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，我们会收到它。

创建测试的最佳方法是什么，该测试执行附加文件的请求，然后检查附件是否确实已收到（比较二进制数据）。

我应该怎么做？

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);
    }

}

若要在服务器端进行类似的验证，可以使用内容长度标头值进行比较。或者，您可以添加额外的属性来确定预期的附件大小或校验和类型。
