使用SAAJ发送和接收SOAP消息

Web 服务的基础是以标准格式发送和接收消息(SOAP XML)，这样所有系统都可以理解消息.JAVA saaj提供了一组API可以用来创建 SOAP 连接,生成 SOAP 消息,发送请求消息和得到返回消息.

http://blog.csdn.net/kkdelta/archive/2009/03/13/3987591.aspx介绍的proxy方式以及dispatch方式最终也是通过saaj发送和获取返回的.

例子:

try {

// First create the connection
SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnFactory.createConnection();
// Next, create the actual message
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage message = messageFactory.createMessage();

// Create objects for the message parts
SOAPPart soapPart = message.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPBody body = envelope.getBody();

// Populate the body Create the main element and namespace
//SOAPElement bodyElement = body.addChildElement(envelope.createName("queryPeopleByID", "ns1",
// "http://test.cxfws.com/"));
// Add content
//bodyElement.addTextNode("1231ss");

StreamSource xmlSource1 = new StreamSource(MsgUtil.readMsgAsStream("com/test/jaxws/dispatch/req.xml"));
soapPart.setContent(xmlSource1);

// Save the message
message.saveChanges();
// Check the input

message.writeTo(System.out);
System.out.println();

// Set the destination
String destination = "http://localhost:8080/prjCXFWS/services/SimpleServicePort";
// Send the message
SOAPMessage reply = connection.call(message, destination);

// Create the transformer
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
// Extract the content of the reply
Source sourceContent = reply.getSOAPPart().getContent();


StreamResult result = new StreamResult(new ByteArrayOutputStream());
transformer.transform(sourceContent, result);

System.out.println(((ByteArrayOutputStream)result.getOutputStream()).toString());

// Close the connection
connection.close();

} catch (Exception e) {
e.printStackTrace();
}
