下载：
1.在spring-mvc中配置(用于100M以下的文件下载)
<bean> <property name="messageConverters"> <list> <> <bean/> <bean> <> <property name="supportedMediaTypes" value="application/json; charset=UTF-8" /> </bean> </list> </property> </bean>
下载文件代码
@RequestMapping("/file/{name.rp}") public ResponseEntity<byte[]> fileDownLoad(@PathVariable("name.rp")String name, HttpServletRequest request,HttpServletResponse response) { // @PathVariable String name, // @RequestParam("name")String name, // System.out.println("<name>"+name); // System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"); ResponseEntity<byte[]> re = null; try { /** * css,js,json,gif,png,bmp,jpg,ico,doc,docx,xls,xlsx,txt,swf,pdf * **/ //下载防止静态加载干扰 Feelutile f=new Feelutile(); name=f.getfileformat(name); String pathString="C:tempDirectory"+name; File file=new File(pathString); HttpHeaders headers=new HttpHeaders(); //String filename=URLEncoder.encode(name, "UTF-8");//为了解决中文名称乱码问题 String filename=new String(name.getBytes("utf-8"),"utf-8"); byte[] by=FileUtils.readFileToByteArray(file); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); //URLEncoder.encode(filename, "UTF-8") headers.setContentDispositionFormData("attachment",filename); headers.setContentLength(by.length); re=new ResponseEntity<byte[]>(by, headers, HttpStatus.CREATED); } catch (Exception e) { e.printStackTrace(); try { request.getRequestDispatcher("/error/404.jsp").forward(request, response); } catch (ServletException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } return re; }
上传文件:
1在spring-mvc中配置
<> <bean id="multipartResolver" > <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <value>1048576000</value> </property> <property name="maxInMemorySize"> <value>40960</value> </property> </bean>
在controller中代码如下
@RequestMapping(value="/upload", method = RequestMethod.POST) @ResponseBody public Json upload(Doc doc, @RequestParam("uploadFile") CommonsMultipartFile file) { Json j = new Json(); try { String realpath = this.servletContext.getRealPath("/upload"); String uploadFileFileName = file.getOriginalFilename(); String uploadFileFileNameWithoutSpace = uploadFileFileName.replaceAll(" ", ""); String fileType = uploadFileFileNameWithoutSpace.substring(uploadFileFileNameWithoutSpace.lastIndexOf(".")); File targetFile = new File(realpath+File.separator, uploadFileFileNameWithoutSpace); if (targetFile.exists()) { targetFile.delete(); } file.getFileItem().write(targetFile); docService.upload(doc,uploadFileFileNameWithoutSpace); j.setSuccess(true); j.setMsg("Upload manual successfully"); }catch (Exception e) { logger.error(ExceptionUtil.getExceptionMessage(e)); j.setMsg("Upload manual unsuccessfully"); } return j; }
