有时我得到流关闭有时我没有。为什么我会这样？

Question

我有这样的代码：

AxiomSoapMessage message = (AxiomSoapMessage)webServiceMessage; 

SoapHeader soapHeader = message.getSoapHeader();
SOAPMessage soapMessage = message.getAxiomMessage();

TransportContext transContext = TransportContextHolder.getTransportContext();

HttpServletConnection connection = (HttpServletConnection)transContext.getConnection();
HttpServletRequest httpRequest = connection.getHttpServletRequest();

InputStream inputStream = httpRequest.getInputStream();

SniffedXmlInputStream sniffedXmlInputStream = new SniffedXmlInputStream(inputStream);

String encoding = sniffedXmlInputStream.getXmlEncoding();
sniffedXmlInputStream.close();

String soapVersion = message.getVersion().toString();       

ByteArrayOutputStream baos = new ByteArrayOutputStream();

**soapMessage.serialize(baos);** //THIS LINE

这是接收Spring ws的 WebServiceMessage 的类的一部分，我从中提取 SOAPMessage ，如上所示。

在上面代码中标有“THIS LINE”的粗体行中，我“有时”得到以下异常

 org.springframework.integration.MessageHandlingException: 
    org.apache.axiom.om.OMException: 
       javax.xml.stream.XMLStreamException: 
          ParseError at [row,col]:[1,4090] Message: Stream closed

任何解决方案？

由于XML无效，可能会发生javax.xml.stream.XMLStreamException。打印XML并查看它是否针对DTD或XSD进行验证。
