ここで暗号化されたkeyはsmkldospdosldaaaで、32ビット以上に変更するとjava.security.InvalidKeyException:Illegal key sizeと報告されます.  解決策:  対応するjarファイルをダウンロードして既存のものを置き換え、  jdk 1.8http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html.  他のバージョンと同様に、ダウンロード後に解凍し、主にlocal_に使用されます.义齿export_policy.jar、JAVAにコピーHOMEの下のjrelibsecurityに置き換えると、  私は即構人形機で使っています.彼はjsonの列をAESで暗号化する必要があります.
