        ftpClient.connect(ftp_server,port);
        ftpClient.login(ftp_username,ftp_password);

        System.out.println("listFiles--->message");
        FTPFile[] message = ftpClient.listFiles("/message");
        System.out.println("list-message"+message.length);
        System.out.println("listFiles--->order");
        FTPFile[] order = ftpClient.listFiles("/order");
        System.out.println("list-order"+order.length);

        String path = ftpClient.printWorkingDirectory();
        System.out.println("path :"+path);

    }
    catch (Exception e)
    {
        System.out.println(e);
    }
}

在计划中，我检查了活动用户，然后将用户发送到上述函数以获取他们在 FTP 服务器内的两个文件夹“消息”和“订单”。 但是在 FTPFile[] message = ftpClient.listFiles("/message"); 行 我收到错误。

在JobSchedular上执行DailyTask函数

DateFormat dateFormater2 = new SimpleDateFormat("dd_MM_yyyy_HH_mm");

FTPClient ftp = null;

public void performDailyTask(){

System.out.println("**************************performDailyTask**************************");

    List<User> userList = userService.findAllClient();

    if(!userList.isEmpty())
    {
        List<User> newUserList=userService.findAllActiveClient(userList);
        if(!newUserList.isEmpty()){

            for(User user : newUserList)
            {
                copyFileFromFTPtoAWS_v2(user);
            }
        }
    }
}

新错误

解决方法

    ftpClient.enterLocalPassiveMode();
    ftpClient.type(FTP.BINARY_FILE_TYPE);

FTP 连接后的这两行解决了我的问题。因为除了日志文件上的一些警告之外，我没有收到任何错误。
