スプリングブートのthymeleaf自動構成でエラーテンプレートを解決しようとすると問題が発生する

Question

My Spring Boot RESTアプリケーションでメールテンプレート用のThymeleafのみが使用されます。

残念ながら、私のブート設定では、エラーが発生したときにエラーテンプレートを解決しようとしています。以下

これは（私が唯一のメールテンプレートのThymeleafを使用しています一方）春ブーツページのためThymeleafビューリゾルバを設定していることを示していると思われます。

Springブートでメールテンプレート用のThymeleafのみを使用するようにするには、どうすれば上記の例外を回避できますか？

編集：私は私のapplication.properties

server.error.whitelabel.enabled=false 

に次の行を持っていますが、すべての違いを確認していないようです。 application.propertiesでこのプロパティを使用して

Answer 1

：

spring.thymeleaf.enabled=false 

は春のMVCのためthymeleafを無効にするようだ - まだメールテンプレートのためthymeleaf保ちながら。

スプリングブートソースコードhereを参照してください。

編集：さらに

、春ブーツで登録されているデフォルトのエラー・コントローラを無効にする必要があると思わ：hereを参照してください。

たとえば、ここで説明するカスタムエラーコントローラを実装できます。https://stackoverflow.com/a/25362790/536299
