前端代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>upload</title> </head> <body> <form action="http://localhost:8080/api/upload" enctype="multipart/form-data" method="post"> <input id="file" type="file" name="files" multiple webkitdirectory /> <input type="submit" value="上传文件夹" /> </form> </body> </html>
后端代码：
@RequestMapping("/api/upload")
public class UploadController {
@PostMapping
public ResponseData<?> folder(MultipartFile[] files) throws IOException {
for (MultipartFile file : files) {
//上传文件目录
String uploadFolder = "D:/upload_test";
String fileName = file.getOriginalFilename();
File uploadFile = new File(uploadFolder,fileName);
//判断上传文件目录是否存在，如果不存在就创建
if (!uploadFile.getParentFile().exists()) {
uploadFile.getParentFile().mkdirs();
}
file.transferTo(uploadFile);
}
return new ResponseData<>().success();
}
}
是不是觉得很简单哉，那就赶快自己动手试一试吧！
