Question

我正在使用cxf 2.7.7并使用带有https的MTOM ...它可以正常使用cxf java客户端。但是，当我通过SOAP UI客户端发送消息时，在服务器端（在我的端点实现类中），我尝试访问Datahandler对象的任何方法（请参阅下面的删节代码）然后我得到java.lang.NullPointerException在org.apache.cxf.attachment.LazyDataSource中。请注意，调用任何.getXXX方法都会产生异常（这些调用转换为对LazyDataSource.getXXX方法的相应调用......看起来像LazyDataSource为null）当我通过Java客户端发送请求时，这不会发生。仅在我使用SOAPUI请求时才会发生 @WebService（targetNamespace =“http://webservice.dcca.dell.com”， portName =“ObjectMTOMService”，serviceName =“ObjectMTOMServiceService”） public class ObjectMTOMServiceImpl实现ObjectMTOMService {

@Resource 
WebServiceContext wsContext; 

public ObjectStoreResp uploadObject(ObjectStoreReq objectReqParam) { 

    DataHandler objHandler = objectReqParam.getObjData(); 

    try { 

                    if (objHandler != null) 
                    { 

                    String objName=objHandler.getName(); 

                    String contentType=objHandler.getContentType(); 

                    InputStream iStream= objHandler.getDataSource().getInputStream(); 

                     } 
          catch (Exception e) { 
                    e.printStackTrace(); 
                    respParam.setRespCode(-1); 
                    return (respParam); 
            } 
}

我看到的例外情况如下

java.lang.NullPointerException

    at javax.activation.DataHandler.getName(DataHandler.java:191)

SOAPUI发送的消息如下＆lt;＆lt;我已接近这一点 - 从SOAPUI日志复制和粘贴＆gt;＆gt;

欢迎任何投入。如果有人尝试过使用SOAPui客户端和Axis 2.7.X组合的MTOM，请告诉我

非常感谢你的帮助

这个问题是因为我在SOAPUI中使用了错误的设置，即将数据作为Null发送。我认为这是一个CXF错误，它给出了空指针异常。应该有一种更安全的方式来报告我有一个空附件。无论如何，问题是我是如何解决的。

以下链接，确实提供了信息，但恕我直言，它有点含糊不清（或者可能是我没有解释它:-( - 不得不多次阅读

http://www.soapui.org/SOAP-and-WSDL/adding-headers-and-attachments.html

我在SOAP UI中指定请求SOAP消息的错误方法是

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"  
xmlns:typ="http://webservice.dcca.dell.com/types">
    <soapenv:Header/>
    <soapenv:Body>
      <typ:objectStoreReq>
         <typ:ObjData>cid:183942097334</typ:ObjData>
         <typ:objMetadata>
            <typ:objName>img</typ:objName>
            <typ:organizationName>Dell</typ:organizationName>
         </typ:objMetadata>
      </typ:objectStoreReq>
   </soapenv:Body>
</soapenv:Envelope>

正确的方法是（注意，不是在“Objdata”元素中填充部分id-使用“cid：id”将其作为base64编码发送，我们必须使用href指定XOP Include元素引用第二个Mime-Part

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"  
    xmlns:typ="http://webservice.dcca.dell.com/types">
        <soapenv:Header/>
        <soapenv:Body>
          <typ:objectStoreReq>
             <typ:ObjData>
            <inc:Include 
            href="cid:myImage.jpg" 
            xmlns:inc="http://www.w3.org/2004/08/xop/include"
            />
             </typ:ObjData>
             <typ:objMetadata>
                <typ:objName>img</typ:objName>
                <typ:organizationName>Dell</typ:organizationName>
             </typ:objMetadata>
          </typ:objectStoreReq>
       </soapenv:Body>
</soapenv:Envelope>

有了这个，我的SOAP-UI消息非常适合我的服务:-)
