Java ApachePOI：如何设置字段的字体样式（页面、PAGENUM、PAGEREF…）

从另一个（已回答的）问题中，我学会了如何在Word文档中添加页面计数器。此外，我需要在字段（即页面计数器）上设置字体系列样式（颜色、粗体、斜体、下划线…）。如何做到这一点

CTSimpleField ctSimpleField = paragraph.getCTP().addNewFldSimple();

CTSimpleField不提供直接设置这些属性的方法

为了能够格式化，我们需要在

Word

中运行。但要使用运行创建字段，我们需要为每个字段运行三次。一次运行以标记

FldChar

开始，然后一次运行以标记字段

InstrText

，第三次运行以标记

FldChar

结束。每次运行都可以，但也必须根据需要进行格式化

例如：

import java.io.*;

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

import org.apache.poi.xwpf.model.XWPFHeaderFooterPolicy;

public class CreateWordHeaderFooter {

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

  XWPFDocument doc= new XWPFDocument();

  // the body content
  XWPFParagraph paragraph = doc.createParagraph();
  XWPFRun run=paragraph.createRun();  
  run.setText("The Body:");

  paragraph = doc.createParagraph();
  run=paragraph.createRun();  
  run.setText("Lorem ipsum.... page 1");

  paragraph = doc.createParagraph();
  run=paragraph.createRun();
  run.addBreak(BreakType.PAGE); 
  run.setText("Lorem ipsum.... page 2");

  paragraph = doc.createParagraph();
  run=paragraph.createRun();
  run.addBreak(BreakType.PAGE); 
  run.setText("Lorem ipsum.... page 3");

  // create header-footer
  XWPFHeaderFooterPolicy headerFooterPolicy = doc.getHeaderFooterPolicy();
  if (headerFooterPolicy == null) headerFooterPolicy = doc.createHeaderFooterPolicy();

  // create header start
  XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);

  paragraph = header.getParagraphArray(0);
  if (paragraph == null) paragraph = header.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.LEFT);

  run = paragraph.createRun();  
  run.setText("The Header:");

  // create footer start
  XWPFFooter footer = headerFooterPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);

  paragraph = footer.getParagraphArray(0);
  if (paragraph == null) paragraph = footer.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.CENTER);

  run = paragraph.createRun();
  run.setBold(true);  
  run.setText("Page ");

  run = paragraph.createRun();  
  run.setBold(true); 
  run.getCTR().addNewFldChar().setFldCharType(org.openxmlformats.schemas.wordprocessingml.x2006.main.STFldCharType.BEGIN);

  run = paragraph.createRun(); 
  run.setBold(true); 
  run.getCTR().addNewInstrText().setStringValue("PAGE \\* MERGEFORMAT");

  run = paragraph.createRun();  
  run.setBold(true); 
  run.getCTR().addNewFldChar().setFldCharType(org.openxmlformats.schemas.wordprocessingml.x2006.main.STFldCharType.END);

  run = paragraph.createRun();  
  run.setBold(true); 
  run.setText(" of ");

  run = paragraph.createRun();  
  run.setBold(true); 
  run.getCTR().addNewFldChar().setFldCharType(org.openxmlformats.schemas.wordprocessingml.x2006.main.STFldCharType.BEGIN);

  run = paragraph.createRun();  
  run.setBold(true); 
  run.getCTR().addNewInstrText().setStringValue("NUMPAGES \\* MERGEFORMAT");

  run = paragraph.createRun();  
  run.setBold(true); 
  run.getCTR().addNewFldChar().setFldCharType(org.openxmlformats.schemas.wordprocessingml.x2006.main.STFldCharType.END);

  doc.write(new FileOutputStream("CreateWordHeaderFooter.docx"));

格式化“第x页，共y页”仅格式化“第”页和“共”页，而不格式化x页或y页。
XWPFRun=paragration.createRun（）；run.setText（“页面”）；run.setBold（true）；run.setFontFamily（“Arial”）；格式化“第x页，共y页”仅格式化“第”页和“共”页，而不格式化x页或y页。
