JSON Question

Java 8 LocalDate Jackson format

For java.util.Date when i do

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

then in json request when i send

{ {"dateOfBirth":"01/01/2000"} }

it works.

How should i do this for Java 8's LocalDate field??

I tried having

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

It didn't work.

Can someone please let me know what's the right way to do this..

Below are dependencies


Answer Source

I was never able to get this to work simple using annotations. To get it to work, I created a ContextResolver for ObjectMapper, then I added the JSR310Module, along with one more caveat, which was the need to set write-date-as-timestamp to false. See more at the documentation for the JSR310 module. Here's an example of what I used.



Note: One problem I faced with this is that the jackson-annotation version pulled in by another dependency, used version 2.3.2, which cancelled out the 2.4 required by the jsr310. What happened was I got a NoClassDefFound for ObjectIdResolver, which is a 2.4 class. So I just needed to line up the included dependency versions


import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JSR310Module;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

public class ObjectMapperContextResolver implements ContextResolver<ObjectMapper> {  
    private final ObjectMapper MAPPER;

    public ObjectMapperContextResolver() {
        MAPPER = new ObjectMapper();
        MAPPER.registerModule(new JSR310Module());
        MAPPER.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

    public ObjectMapper getContext(Class<?> type) {
        return MAPPER;

Resource class

public class LocalDateResource {

    public Response getPerson() {
        Person person = new Person();
        person.birthDate = LocalDate.now();
        return Response.ok(person).build();

    public Response createPerson(Person person) {
        return Response.ok(

    public static class Person {
        public LocalDate birthDate;


curl -v http://localhost:8080/api/person
Result: {"birthDate":"2015-03-01"}

curl -v -POST -H "Content-Type:application/json" -d "{\"birthDate\":\"2015-03-01\"}" http://localhost:8080/api/person
Result: 2015-03-01
