类“org.bouncycastle.asn1.ASN1ObjectIdentifier”的签名者信息与同一包中其他类的签名者信息不匹配

Question

有人可以帮我解决这个例外吗？这是否意味着我必须使用 1.5 的 Java 版本运行 keytool？

我以前有过它，但现在我明白了。

Exception in thread "main" java.lang.ExceptionInInitializerError
at com.itextpdf.text.pdf.security.CertificateInfo.getSubjectFields(CertificateInfo.java:356)
at com.itextpdf.text.pdf.PdfSignatureAppearance.getAppearance(PdfSignatureAppearance.java:884)
at com.itextpdf.text.pdf.PdfSignatureAppearance.preClose(PdfSignatureAppearance.java:1268)
at com.itextpdf.text.pdf.security.MakeSignature.signDetached(MakeSignature.java:140)
at org.deloitte.cms.efi.controller.signature.SignatureAppearance.sign4(SignatureAppearance.java:181)
at org.deloitte.cms.efi.controller.signature.SignatureAppearance.main(SignatureAppearance.java:208)

引起：java.lang.SecurityException：类“org.bouncycastle.asn1.ASN1ObjectIdentifier”的签名者信息与同一包中其他类的签名者信息不匹配

这是我的代码：

    public void sign4(String src, String name, String dest,
        Certificate[] chain, PrivateKey pk,
        String digestAlgorithm, String provider, CryptoStandard subfilter,
        String reason, String location)
                throws GeneralSecurityException, IOException, DocumentException {
    // Creating the reader and the stamper
    PdfReader reader = new PdfReader(src);
    FileOutputStream os = new FileOutputStream(dest);
    PdfStamper stamper = PdfStamper.createSignature(reader, os, '\0');
    // Creating the appearance
    PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
    //appearance.setReason(reason);
    //appearance.setLocation(location);
    appearance.setVisibleSignature(name);
    // Default text and scaled background image
    appearance.setImage(Image.getInstance(IMG));
    //appearance.setImageScale(-1);
    appearance.setImageScale(0);
    // Creating the signature
    PrivateKeySignature pks = new PrivateKeySignature(pk, digestAlgorithm, provider);
    ExternalDigest digest = new BouncyCastleDigest();
    MakeSignature.signDetached(appearance, digest, pks, chain, null, null, null, 0, subfilter);
}

这是我的 pom.xml

请检查您的 Maven 依赖树。您的 pom 请求 bc 版本 1.5.2，但根据http://mvnrepository.com/artifact/com.itextpdf/itextpdf/5.5.6，itext 需要版本 1.49。从你的 pom 中删除两个 bc 元素。
