推荐答案
当从 SOAPMessage 开始时，最简单的方法是使用 writeTo 方法:
When starting from a SOAPMessage, the easiest way is to use the writeTo method :
ByteArrayOutputStream stream = new ByteArrayOutputStream();
soapMessage.writeTo(stream);
String message = new String(stream.toByteArray(), "utf-8")
(以上，我假设您的 SAAJ 实现将使用 UTF-8，您可能需要检查一下).
(Above, I assume your SAAJ implementation will use UTF-8, you'd probably want to check).
如果从 SOAPBody 开始，那么您可能应该使用 XML API，因为 SOAPBody 是一个 org.w3.dom.Element，最简单的方法可能是使用 TrAX :
If starting from a SOAPBody, then you probably should use XML APIs, seeing SOAPBody is a org.w3.dom.Element, the easiest way would probably be using TrAX :
SOAPBody element = ... // Whatever
DOMSource source = new DOMSource(element);
StringWriter stringResult = new StringWriter();
TransformerFactory.newInstance().newTransformer().transform(source, new StreamResult(stringResult));
String message = stringResult.toString();
(抱歉，我这里没有我的 IDE，无法检查它是否可以编译，但应该很接近).
(Sorry I do not have my IDE right here, can not check if this compiles, but that should be pretty close).
请注意:序列化的 SOAPMessage 可能不是原始 XML:它可能是 MIME 结构:如果 SOAPMessage 实际使用 SwA(带附件的 SOAP)或 MTOM.但是，SOAPBody 绝对是纯 XML.
Please note : A serialized SOAPMessage may not be raw XML : it might be a MIME structure : if the SOAPMessage actually uses SwA (SOAP With Attachment) or MTOM. However, SOAPBody is definitely pure XML.
