1. Key points
Two methods, Method 1: Use documents4j to convert word to pdf, but it is not friendly to the Linux system. There are pitfalls and pitfalls. Don’t ask. The question is that I used documents4j from the beginning. As a result, I found that I could not convert pdf when I updated the version. Looking for information in the log, I found that Linux is not supported. If you want to support Linux but the process is cumbersome, you need to install offic components on Linux. If you don't mind the trouble, you can try to find information on how to install offic components. Method 2: Based on aspose-words, it is powerful and can be used perfectly on Linux. The disadvantage is that it is paid. If conditions permit, it is recommended to ignore the license.xml below and use the genuine version. I used method 2, the reference is as follows:
2. Method 2 (based on aspose-words)
1.jar download
First, you need the aspose-words-15.8.0-jdk16.jar package. An old man provided the resources.

2.Put the jar into the local warehouse
<dependency>
<groupId>com.aspose</groupId>
<artifactId>words</artifactId>
<version>15.8.0</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.4.3</version>
</dependency>
mvn install:install-file -Dfile="E:\安装包\Java\aspose-words-15.8.0-jdk16.jar" -DgroupId=com.aspose -DartifactId=words -Dversion=15.8.0 -Dpackaging=jar
Note:
-Dfile is the local path where you downloaded the jar
-DgroupId is the groupId in dependency
-DartifactId is the artifactId in dependency
-Dversion is the version in dependency
3.Introduce license.xml
Create the license.xml file yourself and place it anywhere under resources

4.pdfUtil tool class
/** * Generate pdf document * @param Address The source file address is such as /root/example.doc * @param Address1 The target file address is such as /root/example.pdf */public class PdfUtil { public static void doc2pdf(String Address,String Address1) { //Verify the License. If not verified, the converted pdf document will have a watermark if (!getLicense()) { return; } try { //Create a new one Blank pdf document long old = System.currentTimeMillis(); File file = new File(Address1); FileOutputStream os = new FileOutputStream(file); //Address is the word document to be converted Document doc = new Document(Address); / / Fully supports DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF mutual conversion doc.save(os, SaveFormat.PDF); long now = System.currentTimeMillis(); //Conversion time System.out.println("Total time spent: " + ((now - old) / 1000.0) + "seconds"); } catch (Exception e) { e.printStackTrace(); } }}
5. After converting the pdf, stamp the pdf with a table with 3 rows and 1 column, as shown below:
PdfUtil.doc2pdf(file, pdf);
PDDocument document = PDDocument.load(new File(pdf));
// Get the first page
of PDPage firstPage = document.getPage(0);
PDFont font = PDType0Font.load(document, new File (FILE_BASE_URL + File.separator + FILE_DEMO_URL + File.separator + "Fangzhengshu Song.TTF"));
// Get the page size
PDRectangle pageSize = firstPage.getMediaBox();
float pageWidth = pageSize.getWidth();
float pageHeight = pageSize .getHeight();
// Create content stream
PDPageContentStream contentStream = new PDPageContentStream(document, firstPage, PDPageContentStream.AppendMode.APPEND, true, true);
// Set text font and size
contentStream.setFont(PDType1Font.HELVETICA_BOLD, 12);
contentStream.setNonStrokingColor(0, 0, 255);
/ / Set line color to blue
contentStream.setStrokingColor(0, 0, 255);
// Draw the inner and outer wireframe
float startX = 80; // Starting X coordinate
float startY = pageHeight - 80; // Starting Y coordinate
float cellWidth = 100; // Cell Width
float cellHeight = 20; // Cell height
// Draw table seal
for (int i = 0; i < 3; i++) {
float x = startX;
float y = startY - (i * cellHeight);
contentStream.addRect( x, y, cellWidth, cellHeight);
contentStream.stroke();
String text = "";
// Add text
if (i == 0) {
text = " **** ";
}
if (i == 1) {
text = "**** (" + filingDetails.getFilingYear() + ")" + filingDetails.getNum() + "number";
if
(i == 2) {
text = " ***** ";
}
contentStream.beginText();
contentStream.newLineAtOffset(x + 5, y + 5);
contentStream.setFont(font, 8);
contentStream.showText(new String(text.getBytes(StandardCharsets.UTF_8), StandardCharsets.UTF_8));
contentStream.endText();
}
contentStream.close();
// Save the modified PDF file
document.save(pdf);
document.close();
// Export pdf to
String pdfName = pdf.substring(file.lastIndexOf( "/") + 1);
CommonUtils.setResponseHeader(response, pdfName);
InputStream is = Files.newInputStream(Paths.get(pdf));
OutputStream os = new BufferedOutputStream(response.getOutputStream());
//Create an array byte[] to store the file content
buff = new byte[1024];
//The read content uses n to receive
int n;
//When the reading is not completed, continue reading and loop
while (( n = is.read(buff)) != -1) {
//Write all the byte array data into the output stream
os.write(buff, 0, n);
}
os.flush();
os. close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
