将 SOAP 字符串消息转换为 SoapMessage 的 NullPointer 异常
NullPointer exception converting SOAP string message to SoapMessage
我正在将 XML 字符串转换为 SOAPMessage。但是，在尝试调用该服务时，我最终得到了一个 NullPointerException。在单步执行代码时，我可以看出它正在尝试为此 uri 命名空间设置一个空前缀："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);

这原来是类路径问题。我的应用程序具有对 Xerces 的传递依赖性的依赖性，但 WebLogic wlfullclient.jar 依赖性已经具有 JAXP。我使用依赖项 "exclusions" 配置删除了传递性 Xerces 依赖项（"xerces" 的 groupId，以及我代码中其他位置的 "xml-apis"），问题就消失了。顺便说一下，在更改代码之前，测试是从命令行进行的，而不是从 Eclipse 进行的。加载 class 的差异可能导致不同的结果。
