xml配置

  1. <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  2.     <property name="maxUploadSize"><value>1000000</value></property>
  3. </bean>

在这里插入图片描述

  1. @RequestMapping("upload.do")
  2.     public ModelAndView upload(MultipartFile photo) throws IllegalStateException, IOException {
  4.         String oldName = photo.getOriginalFilename();
  5.         System.out.println("oldName:"+oldName);
  6.         String suffix = oldName.substring(oldName.indexOf("."),oldName.length());
  7.         System.out.println("suffix:"+suffix);
  8.         String newName = UUID.randomUUID().toString()+suffix;
  9.         File file = new File("E:\\images\\",newName);
  10.         photo.transferTo(file);
  11.         ModelAndView mav=new ModelAndView();
  12.         mav.addObject("path","/photo/"+newName);
  13.         mav.setViewName("upload");
  14.         return mav;
  16.     }

上传页面

  1. <form action="<%=request.getContextPath() %>/upload.do" method="post" enctype="multipart/form-data">
  2. file:<input type="file" name="photo"/><br/>
  3. <input type="submit" name="add"/>
  4. </form>
  5. <img alt="" src="http://localhost:7070${path }">
