mavenプロジェクトGsonの依存を追加すると起動できません.BeanCreationException:Error creating bean with name'gsonBuilder'をエラーで報告します.

具体的なエラーは次のとおりです.

プロジェクトを開始すると、新しく追加したGsonはjarパッケージに依存してエラーが発生し、異常情報を通じて資料を検索し、Gsonのバージョンの問題かもしれないと推測し、gsonBuilderを作成できなくなり、自分の元のバージョンは2.2.4だったので、https://blog.csdn.net/email_jade/article/details/72886991?utm_source=itdadao&utm_medium=referralで説明した2.6.2に従って、問題を解決します.
