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

@JsonSerialize and @JsonDeserialize worked fine for me. They eliminate the need to import the additional jsr310 module:

@JsonDeserialize(using = LocalDateDeserializer.class)  
@JsonSerialize(using = LocalDateSerializer.class)  
private LocalDate dateOfBirth;

Deserializer:

public class LocalDateDeserializer extends StdDeserializer {

    private static final long serialVersionUID = 1L;

    protected LocalDateDeserializer() {
        super(LocalDate.class);
    }


    @Override
    public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt)
            throws IOException, JsonProcessingException {
        return LocalDate.parse(jp.readValueAs(String.class));
    }

}

Serializer:

public class LocalDateSerializer extends StdSerializer {

    private static final long serialVersionUID = 1L;

    public LocalDateSerializer(){
        super(LocalDate.class);
    }

    @Override
    public void serialize(LocalDate value, JsonGenerator gen, SerializerProvider sp) throws IOException, JsonProcessingException {
        gen.writeString(value.format(DateTimeFormatter.ISO_LOCAL_DATE));
    }
}
