java.lang.ClassNotFoundException：org.codehaus.jackson.map.JsonSerializableWithType

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。

StaxMan

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
