看了SOAP消息分析以後,你們對soap消息應該有了一個初步的認識,那麼怎樣本身編寫一個soap消息呢?
先來建立一個簡單的soap消息:ruby
@Test
public void test1(){
try {
//1.建立消息工廠
MessageFactory factory = MessageFactory.newInstance();
//2.根據消息工廠建立SoapMessage
SOAPMessage message = factory.createMessage();
//3.建立SOAPPart
SOAPPart part = message.getSOAPPart();
//4.獲取SOAPEnvelope
SOAPEnvelope envelope = part.getEnvelope();
//5.能夠經過信封有效的獲取header和body的內容
SOAPBody body = envelope.getBody();
//6.根據QName建立相應的節點,QName是帶有命名空間的節點
//這裏是建立一個<lenve:add xmlns="http://www.lenve.test">
QName qname = new QName("http://www.lenve.test", "add", "lenve");
body.addBodyElement(qname);
message.writeTo(System.out);
} catch (SOAPException | IOException e) {
e.printStackTrace();
}
}
輸出:markdown
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><lenve:add xmlns:lenve="http://www.lenve.test"/></SOAP-ENV:Body></SOAP-ENV:Envelope>
和咱們在上一篇中用tcpmon捕獲的消息一致,沒問題。但是這個body裏邊是空的,那麼怎樣給body中添加內容呢?tcp
@Test
public void test2(){
try {
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
SOAPPart part = message.getSOAPPart();
SOAPEnvelope envelope = part.getEnvelope();
SOAPBody body = envelope.getBody();
QName qname = new QName("http://www.lenve.test", "add", "lenve");
SOAPBodyElement element = body.addBodyElement(qname);
element.addChildElement("a").setValue("3");
element.addChildElement("b").setValue("4");
message.writeTo(System.out);
} catch (SOAPException | IOException e) {
e.printStackTrace();
}
}
輸出:spa
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><lenve:add xmlns:lenve="http://www.lenve.test"><a>3</a><b>4</b></lenve:add></SOAP-ENV:Body></SOAP-ENV:Envelope>
<a>3</a><b>4</b>都已經順利添加進去了。
