import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;

@Controller
@RequestMapping("user")

	 * @throws Exception
	 */
	@RequestMapping("/fileupload2")
	public String fileupload2(HttpServletRequest request, MultipartFile upload) throws Exception {
		System.out.println("springmvc文件上传...");
		// 上传的位置
		String path = request.getSession().getServletContext().getRealPath("/uploads/");
		// 判断该路径是否存在
		File file = new File(path);
		if (!file.exists()) {
			file.mkdirs();
		}

		// 上传文件项
		String filename = upload.getOriginalFilename();
		String uuid = UUID.randomUUID().toString().replace("-", "");
		String saveName = uuid + "_" + filename.substring(filename.lastIndexOf(File.separator) + 1);
		upload.transferTo(new File(path, saveName));

		return "success";
	}
}
