Apache-poi Java：如何更改 WORD 文档中列表编号的字体名称和大小？

Question

我写了一个方法来为Word文档的某些段落添加编号，但是我似乎无法自定义列表编号的字体名称和字体大小（例如：a.我的项目1，b.我的项目2 ）。我可以自定义段落中的字体，但是无法自定义列表编号的字体名称和字体大小。下面的代码中是否有我可能遗漏的内容？

    public static BigInteger listNumbering(XWPFDocument doc, BigInteger abstractNumID) {
      CTAbstractNum cTAbstractNum = CTAbstractNum.Factory.newInstance();
      cTAbstractNum.setAbstractNumId(abstractNumID);

      CTLvl cTLvl = cTAbstractNum.addNewLvl();
      cTLvl.addNewNumFmt().setVal(STNumberFormat.DECIMAL);

      cTLvl.addNewLvlText().setVal("%1.");
      cTLvl.addNewStart().setVal(BigInteger.valueOf(1));

      XWPFAbstractNum abstractNum = new XWPFAbstractNum(cTAbstractNum);

      XWPFNumbering numbering = doc.createNumbering();

      abstractNumID = numbering.addAbstractNum(abstractNum);

      BigInteger numID = numbering.addNum(abstractNumID);

      return numID;
     }

Answer 1

您的代码仅为文档创建十进制编号格式并获取适当的

NumID

。然后需要将

NumID

应用到文件中应编号的段落。格式由段落决定。

编号本身的格式由段落的运行属性决定。不幸的是，到目前为止，

XWPFParagraph

中还没有方法可以设置段落运行属性。所以我们需要使用低级

ooxml-schemas

类来做到这一点。在下面的代码中，方法

setParagraphRunProperties(XWPFParagraph paragraph, String fontFamily, int fontSize)

正在执行此操作。

编号段落的格式由其文本串的格式决定。

完整示例：

import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTAbstractNum;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTLvl;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STNumberFormat;

import java.math.BigInteger;

public class CreateWordNumberingsFormatted {

 static BigInteger getNewDecimalNumberingId(XWPFDocument document, BigInteger abstractNumID) {
  CTAbstractNum cTAbstractNum = CTAbstractNum.Factory.newInstance();
  cTAbstractNum.setAbstractNumId(abstractNumID);

  CTLvl cTLvl = cTAbstractNum.addNewLvl();
  cTLvl.addNewNumFmt().setVal(STNumberFormat.DECIMAL);
  cTLvl.addNewLvlText().setVal("%1.");
  cTLvl.addNewStart().setVal(BigInteger.valueOf(1));

  XWPFAbstractNum abstractNum = new XWPFAbstractNum(cTAbstractNum);

  XWPFNumbering numbering = document.createNumbering();

  abstractNumID = numbering.addAbstractNum(abstractNum);

  BigInteger numID = numbering.addNum(abstractNumID);

  return numID;
 }

 static void setParagraphRunProperties(XWPFParagraph paragraph, String fontFamily, int fontSize) {
  if (!paragraph.getCTP().isSetPPr()) paragraph.getCTP().addNewPPr();
  if (!paragraph.getCTP().getPPr().isSetRPr()) paragraph.getCTP().getPPr().addNewRPr();
  if (!paragraph.getCTP().getPPr().getRPr().isSetRFonts()) paragraph.getCTP().getPPr().getRPr().addNewRFonts();
  if (!paragraph.getCTP().getPPr().getRPr().isSetSz()) paragraph.getCTP().getPPr().getRPr().addNewSz();
  if (!paragraph.getCTP().getPPr().getRPr().isSetSzCs()) paragraph.getCTP().getPPr().getRPr().addNewSzCs();
  paragraph.getCTP().getPPr().getRPr().getRFonts().setAscii(fontFamily);
  paragraph.getCTP().getPPr().getRPr().getRFonts().setHAnsi(fontFamily);
  paragraph.getCTP().getPPr().getRPr().getSz().setVal(BigInteger.valueOf(fontSize*2)); //measurement unit is half pt
  paragraph.getCTP().getPPr().getRPr().getSzCs().setVal(BigInteger.valueOf(fontSize*2)); //measurement unit is half pt
 }


 public static void main(String[] args) throws Exception {

  XWPFDocument document = new XWPFDocument();

  XWPFParagraph paragraph = document.createParagraph();
  XWPFRun run = paragraph.createRun();  
  run.setText("The paragraph before first numbering:");

  int abstractNumID = 0;

  //get NumID for first decimal numbering
  BigInteger numID = getNewDecimalNumberingId(document, BigInteger.valueOf(abstractNumID++));

  //now apply that NumID to first list
  String fontFamily = "Times New Roman";
  int fontSize = 24;
  //first paragraph
  paragraph = document.createParagraph();
  //apply NumID
  paragraph.setNumID(numID);
  //set paragraph run properties
  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  //create text runs and format
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("One");
  //further numbered paragraphs
  paragraph = document.createParagraph();
  paragraph.setNumID(numID);
  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("Two");

  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("Three");

  paragraph = document.createParagraph();

  //get NumID forsecond decimal numbering
  numID = getNewDecimalNumberingId(document, BigInteger.valueOf(abstractNumID++));

  //now apply that NumID to second list having different font
  fontFamily = "Courier New";
  fontSize = 32;
  paragraph = document.createParagraph();
  paragraph.setNumID(numID);
  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("One");
  paragraph = document.createParagraph();
  paragraph.setNumID(numID);
  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("Two");
  paragraph = document.createParagraph();
  paragraph.setNumID(numID);
  setParagraphRunProperties(paragraph, fontFamily, fontSize);
  run = paragraph.createRun(); 
  run.setFontFamily(fontFamily); 
  run.setFontSize(fontSize); 
  run.setText("Three");

  paragraph = document.createParagraph();

  FileOutputStream out = new FileOutputStream("CreateWordNumberingsFormatted.docx");
  document.write(out);
  out.close();
  document.close();

 }
}

Answer 2

我正在使用 POI 5.2.3，并且在查找 getRPr 方法 isSetRFonts、isSetSz、isSetSzCs 以及上面答案中 setParagraphRunProperties 中相应的“gets”时遇到问题。

显然，自从 Axel 上面的回复以来，事情发生了变化，但我不知道在用谷歌搜索没有成功后该去哪里寻找。

任何帮助将不胜感激。
