如何将SOAPBody转换为String

Question

我想将SOAPBody转换为String.最好的方法是什么？我应该先将其转换为xml然后将其转换为String,或者我们可以将其转换为String.

Answer 1

从SOAPMessage开始时,最简单的方法是使用该writeTo方法:

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).

如果从SOAPBody开始,那么你可能应该使用XML API,看看SOAPBody是一个org.w3.dom.Element,最简单的方法可能是使用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,但那应该非常接近).

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.

我认为这可能有帮助 -

private String convertToString (SOAPBody message) throws Exception{
   Document doc = message.extractContentAsDocument();
   StringWriter sw = new StringWriter();
   TransformerFactory tf = TransformerFactory.newInstance();
   Transformer transformer = tf.newTransformer();
   transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
   transformer.setOutputProperty(OutputKeys.METHOD, "xml");
   transformer.setOutputProperty(OutputKeys.INDENT, "yes");
   transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
   transformer.transform(new DOMSource(doc), new StreamResult(sw));
   return sw.toString();
  }
