私の以前のバージョンのactivitiは5.11で、今は5.21.0にアップデートしようとしています。以前の設定では、restletサーブレットが使用されます。今私はwebconfigurer.classで設定しようとしています。 web.xmlにリスナーを挿入しました。しかし、それはエラーを投げる。webconfigurer.classでactiviti 5.21.0を設定する方法
のweb.xmlエントリ
<listener><listener-class>org.activiti.rest.servlet.WebConfigurer</listener-class></listener>
エラー：

設定の詳細を投稿できますか？依存関係としてactiviti-restを含めましたか？これはActivitiのWebアプリケーションプロジェクトでも行いますが、実際にweb.xmlにリスナーを追加します：https://github.com/Activiti/Activiti/blob/master/modules/activiti-webapp-rest2/src/ main/webapp/WEB-INF/web.xml＃L21 –
