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
public class UpFileController {
@GetMapping("/upload_html")
public String uploadHtml() {
return "upfile";
}
//处理文件上传
@PostMapping(value = "/upload")
public @ResponseBody
String uploadImg(
@RequestParam("file") MultipartFile file, HttpServletRequest request) {
if (file.isEmpty()) {
return "false";
}
String fileName = file.getOriginalFilename();//获取名字
String path = "F:/test";
File dest = new File(path + "/" + fileName);
if (!dest.getParentFile().exists()) { //判断文件父目录是否存在
dest.getParentFile().mkdir();
}
try {
file.transferTo(dest); //保存文件
return "上传成功!";
} catch (IllegalStateException | IOException e) {
e.printStackTrace();
return "上传失败!";
}
}
}
