yml配置
spring:
servlet:
multipart:

控制层
@Controller
@Slf4j
public class UploadController
@Value("$file.upload.path")
private String path;
@GetMapping("/")
public String uploadPage()
return "upload";
@PostMapping("/upload")
@ResponseBody
public String create(@RequestPart MultipartFile file) throws IOException
String fileName = file.getOriginalFilename();
String filePath = path + fileName;
File dest = new File(filePath);
Files.copy(file.getInputStream(), dest.toPath());
return "Upload file success : " + dest.getAbsolutePath();
前端页面
<!DOCTYPE html>
<html>
<head lang="en">
