curl -XPUT -u elastic:changeme 'localhost:9200/template/people_1?pretty' -H 'Content-Type: application/json' -d'
{
"template": "people_1*", "settings": { "number_of_shards": 1, "refresh_interval": "3s" },
"mappings": {
"people_type": { "_source": { "enabled": true }, "properties": { "id": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above":256 } } }, "name": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above":256 } } }, "surname": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above":256 } } }, "username": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above":256 } } }, "age": { "type": "integer" }, "created_at": { "type": "date" } } } }, "aliases": {} } '

Elasticsearch post new document to people_1_june index

curl -XPUT -u elastic:changeme 'localhost:9200/people_1_june/people_type' -H 'Content-Type: application/json' -d' { "id": "3d7797e5-736f-441a-8a13-9a997ee71e17", "age": 27, "name": "oguzhan", "surname":"karacullu", "username":"mete00", "created_at": "2017-06-17" }
'

After creating the ES indexes and documents,
first change "application.yml" then,
gradle clean
gradle build
gradle bootRun

curl -H "Content-Type: application/json" -X POST -d '{"name": "Oguzhan","surname": "Karacullu","username": "oguz00","age": 27}' http://localhost:8080/person

Get All Person from ES index with Java Api if exist, else getter from local PostgreSql DB

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET 'http://localhost:8080/person/all'

spring-boot-kotlin-actuator
