表单
<html>
<head>
<title>Title</title>
</head>
<body>
<form action="/file/fileone" method="post" enctype="multipart/form-data">
<input type="file" name="file"><br>
<input type="password" name="upwd"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
控制器
@RequestMapping("/fileone") public ModelAndView fileone(HttpSession session, MultipartFile file,String upwd) throws IOException { ModelAndView mv=new ModelAndView(); System.out.println(upwd); //文件是否为空 if(!file.isEmpty()){ //获取文件名称 String filename=file.getOriginalFilename(); //获取文件上传路径 String realPath = session.getServletContext().getRealPath("/WEB-INF/file"); //创建文件对象 File file1=new File(realPath,filename); //上传文件 file.transferTo(file1); } mv.setViewName("myform"); return mv; }
多文件上传
修改控制器
@RequestMapping("/fileone1") public ModelAndView fileone1(HttpSession session, MultipartFile[] file,String upwd) throws IOException { ModelAndView mv=new ModelAndView(); System.out.println(upwd); for (MultipartFile files:file){ //是否为空 if(!files.isEmpty()){ //获取文件名称 String filename=files.getOriginalFilename(); //获取文件上传路径 String realPath = session.getServletContext().getRealPath("/WEB-INF/file"); //创建文件对象 File file1=new File(realPath,filename); //上传文件 files.transferTo(file1); } } mv.setViewName("myform"); return mv; }
修改表单
<html>
<head>
<title>Title</title>
</head>
<body>
<form action="/file/fileone" method="post" enctype="multipart/form-data">
<input type="file" name="file"><br>
