标签:get return upload path turn 实现 byte span 文件
1.通过commons-fileupload来实现:导入jar包commons-fileupload和commons-io
2.配置springmvc:配置解析器:
"multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> "defaultEncoding" value="utf-8"/> "maxUploadSize" value="10485760000"/> "maxInMemorySize" value="40960"/>
3.编写上传处理器代码:
@RequestMapping("/upload") public String fileupload(@RequestParam("file") CommonsMultipartFile file, HttpServletRequest request) throws IOException { //获取文件名 // file.getOriginalFilename(); String path ="/fileupload"; InputStream is = file.getInputStream(); OutputStream os = new FileOutputStream(new File(path,file.getOriginalFilename())); int len=0; byte[] buffer = new byte[400]; while ((len = is.read(buffer)) != -1){ os.write(buffer,0,len); } os.close(); is.close(); return "index.jsp"; }
4.jsp页面:
