://pod.waybillmanagement.ws.industrysystem.com.ar/">
                        <code>80000</code>
                        <description>El número de CTG 20140904 ya existe</description>
                    </errors>
                    <errors xmlns:ns2="http://pod.waybillmanagement.ws.industrysystem.com.ar/">
                        <code>1000</code>
                        <description>La carta de porte ya se encuentra registrada.</description>
                    </errors>
                </ns1:WaybillRegistrationFault>
            </detail>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

我用它的 handleFault 方法做了一个 Soap Handler:public boolean handleFault(SOAPMessageContext context){

try {
        System.err.println("Handler handleFault");

        if (context.getMessage().getSOAPBody().hasFault()) {
            SOAPFault fa = context.getMessage().getSOAPBody().getFault();
            System.err.println(fa.getFaultString());
            System.err.println("FaultCode: " + fa.getFaultCode() + " - Detail: " + fa.getDetail());
        }
        return true;
    } catch (SOAPException ex) {
        System.err.println("SoapEx " + ex.getMessage());
        return true;
    }
}

但在我的输出中我只有:

Handler handleFault
Fault occurred while processing.
FaultCode: soap:Server - Detail: [detail: null]

如何处理错误节点?

更新:

fa.getDetail().getFirstChild().getTextContent()我得到 xml 中的文本。我如何将其作为对象。我认为这是一个 WaybillRegistrationFault。

    如果要将故障内容打印为 xml 字符串,则必须将 fa.getDetail()返回的 dom 实例转换为 String,fa.getDetail().toString() return [1]“而不是 xml 的内容。

    尝试以下方法;

    String detailStr=dom2string(fa.getDetail())
    System.err.println("FaultCode: " + fa.getFaultCode() + " - Detail: " + detailStr); 
    
    public static final String dom2string(Node node) {
        try {
            if (node == null) {
                return null;
            }
    
            Transformer tf = transformerThreadLocal.get();
            // Create writer
            StringWriter sw = new StringWriter(buffer, Integer.MAX_VALUE);
            StreamResult result = new StreamResult(sw);
    
            // transform
            tf.transform(new DOMSource(node), result);
    
            return sw.getBuffer();
        } catch (Exception e) {
            throw new RuntimeException("Could not convert Node to string", e);
        }
    }

    这是我总是处理肥皂故障错误的方式:

    `StringWriter sw = new StringWriter();
    TransformerFactory.newInstance().newTransformer().transform(
    new DOMSource(soapFaultException.getFault()), new StreamResult(sw));
    String xml = sw.toString();`
