如何一起使用@RequestBody和@RequestParam

Question

我尝试使用@requestbody和@requestparam通过Postman发送JSON和多个文件，但它不起作用。有可能在API中同时使用这两个注释吗？

@RequestMapping(value = "/save/product/test", method = RequestMethod.POST)
public ResponseEntity<?> save(@Valid @RequestBody ProductVo productVo, @RequestParam("files") @NotNull @NotBlank MultipartFile[] uploadfiles) {

    System.out.println("body " + productVo.toString());
    for (MultipartFile file :  uploadfiles) {
        System.out.println(file.getOriginalFilename());
        System.out.println(file.getContentType());
        System.out.println(file.getName());
        System.out.println(file.getSize());

    }
    return new ResponseEntity<APIResponse>(this.apiResponse, HttpStatus.NO_CONTENT);
}

@RequestParam从uri中获取参数，实际上是在尝试实现其他功能。

下面是一个示例控制器，使用json主体和多部分文件：

@RestController
@RequestMapping("/users")
public class UserController {

    UserService userService;

    @Autowired
    public UserController(UserService userService) {
        this.userService = userService;
    }

    @PostMapping({"/", ""})
    public ResponseEntity<User> post(@RequestPart("request") UserCreateRequest request, @RequestPart("file") MultipartFile file) throws IOException {

        String photoPath = UUID.randomUUID() + file.getOriginalFilename().replaceAll(" ", "").trim();

        // other logic

        return ResponseEntity.ok(userService.create(request));
    }
}
