<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
Model class
#Document(indexName="employee", createIndex=true, shards = 4)
public class Employee {
#Nullable
#Field(type = FieldType.Date, pattern = "yyyy-MM-dd", format = DateFormat.date)
private LocalDate joinedDate;
}
ElasticSearch index properties
"mappings": {
"employee": {
"properties": {
"joinedDate": {
"format": "date",
"type": "date"
}
My Configuration file
#Configuration
#EnableElasticsearchRepositories("com.sample.dao")
public class ElasticSearchClientBuilder extends AbstractElasticsearchConfiguration{
Logger logger = LoggerFactory.getLogger(ElasticSearchClientBuilder.class);
#Override
#Bean
public RestHighLevelClient elasticsearchClient() {
//Configuration for ResthighClient
}
}
Error i am getting for above setting
Caused by: org.elasticsearch.client.ResponseException: method [PUT], host [https://ausdlcceesdb01.us.dell.com:9200], URI [/employee/employee/a77055df-2a79-4d8d-8911-315003bfed28?timeout=1m], status line [HTTP/1.1 400 Bad Request]

Without pattern in model my date is stores as below columns in index
joinedDate.year
joinedDate.month
joinedDate.dayOfMonth
joinedDate.dayOfWeek
joinedDate.era
joinedDate.dayOfYear
joinedDate.monthValue
joinedDate.chronology
joinedDate.leapYear
Please help how to store yyyy-MM-dd in index

I think you will need something like this:
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS")
#JsonSerialize(using = CustomLocalDateTimeSerializer.class)
#JsonDeserialize(using = CustomLocalDateTimeDeserializer.class)
private LocalDateTime createDate;
CustomLocalDateTimeSerializer class:
public class CustomLocalDateTimeSerializer extends StdSerializer<LocalDateTime> {
public CustomLocalDateTimeSerializer() {
this(null);
}
private CustomLocalDateTimeSerializer(Class<LocalDateTime> t) {
super(t);
}
#Override
public void serialize(LocalDateTime value, JsonGenerator gen, SerializerProvider provider) throws IOException {
gen.writeString(value.format(DateTimeFormatter.ofPattern(Constants.DATE_FORMAT_SIMPLE)));
}
}
CustomLocalDateTimeDeserializer class:
public class CustomLocalDateTimeDeserializer extends StdDeserializer<LocalDateTime> {
public CustomLocalDateTimeDeserializer() {
this(null);
}
private CustomLocalDateTimeDeserializer(Class<LocalDateTime> t) {
super(t);
}
#Override
public LocalDateTime deserialize(JsonParser jsonParser, DeserializationContext ctxt) throws IOException, JsonProcessingException {
String date = jsonParser.getText();
try {
return LocalDateTime.parse(date);
} catch (Exception ex) {
log.debug("Error while parsing date: {} ", date, ex);
throw new RuntimeException("Cannot Parse Date");
}
}
}
