这是我的控制器：

@RestController
@RequestMapping("/api/product")
public class ProductController {

    @Autowired
    ProductService productService;
    
    @PreAuthorize(value = "hasRole('ADD_PRODUCT')")
    @PostMapping(value = "/add", consumes = {
            MediaType.MULTIPART_FORM_DATA_VALUE,
            MediaType.APPLICATION_JSON_VALUE
    })
    public HttpEntity<?> addProduct(@CurrentUser User user,
                                    @RequestPart("files") MultipartFile multipartFile,
                                    @Valid @RequestPart("info") ProductDto productDto) {
        ApiResponse apiResponse = productService.addProduct(user, productDto, multipartFile);
        return ResponseEntity.status(apiResponse.isSuccess() ? 201 : 409).body(apiResponse);
    }

}

它应该接收一个MultipartFile和Json对象，我的ProductDto类是：

@Data
@AllArgsConstructor
@NoArgsConstructor
public class ProductDto {

    @NotNull(message = "Name can't be empty")
    @NotBlank(message = "Name can't be blank")
    private String name;
    
    @Length(max = 1000)
    private String description;
    
    
    @NotNull(message = "Price can't be empty")
    private double price;//Evaluated in the $
    
    @NotNull(message = "You should choose one of the categories")
    private UUID categoryId;

}

尝试发送请求

时遇到困难
但它总是给我403禁止，我不知道原因，这个请求根本没有来到addProduct（）方法，我有权限"ADD_PRODUCT"。@CurrentUser注解类是

@Documented
@Retention(value = RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER) 
@AuthenticationPrincipal
public @interface CurrentUser { }

也不会引发任何错误或异常
我已经尝试了@RequestParam和@RequestPart这两个注解，我想学习如何在同时发送MultipartFile和Json对象时处理此类情况。
