如何使用Apache POI为docx文件中的段落设置标题样式？

我正在尝试使用poi创建一个docx文件，但我无法为段落设置标题样式。

XWPFDocument document= new XWPFDocument(); //Write the Document in file system FileOutputStream out = new FileOutputStream(new File("C:/Users/2/Desktop/RequirementModelDocument.docx")); XWPFParagraph paragraph = document.createParagraph(); XWPFRun run=paragraph.createRun(); paragraph.setAlignment(ParagraphAlignment.LEFT); paragraph.setStyle("Heading1"); run.setText(reqLevel.getName()); run.setBold(true); run.setFontFamily("Calibri Light (Headings)"); 

它就像忽略了paragraph.setStyle("Heading1"); 线。 我看过apache的例子，但我看不到任何关于这个问题的例子。

如果您启动一个新文档，则没有定义样式。 从现有模板开始并复制样式，或者创建自己的样式（就像我做的那样，基于https://stackoverflow.com/a/27864752/461499 ）

看这里：

  XWPFDocument document = new XWPFDocument(); XWPFStyles styles = document.createStyles(); String heading1 = "My Heading 1"; String heading2 = "My Heading 2"; String heading3 = "My Heading 3"; String heading4 = "My Heading 4"; addCustomHeadingStyle(document, styles, heading1, 1, 36, "4288BC"); addCustomHeadingStyle(document, styles, heading2, 2, 28, "4288BC"); addCustomHeadingStyle(document, styles, heading3, 3, 24, "4288BC"); addCustomHeadingStyle(document, styles, heading4, 4, 20, "000000"); XWPFParagraph paragraph = document.createParagraph(); paragraph.setStyle(heading1); XWPFRun run = paragraph.createRun(); run.setText("Nice header!"); 

和

 private static void addCustomHeadingStyle(XWPFDocument docxDocument, XWPFStyles styles, String strStyleId, int headingLevel, int pointSize, String hexColor) { CTStyle ctStyle = CTStyle.Factory.newInstance(); ctStyle.setStyleId(strStyleId); CTString styleName = CTString.Factory.newInstance(); styleName.setVal(strStyleId); ctStyle.setName(styleName); CTDecimalNumber indentNumber = CTDecimalNumber.Factory.newInstance(); indentNumber.setVal(BigInteger.valueOf(headingLevel)); // lower number > style is more prominent in the formats bar ctStyle.setUiPriority(indentNumber); CTOnOff onoffnull = CTOnOff.Factory.newInstance(); ctStyle.setUnhideWhenUsed(onoffnull); // style shows up in the formats bar ctStyle.setQFormat(onoffnull); // style defines a heading of the given level CTPPr ppr = CTPPr.Factory.newInstance(); ppr.setOutlineLvl(indentNumber); ctStyle.setPPr(ppr); XWPFStyle style = new XWPFStyle(ctStyle); CTHpsMeasure size = CTHpsMeasure.Factory.newInstance(); size.setVal(new BigInteger(String.valueOf(pointSize))); CTHpsMeasure size2 = CTHpsMeasure.Factory.newInstance(); size2.setVal(new BigInteger("24")); CTFonts fonts = CTFonts.Factory.newInstance(); fonts.setAscii("Loma" ); CTRPr rpr = CTRPr.Factory.newInstance(); rpr.setRFonts(fonts); rpr.setSz(size); rpr.setSzCs(size2); CTColor color=CTColor.Factory.newInstance(); color.setVal(hexToBytes(hexColor)); rpr.setColor(color); style.getCTStyle().setRPr(rpr); // is a null op if already defined style.setType(STStyleType.PARAGRAPH); styles.addStyle(style); } public static byte[] hexToBytes(String hexString) { HexBinaryAdapter adapter = new HexBinaryAdapter(); byte[] bytes = adapter.unmarshal(hexString); return bytes; }

我在下面的链接中找到了一个解决方案。 抱歉复制。

如何在带有POI的DOCX中使用预定义格式？

但是，如果你有任何其他解决方案没有使用模板文件，请告诉我:)
