Java SOAP - 在Body和ChildElement操作方面需要幫助

Question

我想在java中編寫一些代碼，以瞭解有關使用WSDL和SOAP編碼的更多信息。

例如，給定：

'<'to:checkAccount xmlns:to="http://foo"> 
     '<'to:id> test '<'/to:id> 
     '<'to:password> test '<'/to:password> 
'<'to:checkAccount >"
 

'<'element name="checkAccountResponse"> '<'complexType> '<'sequence> '<'element name="checkAccountReturn" type="impl:account"/> '<'/sequence> '<'/complexType> '<'/element>
 

'<'complexType name="account"> '<'sequence> '<'element name="active" type="xsd:boolean"/> '<'element name="name" type="xsd:string"/> '<'/sequence> '<'/complexType>
 

我的代碼看起來像這樣的時刻：

//create the message 
      String endpoint = "http://foo/someAPI"; 

      MessageFactory factory = MessageFactory.newInstance(); 
      SOAPMessage message = factory.createMessage(); 


      SOAPPart soapPart = message.getSOAPPart(); 
      SOAPEnvelope envelope = soapPart.getEnvelope(); 
      SOAPHeader header = message.getSOAPHeader(); 

      //adding to the body 
      SOAPBody body = message.getSOAPBody(); 
      SOAPFactory soapFactory = SOAPFactory.newInstance(); 
      Name bodyName = soapFactory.createName("checkAccount","to","http://foo"); 
      SOAPElement bodyElement = body.addBodyElement(bodyName); 

      //add the ID child elements 
      soapFactory = SOAPFactory.newInstance(); 
      Name childName = soapFactory.createName("id","to","http://foo"); 
      SOAPElement symbol = bodyElement.addChildElement(childName); 
      symbol.addTextNode("test"); 

      //add password child element 
      soapFactory = SOAPFactory.newInstance(); 
      childName = soapFactory.createName("password","to","http://foo"); 
      symbol = bodyElement.addChildElement(childName); 
      symbol.addTextNode("test"); 


      //call and get the response 
      SOAPMessage response = sc.call(message,endpoint); 


      //print the response 
      SOAPBody responseBody = response.getSOAPBody(); 
      java.util.Iterator iterator = responseBody.getChildElements(bodyName); 
. 
. 
. 
//the response is blank so trying to iterate through it gives the exception

我運行此，我也得到任何回報，只是空白。我知道我的端點是正確的，以及checkAccount，id和密碼，因爲我已經在xmlSpy中測試過它並返回了賬戶狀態。

它必須是我試圖得到答覆的方式。有人可以給我一個提示嗎？

這就是我該怎麼做的。

MessageFactory factory = MessageFactory.newInstance();   
SOAPMessage message = factory.createMessage(); 
SOAPBody body = message.getSOAPBody(); 
SOAPElement checkAccEl = body 
    .addChildElement("checkAccount", "to", "http://foo"); 

SOAPElement idEl = checkAccEl 
    .addChildElement("id", "to", "http://foo"); 
idEl.addTextNode("test"); 

SOAPElement passwordEl = checkAccEl 
    .addChildElement("password", "to", "http://foo"); 
passwordEl.addTextNode("test"); 

// print out the SOAP Message. How easy is this?! 
ByteArrayOutputStream out = new ByteArrayOutputStream(); 
message.writeTo(out); 
System.out.println(out.toString()); 

您使用的命名空間「爲= http://foo」它是在元素上自動聲明的第一次 - checkAccount在這種情況下。當您再次使用相同的名稱空間時，XML將不需要再次聲明它，但會使用前綴。

輸出看起來像：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> 
    <SOAP-ENV:Header/> 
    <SOAP-ENV:Body> 
     <to:checkAccount xmlns:to="http://foo"> 
      <to:id>test</to:id> 
      <to:password>test</to:password> 
     </to:checkAccount> 
    </SOAP-ENV:Body> 
</SOAP-ENV:Envelope> 

這是你想要什麼，我認爲
