【问题描述】：

这里是代码。

    Client.changeWorkingDirectory("./Users");
    Client.changeWorkingDirectory("Users");
    Client.changeWorkingDirectory(UsernameString);
    Client.changeWorkingDirectory("ActiveSells");
    Client.setBufferSize(1024*1024);
    Object earray[] = new Object[5];      //In my code earray is actually something
    Out = new ByteArrayOutputStream(); 
    OOS = new ObjectOutputStream(Out);
    OOS.writeObject(earray);
    RetrievedItem = Out.toByteArray();         //RetrievedItem is a ByteArray
    System.out.println(RetrievedItem.length);  //This tells me 401257
    OOS.flush();
    OOS.close();
    OOS = new ObjectOutputStream(Client.storeFileStream(((String)array[0]).toString()));
    OOS.writeObject(RetrievedItem);
    OOS.flush();
    OOS.close();
    Client.completePendingCommand();
    System.out.println("GetResponse");
    String response = Client.getReplyString();
    System.out.println(response);
    InputStream FIS = Client.retrieveFileStream(((String)array[0]).toString());
    String response2 = Client.getReplyString();
    System.out.println(response2);  //This tells me 390.7kb to download
    OIS = new ObjectInputStream(FIS);
    RetrievedItem = ((byte[])OIS.readObject());  //Gives me EOF
    System.out.println(RetrievedItem.toString());  //From here down the code is skipped
    In = new ByteArrayInputStream(RetrievedItem);  
    OIS = new ObjectInputStream(In);
    Object retrievedfinally = OIS.readObject();
    System.out.println(retrievedfinally);
    In.close();


    return FragMan;

服务器上的文件大小为 391kb。我不确定问题是在上传对象还是在下载对象。有人对为什么会出现故障有任何建议吗？

这是错误

【解决方案1】：

所以显然这是一个无法解决的问题。我试图上传的对象是一组对象，最后一个对象是图像。似乎是 Apache commons 中的一个小故障，它没有上传图像的最后一位，从而破坏了它。我已经切换到 ftp4j 并且可以正常工作。
