签署文档时出现 PDFBox 2.0.8 问题
PDFBox 2.0.8 issue while signing document
我正在尝试使用此方法签署 pdf，但得到的文档没有大小：
public static void sign(PDDocument doc) throws KeyStoreException, NoSuchAlgorithmException, CertificateException,
IOException, UnrecoverableKeyException {
System.out.println("Document pages ? " + doc.getNumberOfPages());
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(VisibleSignature.class.getResourceAsStream(CERT_FILE), ALIAS_PASS);
System.out.println("KeyStore is null ? " + (ks == null));
VisibleSignature vs = new VisibleSignature(ks, ALIAS_PASS.clone());
InputStream is = Resource.get(IMAGE_FILE);
int page = 1;
vs.setVisibleSignDesigner(doc, 0, 0, -50, is, page);
is.close();
vs.setVisibleSignatureProperties("Test", "Test", "Test", 0, page, true);
PDSignature signature = new PDSignature();
PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
System.out.println("Acroform is null ? " + (acroForm == null));
System.out.println("Acroform getNeedAppearances ? " + (acroForm.getNeedAppearances()));
if (acroForm != null && acroForm.getNeedAppearances())
if (acroForm.getFields().isEmpty())
acroForm.getCOSObject().removeItem(COSName.NEED_APPEARANCES);
else
System.out.println("/NeedAppearances is set, signature may be ignored by Adobe Reader");
signature.setFilter(PDSignature.FILTER_ADOBE_PPKLITE);
signature.setSubFilter(PDSignature.SUBFILTER_ADBE_PKCS7_DETACHED);
if (vs.visibleSignatureProperties != null) {
vs.visibleSignatureProperties.buildSignature();
signature.setName(vs.visibleSignatureProperties.getSignerName());
signature.setLocation(vs.visibleSignatureProperties.getSignerLocation());
signature.setReason(vs.visibleSignatureProperties.getSignatureReason());
System.out.println("SignerName " + vs.visibleSignatureProperties.getSignerName());
}
signature.setSignDate(Calendar.getInstance());
vs.signatureOptions = new SignatureOptions();
vs.signatureOptions.setVisualSignature(vs.visibleSignatureProperties.getVisibleSignature());
vs.signatureOptions.setPage(vs.visibleSignatureProperties.getPage() - 1);
doc.addSignature(signature, vs.signatureOptions);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
doc.saveIncremental(baos);
doc.close();
IOUtils.closeQuietly(vs.signatureOptions);
byte[] content = baos.toByteArray();
System.out.println("Content length: >>>>>>>>>>>>>>>>>>> " + content.length);
}
这是我在 eclipse 日志中得到的：

有人知道这是怎么回事吗？
在您的代码中，您没有为文档提供可用于签名的 SignatureInterface 实现。在这个用例中没有提供，PDFBox 假设您将在外部创建签名（例如查看原始 CreateVisibleSignature 方法 sign）。在这种情况下，在使用 ExternalSigningSupport 方法 setSignature 设置签名后，结果将写入输出流。如果您不这样做，您的 ByteArrayOutputStream baos 将保持为空。
但是您确实有一个 SignatureInterface 实例，您已经使用证书和密钥 material 初始化了该实例：您的 VisibleSignature vs。因此，我假设您没有提供 SignatureInterface 不是故意的。
因此，要提供 SignatureInterface，您必须使用带有 SignatureInterface 参数的 PDDocument.addSignature 重载。例如。替换你的电话
doc.addSignature(signature, vs.signatureOptions);
来自
doc.addSignature(signature, vs, vs.signatureOptions);
使您的代码按预期运行。
