私はmavenが初めてです。初めてプロジェクトを実行すると、コンソールにこの出力が表示されます

日食を閉じて再度開始すると、プロジェクトは初めて正常に動作します。

回答 : これに対する回答は、コマンド ラインから tomcat を停止するか、elipse を再起動するか、ポート番号を変更することです。

eclipse に m2e プラグインをインストールしたばかりなので、コマンド ラインから停止できません。毎回Eclipseを再起動してポート番号を変更したくありません。これを行う他の方法はありますか？Eclipse から Tomcat を停止または開始することはできませんか?

java.net.BindException: アドレスは既に使用されています

すでに実行されている tomcat のインスタンスを閉じておらず、再度実行しようとしているために、この問題が発生しています。

したがって、最初のインスタンスを閉じて再実行し、問題が解決しない場合は、次の方法でポートを変更することができます。

server.xml を開いて 8080 を検索し、8081 に変更します。

Tomcatを閉じるには、この回答を確認してください

mvn tomcat:stop

tomcat:start の前にこれを使用します。

コンソール ビューを参照してください。アプリケーションを停止するための赤いボタンがあります。

こちらのドキュメントをご覧ください
