Format Date with OpenFeign - spring-boot

Question

My Feign client is defined as follow :
#FeignClient(name = "${feign.name}",url = "${feign.url}",
configuration = {DateFormatConfiguration.class})
public interface MyFeignClient {
#GetMapping(value = "/test")
ResponseEntity<MyResponse> getResponse(#RequestParam(value = "date") Date date);
}
Where :
class DateFormatConfiguration {
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
#Bean
public FeignFormatterRegistrar dateFeignFormatterRegistrar() {
return formatterRegistry -> formatterRegistry.addFormatter(new Formatter<Date>() {
#Override
public Date parse(String text, Locale locale) throws ParseException {
return df.parse(text);
}
#Override
public String print(Date object, Locale locale) {
return df.format(object);
}
});
}
}
However when I run this test :
#Test
public void test(){
Date date= new GregorianCalendar(2000, 12, 31).getTime();
myFeignClient.getResponse(date);
}
the request is sent into this format :
---> GET https:xxx/test?date=Wed%20Jan%2031%2000%3A00%3A00%20EST%202001
What I'm trying to have is :
---> GET https:xxx/test?date=2000-12-31
Where the date is formatter as I need.
I've tried also this solution, but not working neither:
class DateFormatConfiguration {
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
#Bean
public JacksonEncoder feignEncoder() {
return new JacksonEncoder(customObjectMapper());
}
#Bean
public JacksonDecoder feignDecoder() {
return new JacksonDecoder(customObjectMapper());
}
private ObjectMapper customObjectMapper(){
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setDateFormat(df);
return objectMapper;
}
}
Any Ideas ?

You should consider trying replace necessary lines with something like this:
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd");
LocalDate date= LocalDate.ofInstant(new GregorianCalendar(2000, 12, 31).getTime().toInstant(), ZoneId.of(TimeZone.getDefault().getID()));
String dateFormatted = date.format(dtf);
