            bodyElement.addChildElement(paramKey).addTextNode(paramValue); 

        }

 

        //保存message

        message.saveChanges(); 

        logger.debug("\\nREQUEST:\\n" + message);

        

        //发送请求获取相应

        String destination = HIS_SERVICE_URL; 

        SOAPMessage reply = connection.call(message, destination); 

        logger.debug("\\nREQUEST:\\n" + message);

        //Create the transformer 

        TransformerFactory transformerFactory = TransformerFactory.newInstance(); 

        Transformer transformer = transformerFactory.newTransformer(); 

       

        //提取响应的xml

        Source sourceContent = reply.getSOAPPart().getContent(); 

        

        //Set the output for the transformation 

        StreamResult result = new StreamResult(System.out); 

        transformer.transform(sourceContent, result); 

        logger.debug("\\nRESPONSE:\\n" + result); 

        

        String response = reply.getSOAPBody().getTextContent();     

        
        return response;

返回的response可以解析成dom对象
