Using with the JSR310 (new api date) - LocalDate, LocalDateTime, LocalTime

Add dependence:

 
     com.fasterxml.jackson.datatype 
     jackson-datatype-jsr310 
     2.4.0 

And create a provider to register the module:

@Provider
public class JacksonConfig implements ContextResolver {
private final ObjectMapper objectMapper;

public JacksonConfig() throws Exception {

    objectMapper = new ObjectMapper()
                .disable( SerializationFeature.WRITE_DATES_AS_TIMESTAMPS )
                .disable( SerializationFeature.WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS )
                .setSerializationInclusion( JsonInclude.Include.NON_NULL )
                .registerModule( new JSR310Module() );

}

@Override
public ObjectMapper getContext( Class arg0 ) {
    return objectMapper;
} }
