ベロシティを使用して、送信する電子メール用の HTML テンプレート ベースのコンテンツを生成し、Java Mail APIと Spring のMimeMessageHelperを使用して電子メールを送信しています。私が直面している問題は、レンダリング中に HTML テンプレートがスローされcatalina.out、ファイルのサイズが大きくなり、望ましくないことです。
ログが生成される別のアプリケーション ログ ファイルがあります。このレンダリングをアプリケーション ログ ファイルにリダイレクトする方法はありますか? または、これが投げられるのを止めることができるかもしれませんcatalina.out。
以下は、電子メールの送信中に書き込まれる詳細です
