Spring Cloud Openfeign Extra double quote added for LocaleDateTime when send request as multipart/form-data

Feign config

    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;

    @Bean
    public Encoder feignFormEncoder() {
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
    }

Client

@PostMapping("/send")
@Headers("Content-Type: multipart/form-data")
void send (@ModelArttibute SendRequest request);

Request

public class SendRequest {

  @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
  private LocalDateTime time;

  // Setter And Getter....
}

If I send the request out with Feign, I can see my request will have extra double quote for the time value.

-----------------------------9051914041544843365972754266
Content-Disposition: form-data; name="file1"; filename="a.txt"
Content-Type: text/plain

"2022-12-14 11:47:20"

The request should be like as below

-----------------------------9051914041544843365972754266
Content-Disposition: form-data; name="file1"; filename="a.txt"
Content-Type: text/plain

2022-12-14 11:47:20

How can I solve it? And what is the reason?

Hello @asdeq20062, please provide a minimal, complete, verifiable example that reproduces the issue as a link to a repo with a small executable app rather than separate code snippets - we'll take a look at it then.
