SpringBoot项目上传图片到FTP服务器

1. properties配置

#ftp
ftp.url&＃61;192.168.101.1 ftp路径
ftp.host&＃61;21 ftp端口号
ftp.user&＃61;ftpadmin 用户名
ftp.password&＃61;123456 密码
ftppath:/ftpFile 上传的路径


2. ftp上传工具类

* Description: 向FTP服务器上传文件* &＃64;param ftpHost FTP服务器hostname* &＃64;param ftpUserName 账号* &＃64;param ftpPassword 密码* &＃64;param ftpPort 端口* &＃64;param fileName ftp文件名称* &＃64;param input 文件流* &＃64;return 成功返回true&＃xff0c;否则返回false*/public static boolean uploadFile(String ftpHost, String ftpUserName,String ftpPassword, int ftpPort,String fileName,InputStream input) {boolean success &＃61; false;FTPClient ftpClient &＃61; null;try {int reply;ftpClient &＃61; getFTPClient(ftpHost, ftpUserName, ftpPassword, ftpPort);reply &＃61; ftpClient.getReplyCode();if (!FTPReply.isPositiveCompletion(reply)) {ftpClient.disconnect();return success;}ftpClient.setControlEncoding("UTF-8"); // 中文支持ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);ftpClient.enterLocalPassiveMode();//ftpClient.changeWorkingDirectory(ftpPath);//设置编码&＃xff0c;防止上传的时候使用postman上传成功&＃xff0c;但是前端上传失败&＃xff08;编码的格式&＃xff09;ftpClient.storeFile(new String(fileName.getBytes("gbk"), "iso-8859-1"), input);input.close();ftpClient.logout();success &＃61; true;} catch (IOException e) {e.printStackTrace();} finally {if (ftpClient.isConnected()) {try {ftpClient.disconnect();} catch (IOException ioe) {}}}return success;}


3. 一个简单的Controller

&＃64;Value("${ftp.url}")private String server;&＃64;Value("${ftp.host}")private int port;&＃64;Value("${ftp.user}")private String userName;&＃64;Value("${ftp.password}")private String userPassword;&＃64;Value("${ftppath}")private String ftppath;/***上传图片到ftp* &＃64;return* &＃64;throws Exception*/&＃64;RequestMapping(value &＃61; "saveUploadFile",method &＃61; RequestMethod.POST)&＃64;ResponseBodypublic ReturnResult saveUploadFile(&＃64;RequestBody MultipartFile file, HttpServletRequest request) throws Exception{try {String fileName &＃61; file.getOriginalFilename();String name &＃61; request.getParameter("river");FtpUtils ftp &＃61; new FtpUtils(server,port,userName,userPassword);if(name!&＃61;null){videoService.updateGgp(name,fileName);if (ftp.open()) {ftp.uploadFile(server, userName,userPassword, port,fileName,file.getInputStream());}if (fileName &＃61;&＃61; null){Map map &＃61; new HashMap<>();map.put("上传失败",fileName);}}Map map &＃61; new HashMap<>();map.put("name",fileName);return new ReturnResult(Constant.ResultCode.SUCCESS, "请求成功", map);} catch (Exception e) {e.printStackTrace();return new ReturnResult(Constant.ResultCode.ERROR, "请求失败");}}


postman测试成功上传图片到FTP服务器&＃xff0c;同时数据库的图片路径也修改为上传的这个图片的路径
