java - 将 SOAP 字符串消息转换为 SoapMessage 时出现 NullPointer 异常

Question

我正在将 XML 字符串转换为 SOAPMessage。但是，在尝试调用该服务时，我最终得到了 NullPointerException。单步执行代码时，我可以看出它正在尝试为此 uri 命名空间设置空前缀:“urn:oasis:names:tc:ebxml-regrep:xsd:query:3.0”。

代码:

    //PORT_NAME={urn:ihe:iti:xds-b:2007}RespondingGateway_Port_Soap12
    //SERVICE_NAME={urn:ihe:iti:xds-b:2007}RespondingGateway_Service
        Service service = Service.create(SERVICE_NAME);
        service.addPort(PORT_NAME, SOAPBinding.SOAP12HTTP_BINDING, endpointUrl);
        Dispatch<SOAPMessage> dispatch = service.createDispatch(PORT_NAME,
                SOAPMessage.class, Service.Mode.MESSAGE);
        squashWSA(dispatch);
        addHttpHeaders(dispatch, messageId);
        //set the request timeout value
        dispatch.getRequestContext().put(JAXWSProperties.CONNECT_TIMEOUT, haimsConnectTimeout);
        dispatch.getRequestContext().put(JAXWSProperties.REQUEST_TIMEOUT, haimsReceiveTimeout);

            byte[] msgBytes = domToBytes(rawSoapRqst);
    MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
            SOAPMessage request = mf.createMessage(new MimeHeaders(), new ByteArrayInputStream(msgBytes));
            SOAPMessage response = dispatch.invoke(request);

Answer 1

事实证明这是一个类路径问题。我的应用程序具有对 Xerces 的传递依赖项，但 WebLogic wlfullclient.jar 依赖项已经具有 JAXP。我使用依赖项“exclusions”配置来删除传递性 Xerces 依赖项(“xerces”的 groupId 和代码中其他位置的“xml-apis”)，问题就消失了。顺便说一句，在代码更改之前，测试是从命令行进行的，而不是从 Eclipse 进行。加载类的差异可能会导致不同的结果。
