Question

我正在使用itext 5.5.13。我有一个现有的pdf文件，我正在尝试使用java将一些数据添加到pdf文件中的acrofields中。这是我的代码。当我使用itext 2.x而不是5.5.13时，这是完美的工作方式。在pdfStamper.close（）之后，代码的其余部分将不执行，而将直接转到调用此方法的代码的finally块。

private byte[] get1099PdfForm(RI1099DataDTO ri1099DataDTO) throws Exception {
log.debug("Enter generateForm()");
byte[] imageData = null;
PdfReader pdfReader = null;
PdfStamper pdfStamper = null;
File newFile = null;
try {
//New Pdf file
int randomNum = new Double((Math.random() * 1000000)).intValue();
newFile = File.createTempFile(String.valueOf (randomNum), ".pdf");
newFile.deleteOnExit();

//String year = DateUtils.toString(new Date (), "yyyy");

//Read existing pdf template
pdfReader = new PdfReader(ri1099DataDTO.getTax_Year() + "_" + _templateName);

//Create instance of Pdf Stampler
pdfStamper = new PdfStamper(pdfReader, new FileOutputStream(newFile, false));

//Get acro fields
AcroFields pdfFormFields = pdfStamper.getAcroFields();

//Map form fields
this.mapFormFields(pdfFormFields, ri1099DataDTO);

//Set form flattening to true
pdfStamper.setFormFlattening(true);

// close the pdf
pdfStamper.close();
 //Return stream
imageData = new byte[(int) newFile.length()];
@SuppressWarnings("resource")
FileInputStream fileInputStream = new FileInputStream(newFile);
fileInputStream.read(imageData);
} catch (Exception e) {
log.error("Error occured while generating form for job <TaxYear=" + ri1099DataDTO.getTax_Year() + "/Compay=" + ri1099DataDTO.getCompany() + "/TaxID", e);
throw e;
}
log.debug("Exit generateForm()");
return imageData;
}
