Upgrade Spring Data Elasticsearch from
3.2.4
to4.0.0
, i.e. Elasticsearch from6.8.4
to7.6.2
.Because Spring Data Elasticsearch removed Jackson
ObjectMapper
as a mapper for entity models, andMappingElasticsearchConverter
mapping operations still have issues with regards tojava.util.Date
(https://github.com/spring-projects/spring-data-elasticsearch/blob/master/src/main/java/org/springframework/data/elasticsearch/core/convert/ElasticsearchDateConverter.java#L125, cf. elastic/elasticsearch#39067), all date fields in out domain model now use the newTemporalAccessor
implementationEditDate
, so thatElasticsearchDateConverter
can work with it (https://github.com/spring-projects/spring-data-elasticsearch/blob/master/src/main/java/org/springframework/data/elasticsearch/core/convert/ElasticsearchDateConverter.java#L108).
