從數據庫導出數據生成excel後放置到ftp服務器（ftp,sftp協議）

以上是創建一個名爲wb的電子excel表格
二： 下面是兩種協議的ftp服務器

String ftpUrl = StaticResource.getProMap().get("url");//ftp服務器地址
String ftpUser = StaticResource.getProMap().get("user");//ftp服務器用戶名
String ftpPass = StaticResource.getProMap().get("password");//ftp服務器密碼

1 sftp協議，默認端口22

public ChannelSftp connect(String host, int port, String username,
            String password) {
            ChannelSftp sftp = null;
            try {
            JSch jsch = new JSch();
            jsch.getSession(username, host, port);
            Session sshSession = jsch.getSession(username, host, port);
            System.out.println("Session created.");
            sshSession.setPassword(password);
            Properties sshConfig = new Properties();
            sshConfig.put("StrictHostKeyChecking", "no");
            sshSession.setConfig(sshConfig);
            sshSession.connect();
            System.out.println("Session connected.");
            System.out.println("Opening Channel.");
            Channel channel = sshSession.openChannel("sftp");
            channel.connect();
            sftp = (ChannelSftp) channel;
            System.out.println("Connected to " + host + ".");
            } catch (Exception e) {

            }
            return sftp;
            }

ChannelSftp sftp = connect(ftpUrl, 22, ftpUser, ftpPass);
ByteArrayOutputStream os = new ByteArrayOutputStream();

                try {
                 wb.write(os);
                } catch (IOException e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
                }

                byte[] b = os.toByteArray();

                ByteArrayInputStream in = new ByteArrayInputStream(b);
                sftp.cd(StaticResource.getProMap().get("doc"));//進入放置文件夾路徑下
            //boolean res = ftp.uploadFile(excel_name, in);
                try {
                    sftp.put(in, excel_name);
                    } catch (Exception e) {
                    e.printStackTrace();
                    }

2 ftp協議

FtpUtil ftp = new FtpUtil(ftpUrl, 22, ftpUser, ftpPass, "文件夾路徑");

ByteArrayOutputStream os = new ByteArrayOutputStream();

                try {
                 wb.write(os);
                } catch (IOException e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
                }

                byte[] b = os.toByteArray();

                ByteArrayInputStream in = new ByteArrayInputStream(b);
boolean res = ftp.uploadFile(excel_name , in);
