我正在尝试使用scala elstic4s客户端将新文档索引到我的elasticsearch集群中,但我遇到了类型的编译问题。按照Web中的文档和示例,语法如下:
客户端实例化:
val settings = ImmutableSettings.settingsBuilder().put("cluster.name", Configuration.elasticsearchClusterName).build()
val uri = ElasticsearchClientUri("elasticsearch://" + Configuration.elasticsearchUri)
val client = ElasticClient.remote(settings, uri)
我想把它写成:
def writeToElasticsearch(bulkList: List[EventMessage]) {
val ops = for (message <- bulkList) yield index into indexDcp ttl 7.days.toMillis doc StringDocumentSource(message.toJSon())
client.execute(bulk(ops: _*)).await
}
我在批量操作中遇到编译错误:
Multiple markers at this line
- type mismatch; found : List[com.sksamuel.elastic4s.IndexDefinition] required:
Seq[Int]
任何人都可以告诉我如何转换类型以使其工作?谢谢!
答案 0 :(得分:0)
我不确定你为什么会收到错误,可能是你错过了代码示例中的错误,但是这个版本的代码对我来说很好。
object Test extends App {
val client = ElasticClient.local
val indexDcp = "myindex/mytype"
import scala.concurrent.duration._
import ElasticDsl._
def writeToElasticsearch(bulkList: List[EventMessage]) {
val ops = for (message <- bulkList) yield { index into indexDcp ttl 7.days.toMillis doc StringDocumentSource(message.toJSon()) }
client.execute(bulk(ops: _*)).await
}
trait EventMessage {
def toJSon(): String
}
}
