[note]Spring MultipartFile类解决文件上传问题

使用MultipartFile类解决文件的上传十分方便，代码如下：

        @RequestMapping(value = "/member/spaceBackground.do", method = RequestMethod.POST)

public void processSetupBackground(Model model, HttpServletResponse resp, HttpServletRequest req, @RequestParam("fileupload") MultipartFile fileupload) {

try {

String logoName = "logonai.gif";

String filePath = ProjectEnv.getWebappPath() + "/images/";

FileTools.input2File(filePath, fileupload.getInputStream(), logoName, true);  //将上传的文件用input流的方式传到文件logonai.gif中

PrintWriter out = resp.getWriter();

out.print("true");

out.close();

} catch (Exception e) {

e.printStackTrace();

logger.error(e.getMessage(), e);

}

}
