Spacing and Margin settings in MS Word document using Apache POI docx

Question

I have two paragraphs and i want 100 pt space before each line. Is there a way we can do in Apache POI?

Here is the code snippet

XWPFDocument doc = new XWPFDocument();
XWPFParagraph documentTitle = doc.createParagraph();

documentTitle.setAlignment(ParagraphAlignment.CENTER);
XWPFRun run = documentTitle.createRun();

run.setText("Paragraph 1");
run.setBold(true);
run.setFontFamily("Calibri");
run.setFontSize(13);
run.setColor("4F81BD");

run.addBreak();

run.setText("Paragraph 2");
run.setBold(true);
run.setFontFamily("Calibri");
run.setFontSize(13);
run.setColor("4F81BD");

Here how to add 100 pt space between two paragraphs? Is there any way we can achieve this? addBreak() is not keeping any space between two lines.

And how to set margin spacing in docx?

Any help would be appreciated.

Thanks.

Solution

Got the answer..

    documentTitle.setAlignment(ParagraphAlignment.CENTER);
    // This does the trick
    documentTitle.setSpacingBefore(100);

It left me 100pt space between each line of the text

If you want to add custom margins to your document. use this code.

    CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();
    CTPageMar pageMar = sectPr.addNewPgMar();
    pageMar.setLeft(BigInteger.valueOf(720L));
    pageMar.setTop(BigInteger.valueOf(1440L));
    pageMar.setRight(BigInteger.valueOf(720L));
    pageMar.setBottom(BigInteger.valueOf(1440L));
