幾個步驟說明:
ftpClient.setRemoteVerificationEnabled(false); ftpClient.setControlEncoding("utf-8"); ftpClient.connect(ftpConfig.getHostname(), ftpConfig.getPort()); //連接ftp服務器 ftpClient.login(ftpConfig.getUsername(), ftpConfig.getPassword()); //登錄ftp服務器 int replyCode = ftpClient.getReplyCode(); //是否成功登錄服務器 if(!FTPReply.isPositiveCompletion(replyCode)){ logger.warn("【initFtpClient】: 登錄服務器失敗"); logger.warn("【initFtpClient】: connect failed...ftp服務器:"); } ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE); //設置文件類型:文件類型為二進制文件 ftpClient.setControlEncoding("GBK"); //設置編碼為GBK CreateDirecroty(pathname); ftpClient.makeDirectory(pathname); //設置目錄 ftpClient.changeWorkingDirectory(pathname); //設置工作路徑 ftpClient.enterLocalPassiveMode(); //設置被動模式 ftpClient.storeFile(fileName, inputStream);//上傳 inputStream.close(); ftpClient.logout(); ftpClient.disconnect();
