利用SpringMVC上传文件，也可以一次上传多个文件。
上传多个文件的时候用MultipartFile[] file即可
页面表单
<html>
<head>
<title>Upload a file please</title>
</head>
<body>
<h1>Please upload a file</h1>
<form method="post" action="/form" enctype="multipart/form-data">
<input type="text" name="name"/>
<input type="file" name="file"/>
<input type="submit"/>
</form>
</body>
</html>
控制层JAVA代码
@Controller
public class FileUploadController {
@RequestMapping(value = "/form", method = RequestMethod.POST)
public String handleFormUpload(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file) {
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:uploadSuccess";
} else {
return "redirect:uploadFailure";
}
}
}
