可以使用Amadeus的Web服务“Divide PNR”来分离已婚航段。下面是一个示例的代码：

SOAPMessage response = null;
SOAPConnectionFactory soapConnFactory;
SOAPConnection soapConn;
String endpoint = "https://nodeD1.test.webservices.amadeus.com/"; // Amadeus Web服务的端点
String soapAction = "1ASIWK?wsdl"; // SOAP操作的标识

// 创建SOAP工厂和连接对象
soapConnFactory = SOAPConnectionFactory.newInstance();
soapConn = soapConnFactory.createConnection();

// 创建SOAP消息对象并设置消息体
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
soapMessage.getSOAPHeader().setPrefix("soapenv");
soapMessage.getSOAPBody().setPrefix("soapenv");
SOAPElement soapEnv = soapMessage.getSOAPBody().addChildElement("DividePNR", "m");
soapEnv.addChildElement("reservationInfo", "m").addTextNode("123456");

// 发送SOAP请求并获取响应
response = soapConn.call(soapMessage, endpoint + soapAction);

// 解析响应数据
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.writeTo(out);
String strResponse = out.toString();
