java - SoapFaultException - 提取代码和文本

Question

我想从下面列出的肥皂故障中单独提取代码和文本。我正在使用的代码(在 xml 下面列出)将代码和文本一起打印。

<env:Fault xmlns:env = "http://schemas.xmlsoap.org/soap/envelope/" xmlns:fault = "http://schemas.xmlsoap.org/soap/envelope/">
    <faultcode>fault:Client</faultcode>
    <faultstring>An error occurred. Please check the detail section.</faultstring>
    <detail>
        <e:serviceFault xmlns:e = "http://xml.comcast.com/types">
            <e:messages>
                <e:message>
                    <e:code>ERRORCODE-82828</e:code>
                    <e:text>Error Message.</e:text>
                </e:message>
            </e:messages>
        </e:serviceFault>
    </detail>
</env:Fault>

代码

public void printSoapFaultClientException(SoapFaultClientException e) {
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = null;
    transformer = transformerFactory.newTransformer();

    DOMResult result = new DOMResult();

        transformer.transform(e.getSoapFault().getSource(), result);
        NodeList nl = ((Document)result.getNode()).getElementsByTagName("detail");

    System.out.println(" text content " + ((Element)nl.item(0)).getTextContent());

}

这是一个执行此操作的示例，因为它是一个错误 XML，所以我刚刚使用解析器来解析 XML 并从中提取字段。如果您需要的话，SOAPFaultClientException API 还可以帮助您直接提取故障原因 ( http://docs.spring.io/spring-ws/site/apidocs/org/springframework/ws/soap/client/SoapFaultClientException.html )

File fXmlFile = new File("C:\\DevelopmentTools\\3.CODE\\SOAP.txt");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();

XPath xpath = XPathFactory.newInstance().newXPath();
String responseStatus = xpath.evaluate("//*[local-name()='code']/text()", doc);
String responseText = xpath.evaluate("//*[local-name()='text']/text()", doc);
System.out.println("---> " + responseStatus);
System.out.println("---> " + responseText);
