FTPClient ftpClient = new FTPClient();

ftpClient.login("username", "password");

int replyCode = ftpClient.getReplyCode();
if (!FTPReply.isPositiveCompletion(replyCode)) {
    System.out.println("登录失败，请检查用户名和密码。");
    ftpClient.disconnect();
    return;
}

ftpClient.setFileType(FTP.BINARY_FILE_TYPE);

File imageFile = new File("path/to/image.jpg");
FileInputStream inputStream = new FileInputStream(imageFile);
boolean success = ftpClient.storeFile("/remote/path/image.jpg", inputStream);
inputStream.close();
if (success) {
    System.out.println("图像上传成功。");
} else {
    System.out.println("图像上传失败。");

ftpClient.logout();
ftpClient.disconnect();
