Java Spring Boot 文件上传控制器路径注意

@Slf4j
@RestController
public class UploadController {
    @PostMapping("/upload")
    public Result upload(String name, Integer age, MultipartFile file) throws IOException {
        log.info("接收参数：{} {} {}", name, age, file);
        String originalFilename = file.getOriginalFilename();
        file.transferTo(new File("C:/Users/Adventure/Desktop/Tmp/" + originalFilename));
        return Result.success();
    }
}

"C:/Users/Adventure/Desktop/Tmp/" 路径后面记得加/，不然就是Tmp{originalFilename}了
