elasticsearch - IllegalStateException用于混淆字段类型

Question

我的JSON(TMPOI_TEMPLATE)

{
"addressInfo": {
    "geopoint": {
        "lon": 48.845877,
        "lat": 8.821861,
    }
},
"poiLocation": {
    "geopoint": {
        "lon": 48.845877,
        "lat": 8.821861,
    },
    "speed": 3.0,
    "date": 1461067375605
},
"_id": "f212949c-7b67-45db-9f76-fe18bf951722"
}

我的 map (TMPOI_MAPPING)

{
"trafficmeasurepoi": {
      "properties": {
        "addressInfo": {
            "properties": {
                "geopoint": { "type" : "geo_point" },
            }
        },
        "poiLocation": {
            "properties": {
                "geopoint": { "type" : "geo_point" },
                "speed": { "type" : "double"},
                "date": { "type" : "date"}
            }
        }
     }
   }
}

我填写索引的方法

索引是通过另一种称为 createIndex()的方法创建的。它的工作正常。但是，当我尝试通过以下代码填充索引时，我会收到 错误

private void fillIndex()
{
    // fill index with tmpoi data
    Map<String, Object> tmpoi = JsonLoaderUtil.loadJson(TMPOI_TEMPLATE);
    String tmPoiId = (String) tmpoi.get("_id");
    IndexRequestBuilder req = client.prepareIndex(INDEX_NAME, TMPOI_TYPE, tmPoiId).setSource(tmpoi);
    req.setRefresh(true);
    IndexResponse res = req.execute().actionGet();
}   

错误

MapperParsingException[failed to parse]; nested: IllegalStateException[Mixing up field types: class org.elasticsearch.index.mapper.core.StringFieldMapper$StringFieldType != class org.elasticsearch.index.mapper.internal.IdFieldMapper$IdFieldType on field _id];

Answer 1

_id是保留字段。尝试从TMPOI_TEMPLATE中删除以下行(“_id”:“f212949c-7b67-45db-9f76-fe18bf951722”)，然后找到另一种传递文档ID的方法。
希望能帮助到你。
