Question

我正在尝试创建一个soapMessage，以便稍后传入以下代码片段：

SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnectionFactory.createConnection();
SOAPMessage response = connection.call(message, url);

但是，我收到一个空（null）响应：[SOAP-ENV：Body：null]。

当我执行以下操作时（在连接调用之前）：

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

当它们应该相同时，我得到两个不同的答案，对吗？

第一个系统打印ln给了我[SOAP-ENV：Body：null]，而另一个实际上给了我创建的soap消息（writeTo）。

任何想法为什么？

完整代码：

MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
SOAPElement tvl = envelope.addAttribute(new QName("xmlns:tvl"), "http://some.url.com/");
SOAPBody body = message.getSOAPBody();
QName bodyText = new QName("tvl:searchAirings");
SOAPBodyElement bodyElement = body.addBodyElement(bodyText); 
QName fromTag = new QName("from");
SOAPElement from = bodyElement.addChildElement(fromTag);
from.setValue("2012-11-02T14:00:00-4:00");

QName toTag = new QName("to");
SOAPElement to = bodyElement.addChildElement(toTag);
to.setValue("2012-11-02T18:00:00-4:00");

QName networkTag = new QName("network");
SOAPElement network = bodyElement.addChildElement(networkTag);
network.setAttribute("id", "n501");
network.setAttribute("language", "es");

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

Answer 1

System.out.println(message.getSOAPBody()); =＆gt;这应该只打印SOAP信封的主体。

message.writeTo(System.out); =＆gt;这应该打印完整的SOAP消息，即信封，标题和正文。

Answer 2

您可以通过将响应写入ByteArrayOutputStream

来解决此问题

SOAPMessage soapResponse = soapConnection
        .call(createSOAPRequest(), url);

ByteArrayOutputStream byteOutStream = new ByteArrayOutputStream();
soapResponse.writeTo(byteOutStream);
String res = new String(byteOutStream.toByteArray());
System.out.println("Response \n"+res);

SOAP getBody方法vs writeTo
