Question

美好的一天。我已将org.apache.commons.net.ftp.FTP导入到我的项目中，并且在将zip文件上传到FTP时遇到了一些问题。当它上传小文件（<100MB）时，它工作正常。但是当涉及到更大的文件（> 500MB）时，它将在那里停止，而不返回并执行剩余的操作，即使文件被传输到服务器也是如此。以及传输完成后函数/ FTP如何确认？无论如何要检查它吗？

public class zipFTP
{
public boolean uploadFile(String ht, String usr, String ps, String fpath, String uploadloc)
{
    FTPClient client = new FTPClient();
    FileInputStream fis = null;
    writeLog nLog = new writeLog();
    String channel = "FTP";
    boolean completed = false;
    //client.setBufferSize(1048576);
    client.setControlKeepAliveReplyTimeout(300);

    //System.out.println(client.getBufferSize());
    try
    {
        nLog.writeToLog(dumptoFTP.filename, channel, "Uploading...");

        client.connect(ht);
        client.login(usr, ps);
        client.enterLocalPassiveMode();
        client.setFileType(FTP.BINARY_FILE_TYPE);

        fis = new FileInputStream(fpath);
        completed = client.storeFile(uploadloc, fis);
        //client.completePendingCommand(); //to complete the transaction entirely
        if(completed) 
        {
         if (dumptoFTP.isSysLog)
            System.out.println("File uploaded");
            nLog.writeToLog(dumptoFTP.filename, channel, "File uploaded");
        }

        fis.close();
    }
    catch (IOException e)
    {
        e.printStackTrace();
        if (dumptoFTP.isSysLog)
            System.out.println("Upload failed");
        nLog.writeToLog(dumptoFTP.filename, channel, "Upload failed");
        nLog.writeToLog(dumptoFTP.filename, channel, e.toString());
    }
    finally 
    {
        try
        {
            if(client.isConnected())
            {
                client.logout();
                client.disconnect();
            }
        } 
        catch (IOException ex) 
        {
            ex.printStackTrace();
        }
    }

    return completed;
}

}

Answer 1

结束，setBufferSize()可以解决问题

Java FTP上传已完成但未返回
