Java sign pdf keystore.load引发javax.crypto.BadPaddingException

我使用在上找到的以下代码用*.p12文件为PDF签名

public static final boolean signPdf()
        throws IOException, DocumentException, Exception
{
    // Vous devez preciser ici le chemin d'acces a votre clef pkcs12
    String fileKey          = "C:\\MonRep\\MaClef.p12" ;
    // et ici sa "passPhrase"
    String fileKeyPassword  = "MonPassword" ;

    try {
        // Creation d'un KeyStore
        KeyStore ks = KeyStore.getInstance("pkcs12");
        // Chargement du certificat p12 dans el magasin
        ks.load(new FileInputStream(fileKey), fileKeyPassword.toCharArray());
        String alias = (String)ks.aliases().nextElement();
        // Recupération de la clef privée
        PrivateKey key = (PrivateKey)ks.getKey(alias, fileKeyPassword.toCharArray());
        // et de la chaine de certificats
        Certificate[] chain = ks.getCertificateChain(alias);

        // Lecture du document source
        PdfReader pdfReader = new PdfReader((new File(fname)).getAbsolutePath());
        File outputFile = new File(fnameS);
        // Creation du tampon de signature
        PdfStamper pdfStamper;
        pdfStamper = PdfStamper.createSignature(pdfReader, null, '\0', outputFile);
        PdfSignatureAppearance sap = pdfStamper.getSignatureAppearance();
        sap.setCrypto(key, chain, null, PdfSignatureAppearance.SELF_SIGNED);
        sap.setReason("Test SignPDF berthou.mc");
        sap.setLocation("");
        // Position du tampon sur la page (ici en bas a gauche page 1)
        sap.setVisibleSignature(new Rectangle(10, 10, 50, 30), 1, "sign_rbl");

        pdfStamper.setFormFlattening(true);
        pdfStamper.close();

        return true;
    }
    catch (Exception key) {
        throw new Exception(key);
    }
}

代码在我的电脑上运行良好。但是如果我使用eclipse创建一个.war文件并将其部署到服务器上，服务器会抛出一个javax.crypto.BadPaddingException：

我在其他线程中找到的所有信息都表明我用来加载密钥库的密码是错误的，但我确信它没有错

有什么想法吗？

多谢各位

您是否正在使用所有依赖项创建战争？您必须将所有库附加到WAR文件以使其独立工作。您是否有证据证明密码正确？它真的是PKCS#12密钥库吗？是的，eclipse war导出包含所有依赖项。我确信密码是正确的，因为我在我的计算机上使用相同的.p12文件和密码测试了代码，并且签名工作正常
