推荐答案
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")
（上面，我假设您的SAAJ实现将使用UTF-8，您可能想要检查）。
(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，看到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();
（对不起，我这里没有我的IDE，无法检查这是否编译，但是应该非常接近）。
(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（SOAP With Attachment）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.
