java - Elastic 2.3.1 で日付のインデックスを作成できない

Question

私のマッピング:

{
    "field": {
        "dynamic_templates": [{
            "notanalyzed": {
                "match": "*",
                "match_mapping_type": "string",
                "mapping": {
                    "type": "string",
                    "index": "not_analyzed"
                }
            }
        }],
        "properties": {
            "createdOn": {
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss"
            },
            "lastUpdatedOn": {
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss"
            }
        }
    }
}

私のクラス:

package be.smartask.core.api.data;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author Glenn Van Schil
 *         Created on 19/04/2016
 */
public class AbstractData {
    private final static SimpleDateFormat SIMPLE_DATE_FORMAT = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private String id;
    private String createdOn;
    private String lastUpdatedOn;

    public AbstractData() {
    }

    public AbstractData(Date createdOn, String id, Date lastUpdatedOn) {
        this.createdOn = SIMPLE_DATE_FORMAT.format(createdOn);
        this.id = id;
        this.lastUpdatedOn = SIMPLE_DATE_FORMAT.format(lastUpdatedOn);
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public Date getCreatedOn() {
        try {
            return SIMPLE_DATE_FORMAT.parse(createdOn);
        } catch (ParseException e) {
            return null;
        }
    }

    public void setCreatedOn(Date createdOn) {
        this.createdOn = SIMPLE_DATE_FORMAT.format(createdOn);
    }

    public Date getLastUpdatedOn() {
        try {
            return SIMPLE_DATE_FORMAT.parse(lastUpdatedOn);
        } catch (ParseException e) {
            return null;
        }
    }

    public void setLastUpdatedOn(Date lastUpdatedOn) {
        this.lastUpdatedOn = SIMPLE_DATE_FORMAT.format(lastUpdatedOn);
    }
}

と

package be.smartask.data;

import be.smartask.core.api.data.AbstractData;

import java.util.Date;

/**
 * @author Glenn Van Schil
 *         Created on 25/01/2016
 */
public class Field extends AbstractData {

    private String name;
    private FieldType fieldType;
    private String unit;
    private String userId;
    private String projectId;

    public Field() {
    }

    public Field(Date createdOn, String id, Date lastUpdatedOn, FieldType fieldType, String name, String projectId, String unit, String userId) {
        super(createdOn, id, lastUpdatedOn);
        this.fieldType = fieldType;
        this.name = name;
        this.projectId = projectId;
        this.unit = unit;
        this.userId = userId;
    }

    public FieldType getFieldType() {
        return fieldType;
    }

    public void setFieldType(FieldType fieldType) {
        this.fieldType = fieldType;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getProjectId() {
        return projectId;
    }

    public void setProjectId(String projectId) {
        this.projectId = projectId;
    }

    public String getUnit() {
        return unit;
    }

    public void setUnit(String unit) {
        this.unit = unit;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }
}

インデックスを作成しようとすると、次のエラーが表示されます

java.lang.IllegalArgumentException: 無効な形式: "1461223048000" は "8000" で不正な形式です

マッピングからフォーマットを削除すると、strict_date_optional_time ||がかかります。フォーマットのデフォルトはepoch_millisですが、私はそれを望んでいません。

ここで何が間違っていますか?どうすれば解決できますか?

マッピングを次のように変更すると:

{
    "field": {
        "dynamic_templates": [{
            "notanalyzed": {
                "match": "*",
                "match_mapping_type": "string",
                "mapping": {
                    "type": "string",
                    "index": "not_analyzed"
                }
            }
        }],
        "properties": {
            "createdOn": {
                "type": "date",
                "format": "strict_date_hour_minute_second || epoch_millis"
            },
            "lastUpdatedOn": {
                "type": "date",
                "format": "strict_date_hour_minute_second || epoch_millis"
            }
        }
    }
}

そして私のクラスは：

package be.smartask.core.api.data;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author Glenn Van Schil
 *         Created on 19/04/2016
 */
public class AbstractData {
    private String id;
    private Date createdOn;
    private Date lastUpdatedOn;

    public AbstractData() {
    }

    public AbstractData(Date createdOn, String id, Date lastUpdatedOn) {
        this.createdOn = createdOn;
        this.id = id;
        this.lastUpdatedOn = lastUpdatedOn;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public Date getCreatedOn() {
        return createdOn;
    }

    public void setCreatedOn(Date createdOn) {
        this.createdOn = createdOn;
    }

    public Date getLastUpdatedOn() {
        return lastUpdatedOn;
    }

    public void setLastUpdatedOn(Date lastUpdatedOn) {
        this.lastUpdatedOn = lastUpdatedOn;
    }
}

それは機能しますが、 ||なしで行うことを好みます epoch_millis . それを取り除く方法はありますか？
