Question

我正在尝试使用MTOM和ADB从我的Axis2 webservice服务器下载文件。如果我不在服务器端和客户端都启用MTOM，我可以下载该文件。任何建议或代码示例都会很好：）

客户端

ServerWSStub stub = new ServerWSStub();
stub._getServiceClient().getOptions().setProperty(Constants.Configuration.ENABLE_MTOM,Constants.VALUE_TRUE);

服务器端axis2.xml

<parameter name="enableMTOM">optional</parameter>

这是我的服务器

public DataHandler download(String konum) throws Exception {
        System.out.println("The filePath for download: " + konum);
        FileDataSource dataSource = new FileDataSource(konum);
        DataHandler datahandler = new DataHandler(dataSource);

        OMFactory fac = OMAbstractFactory.getOMFactory();
        OMNamespace ns = fac.createOMNamespace("http://benim.projem.org/dosya", "dosyam");
        OMText textData = fac.createOMText(datahandler, true);
        OMElement ele = fac.createOMElement("sonuc", ns);
        ele.addChild(textData);
        System.out.println(ele);
        return datahandler;

这是我的客户

ServerWSStub stub = new ServerWSStub();          

//stub._getServiceClient().getOptions().setProperty(Constants.Configuration.ENABLE_MTOM,Constants.VALUE_TRUE); 

//when uncommented i get java.lang.NoClassDefFoundError: org/apache/james/mime4j/MimeException 
//while trying to invoke _operationClient.execute(true); in ServerWSStub 
//I guess it is because of wrong unparsing


Download download = new Download();
download.setKonum(konum);
try {
    DownloadResponse downloadResponse = stub.download(download);
    DataHandler dh =(DataHandler) downloadResponse.get_return();
    File file = new File("C:/dosya/"+fileNameType);

    if (!file.getParentFile().exists())
        file.getParentFile().mkdirs();
    if(!file.exists()){
        file.createNewFile();
    }
    FileOutputStream fileOutputStream = new FileOutputStream(file);

    dh.writeTo(fileOutputStream);
    fileOutputStream.flush();
    fileOutputStream.close();
} catch (ServerWSExceptionException e) {
    e.printStackTrace();
}

任何

我猜终于得到了解决方案。在客户端获取整个文件之前，Stream关闭了，这就是为什么我首先使用了getOptions（）。setTimeOutInMilliSeconds（10000）方法，但它也没用，然后在我评论的Stub文件中

_messageContext.getTransportOut().getSender().cleanup(_messageContext);//look for the method's finally part

部分，以便在大型文件传输期间，流没有被关闭，我可以下载整个文件，没有任何愚蠢的例外：）

只需将 apache-mime4j-core-0.7.2.jar 添加到服务（服务器）端的 WEB-INF / lib 即可。可以找到jar here。
