Apache Camel / Smallrye / reactiveストリームの使用-JVM間で「パブリッシャー」を「サブスクライバー」に接続するにはどうすればよいですか？

Question

以下は、Apache Camelリアクティブストリームソリューションで、JVM全体でパブリッシャーをサブスクライバーに接続する（ラクダルートのコードを以下に示す）試みです。

通信がJVMにまたがるようにするには、「ブローカー」サーバーが必要なようです。したがって、Artemisブローカーを実装し、それに応じてapplication.propertiesファイルを変更しました（その方法についての私の理解のとおり）。

また、焦点を絞るために、smallrye-ampqコネクタの使用を選択しました。

問題：

サブスクライバーは（本文から）文字列値を受信して​​ログに記録する必要があります。

-
-
-
:blahblahblah
:blahblahblah
:blahblahblah
-
-
-

-代わりに、次のように値をログに記録します。

-
-
-
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-289]
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-292]
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-295]
-

-

質問：

パブリッシャーがペイロードを送信してサブスクライバーに到達しないのはなぜですか？それを修正するためにどのコード/構成を変更できますか？

事前にt​​hxをお寄せください。

Answer 1

したがって、メソッドシグネチャを...から変更することがわかります。

@Outgoing("data")
public Publisher<Exchange> source() {
    ...
}

に...

@Outgoing("data")
public Publisher<String> source() {
    ...
}

Answer 2

あなたがあなたの投稿で述べた問題は、問題を解決するためのいくつかの明確に定義されたパターンを持つかなり一般的なユースケースであり、この場合は Apache ActiveMQ =、 RabbitMQ 、 Apache Kafka など。そうすることで、記事で述べたように、キャメルコンテキストを分離するための完全な方法を提供します 複数のキャメルコンテキストを使用する理由？ この概念については、 Apache CamelMessage Channel EIP （EIP = Enterprise Integration Pattern ）のドキュメントで詳しく説明しています。

上記の投稿で、あなたは Camel SEDA を使おうとしているようです。そのドキュメントページは述べています：

キューは単一のCamelContext内でのみ表示されることに注意してください。 CamelContextインスタンス間で通信する場合（Webアプリケーション間の通信など）は、VMコンポーネントを参照してください。

VMがメッセージの処理中にまだ終了している場合、このコンポーネントはいかなる種類の持続性または回復も実装しません。持続性、信頼性、または分散SEDAが必要な場合は、JMSまたはActiveMQを使用してみてください。

Camel VM component は、複数のCamelコンテキストが異なるサーバーに分散されているため、ここでも機能しません。VMコンポーネント複数のCamelコンテキスト間で実行できますが、相互通信するためには、それらはすべて同じJVM内で実行されている必要があります。

これらの理由から、この場合、メッセージングミドルウェアのようなものを使用する方法はありません。

ストリーミングについて言及したので、 Apache Kafka のようなものが良い選択かもしれません。私はこれについてこれまで作業したことがなく、これについてこれ以上コメントすることはできませんでしたが、私はフェラがそれについて語っている記事を見つけました（ Apache Kafkaのリアクティブストリーム を参照）。キャメルには Kafka Component があり、すべてを一緒に配線するために使用できます。

一般的な単純なラクダの答えではありませんが、RSocketはネットワーク全体にRXプログラミングモデルを実装しています（TCPソケット、HTTP Webソケットなどの上に））。

https://github.com/rsocket/rsocket-Java

Spring Bootのようなアプリフレームワークで十分にサポートされています。しかし、それはあなたが求めている単純に機能する例ではありません。
