创建ftp服务器

1.创建ftp角色

2.打开windows的ftp服务器功能

登录成功,访问到d盘  /mulu/file/

开启ftp角色对于目录的读写权限 (先添加角色进去,再开启读写权限)

自己配置nginx 映射 d://mulu/file

Java实现ftp上传功能

ftp上传工具类

工具类 配置参数 ,账号,密码,端口 ,ip 上传文件夹

#ftp相关  这里的ip是ftp服务器ip, 我是在已有服务器172.16.1.13上测试的,不是在刚设置的172.16.1.20上测试的,填写自己的ftp服务器IP即可
    ftp.account=zhylftp
    ftp.password=zhylftp
    ftp.port=21
    ftp.server=172.16.1.13
    ftp.fileFolder=/provide

ftp上传包装方法

@Value("${ftp.head.url}")
        private String ftpUrl;
    
    //ftp文件上传
        @Override
        public ResultVO ftpUpload(MultipartFile file, QueryParam param) {
            try {
                // 获取旧文件名
                String fileName = file.getOriginalFilename();
                if (StringUtils.isEmpty(fileName)) {
                    throw new GlobalException("文件名有误");
                }
                log.info("上传的文件名为：" + fileName);
                // 获取文件的后缀名
                String suffixName = fileName.substring(fileName.lastIndexOf("."));
                log.info("上传的后缀名为：" + suffixName);
    
                log.info("ftp文件上传  ftpUtil ======{}", JSON.toJSONString(ftpUtil));
                InputStream inputStream = file.getInputStream();
                String UUIDName = UUID.randomUUID().toString().replace("-", "") + suffixName; //新文件名
                log.info("上传的文件名为：" + (UUIDName));
                boolean b = ftpUtil.uploadFile(ftpUtil.fileFolder, UUIDName, inputStream);
                if(b){
                    String fileUrl = ftpUrl+ftpUtil.fileFolder+"/"+UUIDName;
                    Map map = new HashMap();
                    map.put("oldFileName", fileName);
                    map.put("picName", UUIDName);
                    map.put("url", fileUrl);
                    return new ResultVO(StatusCode.RESULT_SUCCESS,map);
                }else {
                    return new ResultVO(StatusCode.UPLOAD_FILE_ERROR);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return new ResultVO(StatusCode.SYSTEM_EXCEPTION);
        }

ftpUrl 访问头

#ftp 上传访问头
    ftp.head.url=http://172.16.1.13:8999
