java - maven-tomcat-pluginを使用して複数のTomcatインスタンスを開始します

Question

スイングアプリケーションの統合テストを実行するには、同じWebアプリケーションで構成が異なる（スプリング+システムプロパティを介して注入された）3つのtomcatを起動する必要があります。

サーバー側アプリのWARとswingアプリのJARの両方をフェッチし、3つの異なるポートセットで3つのTomcatインスタンスを起動し、それらのTomcatにWARをデプロイしてテストを実行する、このテスト専用のMavenプロジェクトがあります。

これが私たちのMaven構成です：

ログには特に何も表示されていませんが、最初に開始されたサーバーを対象とするテストのみが成功し、他のテストは失敗し、理由がわかりません（Springコンテキストが正しく開始されなかったと思われますが、できませんでした）必ず）。最初のプラグインの実行をコメントアウトすると、このサーバーを対象とするすべてのテストは（明らかに）失敗しますが、リスト内の次のサーバーを対象とするテストは合格します。

この構成の何が問題になっているのか分かりますか？私たちがここで試みていることを達成するための適切な方法は何ですか？

編集：実際には、ログにエラーがありますが、それを理解する方法がわかりません：

Answer 1

問題は、同じクラスローダーで jndi コンテキストを 2 回開始することです。これは現在、tomcat では不可能です。

Answer 2

Jetty + Tomcat だけを使用するのはどうですか?

プラグインでは、必要なだけ多くのインスタンスに Tomcat を使用できません。ただし、maven-jetty-plugin を使用して、少なくとも 2 つのアプリケーションを同時に開始できます。
