Question

在我的javascript中，我有以下代码：

      var encrypted = CryptoJS.AES.encrypt("Message that I am trying to send !", k, { mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7, iv:i });
    console.log("Cipher Text");
console.log(encrypted.ciphertext.toString(CryptoJS.enc.Base64));
 //prints out: 1e9z0zjI9MGBLW6AdLE+BiVnv9R9lDAS+SmSkX/Ufx7zTHOVanpiwd4IC2XejJaq
    console.log("Key: " + k);
//prints out f7710e2bcf419dab
    console.log("Iv: " + i);
// prints out 42d39acea111ceb2

这是我在java方面的解密代码：

 import java.io.UnsupportedEncodingException;
    import java.security.InvalidAlgorithmParameterException;
    import java.security.InvalidKeyException;
    import java.security.Key;
    import java.security.NoSuchAlgorithmException;
    import java.security.Security;
    import java.security.spec.AlgorithmParameterSpec;

    import org.apache.commons.codec.binary.BaseNCodec;
    import javax.crypto.BadPaddingException;
    import javax.crypto.Cipher;
    import javax.crypto.IllegalBlockSizeException;
    import javax.crypto.KeyGenerator;
    import javax.crypto.NoSuchPaddingException;
    import javax.crypto.SecretKey;
    import javax.crypto.spec.IvParameterSpec;
    import javax.crypto.spec.SecretKeySpec;

        public static void main(String[] args) {
            // TODO Auto-generated method stub
            String encrypted = "1e9z0zjI9MGBLW6AdLE+BiVnv9R9lDAS+SmSkX/Ufx7zTHOVanpiwd4IC2XejJaq";
             SecretKey key = new SecretKeySpec("f7710e2bcf419dab".getBytes("UTf-8"), "AES");
                AlgorithmParameterSpec iv = new IvParameterSpec("42d39acea111ceb2".getBytes("UTf-8"));
                byte[] decodeBase64 = Base64.decodeBase64(encrypted);

                Cipher cipher = null;
                try {
                    cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
                } catch (NoSuchAlgorithmException | NoSuchPaddingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                try {
                    cipher.init(Cipher.DECRYPT_MODE, key, iv);
                } catch (InvalidKeyException | InvalidAlgorithmParameterException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

              try {
                 String s = new String(cipher.doFinal(decodeBase64).toString());
                System.out.println(s);
            } catch (IllegalBlockSizeException | BadPaddingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

当我在java端解密时，它会抛出一个execption＆＃34; javax.crypto.BadPaddingException：给定最终块没有正确填充＆＃34;马上，我最初的观察是我在加密端的填充是Pkcs7，而我在java上的填充是PKCS5Padding。我一直在互联网上搜索，填充似乎是可以互换的？有人可以解释一下我在这里做错了什么吗？
