springboot以FTP方式上传文件到远程服务器
一、html代码
<div class="layui-form-item"> <label class="layui-form-label">上传附件:</label> <div class="layui-input-block doc-litpic"> <button type="button" name="avatar" class="layui-btn layui-btn-sm" data-url="/admin/archives/upload.html" id="larry-litpic"><i class="layui-icon"></i>本地上传</button> <a id="upload-filename-display" style="color: blue" href=""></a> <div class="larryms-img-view"> </div> </div> </div>
二、js代码
upload.render({ accept: 'file', elem: '#larry-litpic', url: interface_cms_article_upload, field: 'fileNames', done : function (res, index, upload) { if(res.code != 200){ layer.open({ icon : 2, skin : "layui-layer-molv", content : res.msg }); }else{ layer.open({ icon : 1, skin : "layui-layer-molv", content : res.msg }); $('#upload-filename-display').text(res.filename); $("input[name='fileId']").val(res.filename); } }, error : function (res) { } });
三、后台controller:
@RequestMapping(value = "/upload") @ApiOperation(value = "本地文件上传",notes ="本地文件上传" ) public Map uploadfunction(HttpServletRequest request, HttpServletResponse response){ //创建文件对象并获取请求中的文件对象 MultipartFile file = null; Map resultData = new HashMap(); try{ MultipartHttpServletRequest mRequest = (MultipartHttpServletRequest) request; file = mRequest.getFile("fileNames"); //判断上传非空 if(null == file) { resultData.put("code",0); resultData.put("msg","上传文件失败"); resultData.put("filename",file.getOriginalFilename()); return resultData; } //上传需要导入数据的文件 //用来检测程序运行时间 long startTime=System.currentTimeMillis(); System.out.println("上传的文件名为:"+file.getOriginalFilename()); String fileName = file.getOriginalFilename(); InputStream inputStream = file.getInputStream(); String hostName = uploadUtil.getHostname(); String username = uploadUtil.getUsername(); String password = uploadUtil.getPassword(); String targetPath = uploadUtil.getTargetPath(); String suffix = cmsArticleService.getSuffix(fileName); fileName = cmsArticleService.upload(hostName,username,password,targetPath,suffix,inputStream); //计算上传时间 long endTime=System.currentTimeMillis(); String uploadTime = String.valueOf(endTime-startTime); System.out.println("上传所用时间:"+uploadTime+"ms"); resultData.put("code",200); resultData.put("msg","上传文件成功"); resultData.put("filename",fileName); return resultData; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; }
四、后台service上传至远程服务器
//FTP文件上传 public static String upload(String hostname,String username,String password, String targetPath,String suffix,InputStream inputStream) throws SocketException, IOException { //实例化ftpClient FTPClient ftpClient = new FTPClient(); //设置登陆超时时间,默认是20s ftpClient.setDataTimeout(12000); //1.连接服务器 ftpClient.connect(hostname,21); //2.登录(指定用户名和密码) boolean b = ftpClient.login(username,password); if(!b) { System.out.println("登陸超時"); if (ftpClient.isConnected()) { // 断开连接 ftpClient.disconnect(); } } // 设置字符编码 ftpClient.setControlEncoding("UTF-8"); //基本路径,一定存在 String basePath="/"; String[] pathArray = targetPath.split("/"); for(String path:pathArray){ basePath+=path+"/"; //3.指定目录 返回布尔类型 true表示该目录存在 boolean dirExsists = ftpClient.changeWorkingDirectory(basePath); //4.如果指定的目录不存在,则创建目录 if(!dirExsists){ //此方式,每次,只能创建一级目录 boolean flag=ftpClient.makeDirectory(basePath); if (flag){ System.out.println("创建成功!"); } } } //重新指定上传文件的路径 ftpClient.changeWorkingDirectory(targetPath); //5.设置上传文件的方式 ftpClient.setFileType(FTP.BINARY_FILE_TYPE); //使用uuid,保存文件名唯一性 String uuid= UUID.randomUUID().toString(); /** * 6.执行上传 * remote 上传服务后,文件的名称 * local 文件输入流 * 上传文件时,如果已经存在同名文件,会被覆盖 */ boolean uploadFlag = ftpClient.storeFile(uuid+suffix,inputStream); if(uploadFlag) System.out.println("上传成功!"); return uuid+suffix; }
五、获取yml配置的工具类
@Data @Component public class UploadUtil { @Value("${upload.hostname}") private String hostname; @Value("${upload.username}") private String username; @Value("${upload.password}") private String password; @Value("${upload.targetPath}") private String targetPath; }
