需要使用引擎模板thymeleaf,如果不清楚，可见04–SpringBoot之模板引擎–thymeleaf
1.新建表单网页：templates/upfile.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form enctype="multipart/form-data" method="post" action="/upload">
文件上传<input type="file" name="file"/>
<input type="submit" value="上传"/>
</form>
</body>
</html>2.控制器:toly1994.com.toly01.controller.UpFileController

@Controller
