可以通过以下代码实现将Apache POI和iText库用于将Java Office文档转换为PDF:
```
//load the Document
FileInputStream input = new FileInputStream(new File("document.docx"));
XWPFDocument doc = new XWPFDocument(input);
//Set up the PdfWriter
FileOutputStream out = new FileOutputStream(new File("document.pdf"));
PdfWriter writer = PdfWriter.getInstance(document, out);
document.open();
//Add Paragraphs, Tables, and Images to the PDF
List<XWPFParagraph> paragraphs = doc.getParagraphs();
for(XWPFParagraph paragraph: paragraphs) {
Paragraph pdfP = new Paragraph(paragraph.getParagraphText());
document.add(pdfP);
}
List<XWPFTable> tablesList = doc.getTables();
for (XWPFTable table : tablesList) {
PdfPTable pdfTable = new PdfPTable(table.getNumberOfRows());
table.getRows().forEach(row -> {
row.getTableCells().forEach(cell -> {
PdfPCell pdfCell = new PdfPCell(new Phrase(cell.getText()));
pdfTable.addCell(pdfCell);
});
});
document.add(pdfTable);
}
List<XWPFPictureData> picList = doc.getAllPictures();
for (XWPFPictureData pic : picList) {
byte[] picData = pic.getData();
Image pdfImg = Image.getInstance(picData);
document.add(pdfImg);
}
document.close();
out.close();
input.close();
```
