我試圖運(yùn)行簽名代碼兩次，但我發(fā)現(xiàn)它只是一般的 sig1.xml ，而不是 sig1.xml 和 sig2.xml 。char password[] = "test".toCharArray();File file = new File("test.pfx");KeyStore keystore = KeyStore.getInstance("PKCS12");FileInputStream fis = new FileInputStream(file);keystore.load(fis, password);fis.close();// extracting private key and certificateString alias = "xyz"; // alias of the keystore entryKey key = keystore.getKey(alias, password);X509Certificate x509 = (X509Certificate)keystore.getCertificate(alias);// filling the SignatureConfig entries (minimum fields, more options are available ...)SignatureConfig signatureConfig = new SignatureConfig();signatureConfig.setKey(keyPair.getPrivate());signatureConfig.setSigningCertificateChain(Collections.singletonList(x509));OPCPackage pkg = OPCPackage.open(..., PackageAccess.READ_WRITE);signatureConfig.setOpcPackage(pkg);// adding the signature document to the packageSignatureInfo si = new SignatureInfo();si.setSignatureConfig(signatureConfig);si.confirmSignature();
