json - Spring Boot LocalDate field serialization and deserialization

Question

In Spring Boot 1.2.3.RELEASE with fasterxml what is the correct way of serializing and de-serializing a LocalDate field to ISO date formatted string?

I've tried:

• spring.jackson.serialization.write-dates-as-timestamps:false in application.properties file,

• including jackson-datatype-jsr310 in project and then using

  • @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd") annotation

  • and @DateTimeFormat(iso=ISO.DATE) annotation,

• adding Jsr310DateTimeFormatAnnotationFormatterFactory as formatter with:

  @Override
  public void addFormatters(FormatterRegistry registry) {
      registry.addFormatterForFieldAnnotation(new Jsr310DateTimeFormatAnnotationFormatterFactory());
  }
  

None of the above helped.

Answer 1

compile ("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")

in build.gradle and then following annotations helped:

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

Update: if you are using Spring Boot 2.*, the dependency is already included via one of the "starters".
