更新映像时在springboot mongo中出现错误，一切似乎都很好

如何解决更新映像时在springboot mongo中出现错误，一切似乎都很好

向我的服务提交数据时，出现以下错误：

已解决[org.springframework.web.multipart.support.MissingServletRequestPartException：所需的请求部分'实体'不存在”错误，并且不知道我错过了什么建议会有所帮助

不知道使用类似的api是什么问题

@CrossOrigin(origins = "*",maxAge = 3600)
@RestController
@RequestMapping("/api/entity")
public class EntityController {

    @Autowired
    IEntityRepository entityRepository;
@RequestMapping(value = "/updateEntity",method = RequestMethod.POST,consumes = "multipart/form-data")
        public ResponseEntity<Entity> updateEntity(@RequestPart("entity") @Valid Entity entity,@RequestPart("file") @Valid Optional<MultipartFile> image) throws IOException {
    
    // routine to update a entity including image
            byte[] imageData = null;
            if (image.isPresent() && image.get() != null)
                imageData = image.get().getBytes();
            if (imageData == null && entity.getId() != null) {
                Optional<Entity> readEntity = entityRepository.findById(entity.getId());
                if (readEntity.get() != null)
                    imageData = readEntity.get().getImage().getData();
            }
            if (imageData != null) {
                entity.setImage(new Binary(BsonBinarySubType.BINARY,imageData));
            }
            Entity result = entityRepository.save(entity);
            return ResponseEntity.ok().body(result);
    
        }

Models (did not add constructor or getters and setters)
public class Entity {

    @Id
    private String id;

    private Types types;
    private String username;
    private String name;
    private String surname;
    private Binary image;
    private String address;
    private String email;
    private String contactNo;
    private String country;
    private Status status;
    private List<UserRolls> userRolls;
    private MemberShip memberShip;
    private Staff staff;

    private Payee payee;

    private List<BankAccount> userBankAccount;
    private String loginCode;
    @NotBlank
    @Size(max = 120)
    private String password;

React snippet using values from formik and getting the binairy data from the image im selecting,dont suspect it to be the image
    

    async function submitForm(values) {
/* routine to send the request to the server/*
            const formData = new FormData();
            var postData = values;
            formData.append(
                'bank',new Blob([JSON.stringify(postData)],{
                    type: 'application/json',})
            );
    
            if (imageData) {
                formData.append('file',imageData);
            }
    
            //Send Api request
            return Api(`auth/updateUser`,'Post',formData);
        }

解决方法

问题在前端出现了拼写错误，我提交并附加银行应更改为实体
