这个问题困扰了我一个星期,

我正在尝试使用 java 上传带有 ftp 的文件 xml,没什么太花哨的。

经过一些网络搜索后,我决定使用 ftp4j 包,根据文档应该可以解决问题。

关键是这个 ftp 服务器实际上与 Filezilla 一起工作......

这些是我的代码的几行:

    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());

    }
}

好吧,我得到了这个输出:

java.net.SocketException: Connection reset

我很确定连接重置与我使用 client.upload(file); 提供的上传命令有关。

我所有的变量都在上层声明。
