我想将afro中的主题从kafka索引为elasticsearch格式，但是我的时间戳字段有问题，elasticsearch会将其识别为日期格式字段。

我对连接器使用了以下配置。

   {
          "name": "es-sink-barchart-10",
      "config": {
        "connector.class": "io.confluent.connect.elasticsearch.ElasticsearchSinkConnector",
        "value.converter": "io.confluent.connect.avro.AvroConverter",
        "key.converter": "io.confluent.connect.avro.AvroConverter",
        "key.converter.schema.registry.url": "http://localhost:8081",
        "value.converter.schema.registry.url": "http://localhost:8081",

        "connection.url": "http://localhost:9200",

        "type.name":"type.name=kafka-connect",

        "topics": "exchange_avro_01",

        "topic.index.map": "exchange_avro_01:exchange_barchart",

        "key.ignore": "true"
     }
    }

原始字段是bigint类型，我希望目标字段是具有Elasticsearch的任何有效格式的日期类型。我定义了一个动态模板，尝试通过以下方式解决它：

curl -XPUT "http://localhost:9200/_template/kafkaconnect/" -H 'Content-Type: application/json' -d'
{
  "index_patterns": "exchange*",
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "kafka-connect": {
      "dynamic_templates": [
    {
          "dates": {
        "match_mapping_type": "long",
            "match": "TIME",
            "mapping": {
              "type": "date",
          "format": "yyyy-MM-dd HH:mm:ss"
            }
          }
        }
      ]
     ,
      "properties": {
          "CLOSE": {
            "type": "double"
          },
         .
         .
         .
        }
      }

    }
  }
}'

当我加载上述连接器时，没有任何东西索引到Elasticsearch。

有什么帮助吗？
