本文主要讲述了在使用WebService+XML调用他人接口时遇到的问题。最初，使用此方式能成功调用Java发布的服务，但当尝试调用用M语言编写的服务时出现不兼容问题。通过调整为直接拼装SOAP消息的方式，成功解决了调用不通的问题，并且还涉及了解析SOAP消息及处理乱码的细节。

1. 之前用webservice+xml调用别人接口，用这种方式调用自己用java发布的服务可以调通

服务调用：

try {
            call = (Call) service.createCall();
            call.setSOAPActionURI("http://。。。.HIPMessageServer");
            call.setTargetEndpointAddress(new java.net.URL(endpoint));// 远程调用路径
            call.setOperationName(new QName("http://。。。", "HIPMessageServer"));// 调用的方法名

            // 设置参数名:
            call.addParameter("arg0", // 参数名
                    XMLType.XSD_STRING,// 参数类型:String
                   javax.xml.rpc.ParameterMode.IN);// 参数模式：'IN' or 'OUT'
           call.addParameter("arg1",XMLType.XSD_STRING,// 参数类型:String
                   javax.xml.rpc.ParameterMode.IN);

           // 设置返回值类型：
            //call.setReturnType(XMLType.XSD_STRING);// 返回值类型：String

           result = (String) call.invoke(new Object[]{ss});// 远程调用

java服务发布：

接口

@WebService
public interface ManagerService {

    String SendManagerDataInfo(String messageId, String xmlStr);

    String SendDoctorDataInfo(String messageId, String xmlStr);

    String PatientRegistry(String messageId, String xmlStr);

}

实现类：

@Service("PublishService")
@WebService(endpointInterface = "com.service.PublishService")
public class PublishServiceImpl implements PublishService {
    @Autowired
    ManagerService managerService;
    @Override
    public String HIPMessageServer(String serviceNum, String xmlStr) {
        String result="错误";
        if(serviceNum.equals("MS003")){
            result = managerService.SendManagerDataInfo(serviceNum,xmlStr);
        }
        else if(serviceNum.equals("MS004")){
            result = managerService.SendDoctorDataInfo(serviceNum, xmlStr);
        }
        else if(serviceNum.equals("T0004")){
            result = managerService.PatientRegistry(serviceNum, xmlStr);
        }
        return result;
    }
}

后来发现别人使用m语言写的，一般方法掉不通，换了一种调用方式直接拼装soap消息发过去就通了

   String endpoint = "wsdl路径";
        SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection connection = soapConnFactory.createConnection();
        MessageFactory factory = MessageFactory.newInstance();
        SOAPMessage message = factory.createMessage();
        SOAPPart part = message.getSOAPPart();
        SOAPEnvelope envelope = part.getEnvelope();
        SOAPBody body = envelope.getBody();
        QName name = new QName("命名空间", "HIPMessageServer", "tem");
        SOAPBodyElement bodyElement = body.addBodyElement(name);
        String s1 = "BOE0074";//Object是用来存储方法的参数
        String s2 = "<![CDATA[<Request>\n" +
                "    <Header>\n" +
                "        <SourceSystem>11</SourceSystem>\n" +
                "        <MessageID>11</MessageID>\n" +
                "    </Header>\n" +
                "<Body>\n" +
                "    <MedExamRt>\n" +
                "               <PATPatientID>101100000002</PATPatientID>\n" +
                "        </MedExamRt>\n" +
                "    </Body>\n" +
                "</Request>]]>";
        QName input1 = new QName("http://namespace", "input1", "tem");
        QName input2 = new QName("http://namespace", "input2", "tem");
        bodyElement.addChildElement(input1).setValue(s1);
        bodyElement.addChildElement(input2).setValue(s2);
        message.writeTo(System.out);
        System.out.println();
        URLEndpoint destination = new URLEndpoint(endpoint);
        SOAPMessage reply = connection.call(message, destination);
        TransformerFactory transformerFactory =
                TransformerFactory.newInstance();
        Transformer transformer =
                transformerFactory.newTransformer();
        Source sourceContent = reply.getSOAPPart().getContent();
        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
        System.out.println();
        connection.close();

3. 解析soap消息并处理其乱码

SOAPMessage reply = connection.call(message, destination);
        org.w3c.dom.Document document1 = reply.getSOAPPart().getEnvelope().getOwnerDocument();
        StringWriter output1 = new StringWriter();
        TransformerFactory.newInstance().newTransformer().transform( new DOMSource(document1), new StreamResult(output1));
        System.out.println("原始为"+output1);
        System.out.println("字符串为"+output1.toString());
        String ss = output1.toString();
        String sw = ss.replace("&lt;","<");
        String sri = sw.replace("&gt;",">");
        System.out.println("转换后的字符串"+sri);
        String tems1 = sri.toString().replace("<![CDATA[","");
        String tempst1 = tems1.replace("]]>","");
        System.out.println("字符串为"+tempst1);
        StringReader sr1 = new StringReader(tempst1);
        InputSource is1 = new InputSource(sr1);
        DocumentBuilderFactory factory2 = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder1=factory2.newDocumentBuilder();
        org.w3c.dom.Document doc1 = builder1.parse(is1);
        System.out.println(doc1);
        System.out.println("成功获取"+doc1.getElementsByTagName("MedExamID").item(0).getTextContent());
