Elasticsearchの使用中にorg.elasticsearch.common.xcontent.DeprecationHandler例外REST高レベルクライアント

Elasticsearchハイレストクライアントを使用しようとすると、次の例外が発生します。

Spring Boot2.0.4およびElasticsearch6.4バージョンを使用しています。ユースケースは、単にいくつかのデータを使用してインデックスを作成し、それを取得することです。

dependencies のelasticsearchドキュメントに従い、正しく設定しました。

私のGradle依存関係は

dependencies {
   compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.4.0'
}

簡単にするために、コードの短いバージョンを考えます。

@RestController
public class ElasticController {

@RequestMapping("/posts")
public void getData() {

    RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("localhost", "9200","http")));

    GetRequest request = new GetRequest("posts", "doc", "1");
    GetResponse response = client.get(request, RequestOptions.DEFAULT);

    System.out.println(response.getSource().toString());

}
}

誰かがこれを手伝ってくれる？

はい、次のことがわかりました link 問題を突き止めるのに役立ちます。

Elasticsearch documentation に従って、「elasticsearch-rest-high-level-client」依存関係を追加するだけで済みます。ただし、Gradleビルドで、バージョン番号が小さい他の依存関係を取得することを確認しました。私の場合は5.6.10です

enter image description here

今、build.gradleに次の依存関係も追加しました。

dependencies {
    compile group: 'org.elasticsearch', name: 'elasticsearch', version: '6.4.0'
    compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-high-level-client', version: '6.4.0'
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

それはそれを解決します。他のフォーラムでも同じ問題が報告されているようですが、これが役立つことを願っています（Elasticsearchのドキュメントにもこれを含める必要があるかもしれません）。

私も同じ問題を抱えていました。ついに、org.elasticsearch:elasticsearch依存関係を提供し、rest-high-level-clientと同じバージョンを維持する必要があることがわかりました。

そうしないと、デフォルトでorg.elasticsearch:elasticsearch:5.6.10になりますが、rest-client6.4.xを使用しています。
