// 1. 建立一個FtpClient物件
FTPClient ftpClient = new FTPClient();
try {
// 2. 建立 ftp 連線
ftpClient.connect(ip, port);
// 3. 登入 ftp 伺服器
ftpClient.login(account, passwd);

System.out.println("code : " + reply);

// 4. 讀取本地檔案
// FileInputStream inputStream = new FileInputStream(new
// File("F:\\hello.png"));
// 5. 設定上傳的路徑
ftpClient.changeWorkingDirectory(workingDir);
// 6. 修改上傳檔案的格式為二進位制
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
// 7. 伺服器儲存檔案，第一個引數是儲存在伺服器的檔名，第二個引數是檔案流
if (!ftpClient.storeFile(fileName, inputStream)) {

}
// 8. 關閉連線
inputStream.close();
ftpClient.logout();
result = true;
} catch (Exception e) {
e.printStackTrace();
} finally {
// FIXME 聽說，專案裡面最好少用try catch
// 捕獲異常，這樣會導致Spring的事務回滾出問題？？？難道之前寫的程式碼都是假程式碼！！！
if (ftpClient.isConnected()) {
try {
ftpClient.disconnect();
} catch (IOException ioe) {
}
}
}
return result;
}下面是nginx配置：
${nginx}/conf/nginx.conf中新增：
server {
listen 8088;
server_name localhost;
location / { # 存放圖片的地址
root D:/images;
index *.*;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
}
}測試nginx:命令： nginx -t
配置ftp伺服器請百度。
