How to customize the date type serializer

@PostMapping(value = "uri", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String request(@RequestBody DataForm form);

@Data
public class DataForm implements Serializable {
    /**
     * start time eg: 2018-01-01 06:00:00
     */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime sd;
    /**
     * end time eg: 2018-01-01 21:00:00
     */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime ed;
}

---> POST https://httpreq.com/small-block-yri972hg/record/ HTTP/1.1
Content-Length: 113
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
ed=2022-01-30T00%3A00&sd=2021-12-01T00%3A00
---> END HTTP (113-byte body)

Interfacing with third-party websites, the request body type cannot be changed

The above request will be executed to feign.form.UrlencodedFormContentProcessor#encode here to process POJO field value,
If the field value is of Date/LocalDate/LocalDateTime type, the expected value cannot be obtained,
I want a custom date type serializer.

I want to customize this UrlencodedFormContentProcessor object to support serialized date objects, how to do it
