pdf获取电子签章信息报错java.security.NoSuchAlgorithmException: 2.16.840.1.101.3.4.2.1withRSA Signature not available

在获取pdf电子签章信息中报了个错，java.security.NoSuchAlgorithmException: 2.16.840.1.101.3.4.2.1withRSA Signature not available，签名不可用，百度了一些大佬的相关问题还是没有解决，有大佬知道怎么解决吗

 System.out.println("\n\nTestMGomez.pdf\n==============");
        setUp();
        try (InputStream resource = testOne.class.getResourceAsStream("TestMGomez.pdf")) {
            PdfReader reader = new PdfReader(resource);
            AcroFields acroFields = reader.getAcroFields();

            List<String> names = acroFields.getSignatureNames();
            for (String name : names) {
                System.out.println("Signature name: " + name);
                System.out.println("Signature covers whole document: " + acroFields.signatureCoversWholeDocument(name));
                PdfPKCS7 pk = acroFields.verifySignature(name);
                System.out.println("Subject: " + CertificateInfo.getSubjectFields(pk.getSigningCertificate()));
                System.out.println("Document verifies: " + pk.verify());
