Controller层代码：

@Controller @RequestMapping("/hdfs") public class hdfsController {private hdfsService hdfsService; public hdfsService getHdfsService() { return hdfsService; } @Resource public void setHdfsService(hdfsService hdfsService) { this.hdfsService = hdfsService; }@RequestMapping("/delete") public String toDelete(@RequestParam(value="https://www.it610.com/article/path",required=false) String path) throws IOException{ hdfsService.delete(path); return "success"; }@RequestMapping(value="https://www.it610.com/ls",method=RequestMethod.GET) public ModelAndView home(@RequestParam(value="https://www.it610.com/article/path",required=false) String path, HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView model = new ModelAndView(); if (StringUtils.isEmpty(path)) { path = "/"; } List hdfsFiles =hdfsService.ls(path); model.addObject("file", hdfsFiles); model.setViewName("/ls"); return model; }@RequestMapping("/download") public String toDownload(@RequestParam(value="https://www.it610.com/article/path",required=false) String path) throws IOException{ hdfsService.download(path); return "success"; }@RequestMapping(value="https://www.it610.com/upload") public String upLoad(HttpServletRequest request, HttpServletResponse response) throws IllegalStateException, IOException{ //解析器解析request的上下文 CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext()); //先判断request中是否包涵multipart类型的数据， if(multipartResolver.isMultipart(request)) { //再将request中的数据转化成multipart类型的数据 MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request; Iterator iter = multiRequest.getFileNames(); while(iter.hasNext()) { MultipartFile file = multiRequest.getFile(iter.next()); if(file != null) { String FileName = file.getOriginalFilename(); System.out.println(FileName); CommonsMultipartFile cf= (CommonsMultipartFile)file; DiskFileItem fi = (DiskFileItem)cf.getFileItem(); File inputFile = fi.getStoreLocation(); hdfsService.createFile(inputFile, "hdfs://192.168.88.100:8020/upload/"+FileName); } } } return "success"; }

前端部分页面：

HDFS文件管理器 - 锐客网文件名文件大小拥有者权限时间操作 ${file.fileName} ${file.fileSize} ${file.owner} ${file.permission} ${file.modificationTime} 删除下载
