マルチスレッド環境を使用して HTTP 接続プールを実現する必要があります。以下のコードを使用しています。上記の serviceURL の応答には約 1 ～ 3 秒かかりますが、クライアントから毎秒約 30 ～ 50 のヒットが発生しています。異なるプロパティを持つ単一の URL をヒットする必要があります。すべてのヒット (30 ～ 40 ヒット/秒) に応答するにはどうすればよいかわかりません。HttpURLConnection がすでに接続プールを行っている場合、マルチスレッドがその解決策です。
HTTPClient を使用してこのプログラムを変換しようとしましたが、残念ながら正しく動作しません。マルチスレッド環境を使用して、このコードを HTTPClient に変換する方法を教えてください。
