Couchbase Java APIでConnectExceptionが発生する

Question

ダミーのJSONを作成してクエリを実行しようとしています。私はJAVAを使ってそれをやっています。コードは以下の通りである： - 上記のコードを実行するには

import static com.couchbase.client.java.query.Select.select; 
import static com.couchbase.client.java.query.dsl.Expression.s; 
import static com.couchbase.client.java.query.dsl.Expression.x; 

import com.couchbase.client.java.Bucket; 
import com.couchbase.client.java.Cluster; 
import com.couchbase.client.java.CouchbaseCluster; 
import com.couchbase.client.java.document.JsonDocument; 
import com.couchbase.client.java.document.json.JsonObject; 
import com.couchbase.client.java.env.CouchbaseEnvironment; 
import com.couchbase.client.java.env.DefaultCouchbaseEnvironment; 
import com.couchbase.client.java.query.Query; 
import com.couchbase.client.java.query.Statement; 

public class AccessData { 
    public static void main(String[] args) { 
     CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder() 
       .queryEnabled(true) 
       .build(); 
     Cluster cluster = CouchbaseCluster.create(env, "127.0.0.1"); 
     Bucket bucket = cluster.openBucket("default", ""); 
     JsonObject testDataBlog = JsonObject.create().put("type", "blog").put("data", "blablabla"); 
     JsonObject testDataComment = JsonObject.create().put("type", "comment").put("data", "ho hey"); 
     bucket.upsert(JsonDocument.create("testDp4Blog", testDataBlog)); 
     bucket.upsert(JsonDocument.create("testDp4Comment", testDataComment)); 
     Statement statement = select("*").from("default").where(x("type").eq(s("blog"))); 
     Query createIndex = Query.simple("CREATE PRIMARY INDEX ON default"); 
     bucket.query(createIndex); 
     Statement withPlaceholders = select("*").from("default").where(x("type").eq(x("$1"))); 
} 
} 

が、私は次のエラーを取得しています： -

任意の手がかりはそれを修正するために？

Answer 1

かなり古くなったバージョンのサーバーとSDK、および開発者のプレビュー版を使用しているようです。

Couchbase Server 4.1.0を新規にクリーンインストールし、Java SDKを最新バージョン2.2.7で使用することを強くお勧めします。いくつかの物事が変更されています：

• を環境
• Queryを設定するときにqueryEnabled(true)を必要としませんあなたが得るエラーは、クライアントが接続しようとしたときにことを示しN1qlQuery

名前が変更されましたlocalhostでは、何も答えません（少なくともポート11210で）。ノードが正しくweb consoleにあることを確認できますか？

もう一度、4.1.0のCouchbaseをインストールすることをお勧めします。現在のインスタンスに保存する特定のデータがない場合は、完全に再インストールしてください（現在のインストールを先に削除してください。hereを参照）。
