SpringMVC配置

<!-- 文件上传 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"></bean>

Controller得到MultipartFile

@RequestMapping("/upload")public String upload( @RequestParam("file") MultipartFile multifile){ // 创建目录  <span style="white-space:pre"></span>try {cnmlService.persisted(multifile);} catch (Exception e) {}return "suc";}
