Apache AXIS2 发送大型 DIME 附件

Question

我目前正在开发一个网络服务，使用 DIME 将大型 pdf 文件从客户端发送到服务器。我正在使用 apache axis2 实现来支持 Web 服务。我一直想让该服务正常工作，但当我尝试发送大于 1MB 的附件时出现问题，然后出现异常。我的猜测是，我可能必须在发送附件之前将其分块，但我不知道在哪里可以控制它，而且我想也许这会是另一个。下面是上传文件的客户端代码

public class PdfDriver
{

/**
 * @param args
 * @throws IOException
 */
public static void main(String[] args) throws IOException
{
    // TODO Auto-generated method stub
    testAddGroup();

}

public static void testAddGroup() throws IOException
{

    try
    {
        PdfMail_ServiceLocator locator = new PdfMail_ServiceLocator();
             locator.setPdfMailSOAPEndpointAddress("http://localhost:80/services/PdfMailSOAP");

        PdfMail_PortType stub = locator.getPdfMailSOAP();

        PdfMailSOAPStub server = null;
        server = (PdfMailSOAPStub) stub;

        //Test uploading pdf
        server._setProperty(Call.ATTACHMENT_ENCAPSULATION_FORMAT,   Call.ATTACHMENT_ENCAPSULATION_FORMAT_MTOM);

        FileDataSource ds = new FileDataSource("/test.zip");
        DataHandler dh = new DataHandler(ds);

        server.addAttachment(dh);



        System.out.println(server.getTimeout());
        Calendar cal = Calendar.getInstance();
        long x = cal.getTimeInMillis();
        System.out.println("Server: Start receive@ "+  "\n" +   server.sendPdf("test.zip") + "\nServer: Finished receive ");



    }
    catch (ServiceException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


   }
} 

这是我用来在服务器端处理附件的代码

public java.lang.String sendPdf(java.lang.String pdfToSend) throws java.rmi.RemoteException
{
    String result = "";
    AttachmentPart[] attachments = null;
    try
    {
        attachments = getAttachments();
    }
    catch (Exception e1)
    {
        result = "null attachments getAttachments exception";
        e1.printStackTrace();
    }
    if (attachments != null)
    {
        for (int i = 0; i < attachments.length; i++)
        {
            AttachmentPart attachment = attachments[i];
            try
            {
                File file = new File(pdfToSend);
                InputStream in = attachment.getDataHandler().getInputStream();
                OutputStream out = new FileOutputStream(file);
                byte[] buffer = new byte[8192];
                int len;

                while ((len = in.read(buffer)) > 0)
                    out.write(buffer, 0, len);

                out.close();
                in.close();

                result += "File saved on the server\nFile Size : " + (file.length() / 1048576) + "MB \nSend Type : " + this.receivedType;

            }
            catch (IOException e)
            {
                result += "exception IO";
                e.printStackTrace();
            }
            catch (SOAPException e)
            {
                result += "SOAP exception";
                e.printStackTrace();
            }
        }
    }
    return result;
}

private AttachmentPart[] getAttachments() throws Exception
{
    MessageContext msgContext = MessageContext.getCurrentContext();
    Message message = msgContext.getRequestMessage();
    Attachments attachmentsimpl = message.getAttachmentsImpl();
    if (null == attachmentsimpl)
    {
        return new AttachmentPart[0];
    }
    int attachmenstCount = attachmentsimpl.getAttachmentCount();
    this.receivedType = attachmentsimpl.getSendType();
    AttachmentPart attachments[] = new AttachmentPart[attachmenstCount];

    Iterator<AttachmentPart> iter = attachmentsimpl.getAttachments().iterator();
    int count = 0;
    while (iter.hasNext())
    {
        AttachmentPart part = iter.next();
        attachments[count++] = part;
    }
    return attachments;

}

如果有人知道问题会导致大于 1MB 的文件出现 AxisFault，我将不胜感激。谢谢。

Answer 1

Axis2不支持DIME，请参阅上一个问题：
Java 客户端使用 DIME 附件调用 WSE 2.0

Answer 2

确切地知道异常是什么会有所帮助，但如果只是盲目猜测，您的 Apache 配置可能会限制上传（http post）大小。
