Java 8 LocalDate Jackson format

Question

For java.util.Date when I do

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = \"dd/MM/yyyy\")  
  private Date dateOfBirth;
<         


        

Answer 1

If your request contains an object like this:

{
    "year": 1900,
    "month": 1,
    "day": 20
}

Then you can use:

data class DateObject(
    val day: Int,
    val month: Int,
    val year: Int
)
class LocalDateConverter : StdConverter() {
    override fun convert(value: DateObject): LocalDate {
        return value.run { LocalDate.of(year, month, day) }
    }
}

Above the field:

@JsonDeserialize(converter = LocalDateConverter::class)
val dateOfBirth: LocalDate

The code is in Kotlin but this would work for Java too of course.
