私はMongo java非同期ドライバv3.2を使用して、次のテストを行っています。コールバックが呼び出されたことがわかります（MongoコレクションのinsertOne呼び出しで登録されたもの）。テストクライアントがmongosプロセス（最後に添付されたログ）に接続できることがわかります。私はモンゴでは何の書類も見ない。シャーディング用のデータベースコレクションを有効にして、mongosプロセスからshard statusコマンドを実行することもできます。セットアップで誤って設定されている可能性のある考えはありますか？文書をmongoシャードに挿入する
CountDownLatch latch = new CountDownLatch(1);
SingleResultCallback<Void> callbackWhenFinished = new SingleResultCallback<Void>() {
@Override
public void onResult(final Void result, final Throwable t) {
System.out.println("Operation Finished!");
latch.countDown();
}
};
final Document doc = new Document("name", "MongoDB")
.append("type", "database")
.append("count", 1)
.append("info", new Document("x", 203).append("y", 102));
collection.insertOne(doc, callbackWhenFinished);
latch.await();
