伙计们！我正在尝试获取SOAPBody对象请求的字符串。我正在使用axis 2和Tomcat 9进行Web服务。

public static String getXMLSoapBody()
{
   log.getLogger().debug("TEST - getXmlSoapBody - START");
   String soapBody;
   SOAPBody body;
   MessageContext messageContext = MessageContext.getCurrentMessageContext();
   try {
      SOAPEnvelope env  = messageContext.getEnvelope();
      body = env.getBody();
   }
   catch(Exception e)
   {
      log.getLogger().error("SOAP Exception :" + e.toString());
      e.printStackTrace();

      return null;
   }

   soapBody = body.toString();

return soapBody;

但当我发送请求时，我收到此错误：catalina.out:10：41：26.935 [http-nio-8080-exec-2]错误org.apache.axis2.transport.http.AxisServlet - processAxisFault（）从MessageContext示例中发现一个空HTTP状态，将HttpServlet响应状态设置为：axis2.http.response.state
我的日志文件：2022年12月1日10：41：26 [http-nio-8080-exec-2]（TransUtils.java：287）调试测试-获取XmlSoapBody-开始
我试图查看它的完整堆栈跟踪，但是当我尝试使用try/catch来获取soapBody = body.toString（）;行我收到此错误，但前一个错误不是：

org.apache.axiom.om.NodeUnavailableException

    at uk.co.celesio.orders.server.TransUtils.getXMLSoapBody(TransUtils.java:304)

我的要求：

<?xml version='1.0' encoding='windows-1252'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soapenv:Body>
    <MyTestRequest xmlns="...">
      ...
    </MyTestRequest>
  </soapenv:Body>
</soapenv:Envelope>

尝试使用try/catch查看完整错误，还尝试记录此错误，但在这两种情况下，我都收到NodeUnavailableException
