elasticSearch使用LocaldateTime

elasticSearch版本6.8.12 springboot版本2.2.7 springdataelasticSearch版本3.2.7

使用 

ElasticsearchRepository  向elasticSearch 中添加 時間類型為LocaldateTime 的記錄

        }

        @Override

            } catch (IOException e) {
                throw new MappingException(e.getMessage(), e);
            }
        }

        @Override

            try {
                return mapToObject(mapToString(source), targetType);
            } catch (IOException e) {
                throw new MappingException(e.getMessage(), e);
            }
        }
    }
}

如果沒有這個配置類  LocaldateTime 會被轉成

一個類似下面的json 串 而elasticSearch 序列化不了這個json

"creationDate": {
    "dayOfYear": 123,
    "dayOfWeek": "FRIDAY",
    "month": "MAY",
    "dayOfMonth": 3,
    "year": 2019,
    "monthValue": 5,
    "hour": 11,
    "minute": 54,
    "second": 12,
    "nano": 238000000,
    "chronology": {
        "id": "ISO",
        "calendarType": "iso8601"
    }
},

所以需要自定義entityMapper的對象使用jackson 來轉化 對應的localdateTIme來實現
