Java FTP上传

Question

我遇到了这个困扰我一周的问题，

我正在尝试使用 java 通过 ftp 上传文件 xml，没什么特别的。

经过几次网络搜索后，我决定使用 ftp4j 包，根据文档应该可以解决问题。

重点是这个 ftp 服务器实际上与 Filezilla 一起工作...

这些是我的几行代码：

    public void connect() {
    try {


        String[] con = client.connect(s);
        for (int i = 0; i < con.length; i++) {
            System.out.println(con[i]);
        }

        client.login(user, password);

        s = client.getHost();
        System.out.println(s);

        con = client.help();
        for (int i = 0; i < con.length; i++) {
            System.out.println(con[i]);
        }

        client.changeDirectory(sDir);
        s = client.currentDirectory();

        System.setProperty("ftp4j.passiveDataTransfer.useSuggestedAddress", "1");

        client.setPassive(true);

        System.out.println(client.isPassive());

        client.setType(FTPClient.TYPE_BINARY);

        client.upload(file);


    } catch (Exception ex) {
        Logger.getLogger(ftpConnector.class.getName()).log(Level.SEVERE, null, ex);
        System.out.println(ex.toString());

    }
}

我得到这个输出：

*

java.net.SocketException: Connection reset

我很确定连接重置与我用 client.upload(file 给出的上传命令相关) ）；

我所有的变量都是在上层声明的。
