如何在poi word XWPF的首页和其他页面中生成不同的页眉? [英] How to generate different headers in first page and other pages in poi word XWPF?

问题描述

我想在poi word的首页和其他页面中生成不同的标题，因此我使用了XWPFHeaderFooterPolicy.FIRST和XWPFHeaderFooterPolicy.DEFAULT.当我使用XWPFHeaderFooterPolicy.DEFAULT时，我可以成功插入标头，但是当我更改为XWPFHeaderFooterPolicy.FIRST时，我在第一页中看不到标头，这是下面的代码，这是怎么了?谢谢！

I want to generate different headers in first page and other pages in poi word, So I used XWPFHeaderFooterPolicy.FIRST and XWPFHeaderFooterPolicy.DEFAULT. when I using XWPFHeaderFooterPolicy.DEFAULT I can insert my header successfully, but when I change to XWPFHeaderFooterPolicy.FIRST, I cannot see there is a header in my first page, this is my code in below, what's wrong with it? thanks!

XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.FIRST);
      paragraph = header.createParagraph();
      paragraph.setAlignment(ParagraphAlignment.LEFT);
      run = paragraph.createRun();  
      run.setText("header");

推荐答案

仅为首页设置了不同的标题，这意味着也不会显示此标题.在Word GUI中，在Header & Footer Tools中有一个复选框[x] Different First Page用于实现该目标.

That there is a different header set for first page only, means not that this header will also be shown. In Word GUI there is a checkbox [x] Different First Page in Header & Footer Tools to achieve that.

并且根据 Office Open XML Part 4-标记语言参考，必须设置一个布尔XML元素titlePg才能确定是否存在标题页.

And according Office Open XML Part 4 - Markup Language Reference there must a boolean XML element titlePg be set to determine that there is a title page present.

在实际的apache poi最终版本3.15中，只能使用doc.getDocument().getBody().getSectPr().addNewTitlePg();使用底层低级对象来设置此XML元素titlePg.

In actual final apache poi version 3.15 this XML element titlePg can only be set using underlying low level objects using doc.getDocument().getBody().getSectPr().addNewTitlePg();.

但是apache poi版本3.16 Beta 2具有doc.createHeader(HeaderFooterType.FIRST);，它在XML中设置了titlePg标志.

But apache poi version 3.16 Beta 2 has doc.createHeader(HeaderFooterType.FIRST); which sets titlePg flag in XML.

完整示例:

import java.io.*;

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

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

public class CreateWordHeaderFooterDifferent {

 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 first page header
  XWPFHeader header = doc.createHeader(HeaderFooterType.FIRST);

  paragraph = header.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.LEFT);

  run = paragraph.createRun();  
  run.setText("The first page header:");

  // create default page header
  header = doc.createHeader(HeaderFooterType.DEFAULT);

  paragraph = header.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.LEFT);

  run = paragraph.createRun();  
  run.setText("The default page header:");

  // create footer
  XWPFFooter footer = doc.createFooter(HeaderFooterType.DEFAULT);

  paragraph = footer.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.CENTER);

  run = paragraph.createRun();  
  run.setText("Page ");
  paragraph.getCTP().addNewFldSimple().setInstr("PAGE \\* MERGEFORMAT");
  run = paragraph.createRun();  
  run.setText(" of ");
  paragraph.getCTP().addNewFldSimple().setInstr("NUMPAGES \\* MERGEFORMAT");

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

 }
}

但是我认为在创建HeaderFooterType.FIRST时自动在XML中设置titlePg标志是不正确的.由于Word可以在[x] Different First Page和[] Different First Page之间切换，因此apache poi也应该可以.因此，设置titlePg标志应该是XWPFDocument中的一种方法.

But in my opinion the setting titlePg flag in XML automatically while HeaderFooterType.FIRST is created is not correct. Since Word can toggle between [x] Different First Page and [] Different First Page, apache poi should also be able to do so. So the setting the titlePg flag should be a method in XWPFDocument.
