JSP form：
选择文件:
Controller:
@RequestMapping(value="/fileUpload", method=RequestMethod.POST)
public String fileUpload(@RequestParam("file") MultipartFile file) {
// 判断文件是否为空
if (!file.isEmpty()) {
try {
// 文件保存路径
String filePath = request.getSession().getServletContext().getRealPath("/") + "upload/"
+ file.getOriginalFilename();
// 转存文件
file.transferTo(new File(filePath));
} catch (Exception e) {
e.printStackTrace();
}
}
// 重定向
return "redirect:/list.html";

将JSP代码改成如下：
