使用spring和pdfbox apache库我已在控制器中编辑了PDF,但也不确定如何将此pdf保存到classpath,以便我可以将保存的pdf转换为字节并将其传递给服务。
感谢任何帮助。谢谢。
我的控制器代码如下:
@RequestMapping("/individual/load/editablePDF.do")
public void getFile(HttpServletRequest request,HttpServletResponse response) throws IOException {
Resource resource = new ClassPathResource("EditableFile.pdf");
InputStream resourceInputStream = resource.getInputStream();
PDDocument pdfDoc = PDDocument.load(resourceInputStream);
PDDocumentCatalog docCatalog = pdfDoc.getDocumentCatalog();
PDAcroForm acroForm = docCatalog.getAcroForm();
List<PDField> fieldList = acroForm.getFields();
String[] fieldArray = new String[fieldList.size()];
int i = 0;
for (PDField sField : fieldList) {
fieldArray[i] = sField.getFullyQualifiedName();
i++;
}
for (String f : fieldArray) {
PDField field = acroForm.getField(f);
System.out.println("f is: " + f);
if (f.contains("company name")) {
String value = "Discovery";
field.setValue(value);
System.out.println("printed: " + value + " to: " + f);
}
}
try {
pdfDoc.save("D:\\workspace\\TestSamples\\src\\Editable_ Discovery wellness days application form 2017-SAVED.pdf");//Not sure how to achieve this?
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pdfDoc.close();
}
