私はビルドパスにジャクソン2.2.3を取得しましたが、それでもこのエラーが発生します。誰もがなぜ知っていますか?

追加する必要がありますjackson-mapper-asl
をクラスパスに追加します。
あなたはそれを見つけることができます ここ
例外は、他のライブラリまたはフレームワークがJackson 1.xを使用しており、1.x jarが必要であることを示しています。ジャクソン2.xを使用しています。そのクラスはcom.fasterxml.jackson
パッケージ;しかし例外として、org.codehaus.jackson
が必要です。
ビルドパスを設定した場合でも、実行時にクラスパスを追加する必要があります。 Eclipseでデプロイメントアセンブリを確認する
