I am working on custom `JSON` deserialiser and have the below class

```
public class yyyy_MM_dd_DateDeserializer extends StdDeserializer <LocalDate> {

 public yyyy_MM_dd_DateDeserializer() {
  this(null);
 }

 public yyyy_MM_dd_DateDeserializer(Class t) {
  super(t);
 }

 @Override
 public LocalDate deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
  String dateString = jsonParser.getText();
  LocalDate localDate = null;
  try {
   localDate = LocalDate.parse(dateString, "yyyy-MM-dd");
  } catch (DateTimeParseException ex) {
   throw new RuntimeException("Unparsable date: " + dateString);
  }
  return localDate;
 }
}

```

and in my request class

```
@Valid
@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
private LocalDate endDate;

```

It works fine but I am wondering if I can pass the date format dynamically. Instead of hardcoding in `yyyy_MM_dd_DateDeserializer`.
I want to pass the date format from my request class so that my deserialiser is more generic any anyone can use it by sending the required format.
