使用 Java 将 SOAP 消息格式转换为套接字消息格式，反之亦然

Question

我目前正在使用 Java 研究 SOAP 消息格式到套接字消息格式的转换，反之亦然。

我需要它来重用读取套接字格式消息的旧系统以连接到发送和接收 SOAP 消息格式的网站。

我应该怎么做？我应该考虑文本处理吗？

示例套接字到 SOAP

插座

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Interface Code="20" 
      <Transaction Txn="01880120121024000001" CD="01880120121024000001001" 
     Date="2012-10-24 17:27:25"  BirthDate="1983-03-27" Code="8110009000000720" Type="0"/>
</Interface>

香皂

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
 <soapenv:Body>
  <webRequest xmlns="http://____________">
   <arg0 xmlns="">&lt;?xml version="1.0" encoding="UTF-8"
    standalone="yes"?>&lt;Interface xmlns="http://____________"
    Version="1.0" Code="20" Txn="123" CD="456">&lt;Info
    BirthDate="1983-03-27" Code="1234" Type="0" />&lt;/Interface></arg0>
  </webRequest>
 </soapenv:Body>
</soapenv:Envelope>

套接字消息是 SOAP 消息的 XML 转义主体。您不需要额外的库，因为 parsing SOAP requests.

有 javax 类

SOAP 到套接字很简单：

String message = "<?xml version='1.0' encoding='UTF-8'?>\n<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">\n <soapenv:Body>\n  <webRequest xmlns=\"http://____________\">\n   <arg0 xmlns=\"\">&lt;?xml version=\"1.0\" encoding=\"UTF-8\"\n    standalone=\"yes\"?>&lt;Interface xmlns=\"http://____________\"\n    Version=\"1.0\" Code=\"20\" Txn=\"123\" CD=\"456\">&lt;Info\n    BirthDate=\"1983-03-27\" Code=\"1234\" Type=\"0\" />&lt;/Interface></arg0>\n  </webRequest>\n </soapenv:Body>\n</soapenv:Envelope>";
InputStream is = new ByteArrayInputStream(message.getBytes());
SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);
System.out.println(request.getSOAPBody().getTextContent());

SOAP 的套接字更复杂，因为我们需要创建 webRequest 包装元素：

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
docFactory.setNamespaceAware(true); // webRequest needs a namespace
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();

Document doc = docBuilder.newDocument();
Element root = doc.createElementNS("http://____________", "webRequest");
doc.appendChild(root);

Element argElement = doc.createElement("arg0");
root.appendChild(argElement);
String message = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n<Interface Code=\"20\" \n      <Transaction Txn=\"01880120121024000001\" CD=\"01880120121024000001001\" \n     Date=\"2012-10-24 17:27:25\"  BirthDate=\"1983-03-27\" Code=\"8110009000000720\" Type=\"0\"/>\n</Interface>";
argElement.setTextContent(message);

SOAPMessage request = MessageFactory.newInstance().createMessage();
request.getSOAPBody().addDocument(doc);
request.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");
request.writeTo(System.out);

使用 Java 将 SOAP 消息格式转换为套接字消息格式，反之亦然
