Spring Data Elasticsearch @Field

Spring Data Elasticsearch @Field

The @Field annotation now supports nearly all of the types that can be used in Elasticsearch.

@Document(indexName = "person", type = "dummy")
public class Person implements Persistable<Long> {

    @Nullable @Id
    private Long id;

    @Nullable @Field(value = "last-name", type = FieldType.Text, fielddata = true)
    private String lastName;      (1)

    @Nullable @Field(name = "birth-date", type = FieldType.Date, format = DateFormat.basic_date)
    private LocalDate birthDate;  (2)

    @CreatedDate
    @Nullable @Field(type = FieldType.Date, format = DateFormat.basic_date_time)
    private Instant created;      (3)

    // other properties, getter, setter
}

• in Elasticsearch this field will be named last-name, this mapping is handled transparently
• a property for a date without time information
• another property this time with full date and time information
