MTOM - 测试文件内容

Question

我有一个使用 MTOM 接收文件的 web 服务（在 jBoss 7.4 中运行）。

客户端（另一个应用程序。用于测试的 SoapUI）发送文件，我们接收它。

创建一个测试的最佳方法是什么，该测试执行一个附加文件的请求，然后检查附件是否真的收到（比较二进制数据）。

我应该怎么做？

几天前我为我的应用程序编写了一个类似的测试用例。 是的，它比较了实际内容。 下面是源代码。这可能对您有所帮助。

/**
 * Compares the contents of SOAP attachment and contents of actual file used for creating the attachment
 * Useful for XML/HTML/Plain text attachments
 * @throws SOAPException
 * @throws IOException
 * @throws IllegalArgumentException
 * @throws ClassNotFoundException
 */
@Test
public void testSetAndGetContentForTextualAttachment() throws SOAPException, IOException,
        IllegalArgumentException, ClassNotFoundException {

    SOAPMessage soapMessage = MessageFactory.newInstance().createMessage();
    SOAPMTOMMessageImpl soapImpl = new SOAPMTOMMessageImpl(soapMessage);
    SOAPPart part = soapMessage.getSOAPPart();

    SOAPEnvelope envelope = part.getEnvelope();
    SOAPBody body = envelope.getBody();
    SOAPBodyElement element = body.addBodyElement(envelope.createName(
            "test", "test", "http://namespace.com/"));

    // Create an Attachment from a file
    File attachmentFile = new File ("C:\\temp\\temp.txt");

    // get the expected contents from a file
    StringBuffer expectedContent = new StringBuffer();
    String line = null;
    BufferedReader br = new BufferedReader(new FileReader(attachmentFile));
    while((line = br.readLine()) != null){
        expectedContent = expectedContent.append(line);
    }

    // create attachment
    // Uses my application's custom classes, but you can use normal SAAJ classes for doing the same.    

    Attachment fileAttachment = soapImpl.createAttachmentFromFile(attachmentFile, "text/plain");
    // content id will be used for downloading the attachment
    fileAttachment.setContentID(attachmentFile.getName()+".restore");

    // create MTOM type soap object from this attachment
    QName fileSoapAttachmentQname = new QName("http://namespace.com/", "AttachFileAsSOAPAttachmentMTOM", "AttachmentElement");
    soapImpl.setXopQname(fileSoapAttachmentQname);
    soapImpl.addAttachmentAsMTOM(fileAttachment, element);

    // Extract the attachment and cross check the contents
    StringBuffer actualContent = new StringBuffer();
    List<Attachment> attachments = soapImpl.getAllAttachments();
    for(int i=0; i<attachments.size(); i++){
        AttachmentPart attachmentPart = ((AttachmentImpl) attachments.get(i)).getAttachmentPart();
        BufferedInputStream bis = new BufferedInputStream (attachmentPart.getDataHandler().getInputStream());

        byte[] data = new byte[1024];
        int numOfBytesRead = 0;
        while(bis.available() > 0){
            numOfBytesRead = bis.read(data);
            String tmp = new String(data,0,numOfBytesRead);
            actualContent = actualContent.append(tmp);
        }
        bis.close();
    }
    try {
        Assert.assertEquals(true,
                (expectedContent.toString()).equals(actualContent.toString()));
    } catch (Throwable e) {
        collector.addError(e);
    }

}

要在服务器端进行类似的验证，您可以使用 Content-length 标头值进行比较。或者您可以添加一个额外的属性来确定预期的附件大小或校验和类型。
