如何通过poi设置单词中不同部分的页码

Question

我的文件有三个部分：封面，内容和文字。我想为每个部分设置不同的页码。封面不需要页码。内容页码以罗马数字表示，主体中的页面以希腊语编号。能用POI实现吗？

Answer 1

Apache poi - 直到现在 - 只创建三种类型的页眉/页脚：HeaderFooterType .DEFAULT，.EVEN和.First。

因此，为了满足您的要求，我们需要使用底层的低级对象。我们需要作弊才能创建不同的页脚。

我们需要两个不同的页脚。一个用于第2部分（内容），另一个用于第3部分（文本）。但两者都必须是DEFAULT类型。由于直到现在才使用apache poi这是不可能的，因此我们首先为整个文档创建两个不同类型的页脚（FIRST和DEFAULT）。然后我们将FIRST页脚更改为DEFAULT并将其移动为第2部分的页脚参考。

示例：

import java.io.FileOutputStream;

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

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTDocument1;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTBody;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSectPr;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTHdrFtrRef;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr;

public class CreateWordMultipleSectionPageNumbering {

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

  XWPFDocument document= new XWPFDocument();

  //create first footer for section 2 - first created as first footer for the document
  XWPFFooter footer = document.createFooter(HeaderFooterType.FIRST); 
  //making it HeaderFooterType.FIRST first to be able creating one more footer later
  //will changing this later to HeaderFooterType.DEFAULT

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

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

  //create second footer for section 3 == last section in document
  footer = document.createFooter(HeaderFooterType.DEFAULT);

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

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

  //create document content.

  //section 1
  paragraph = document.createParagraph();
  run=paragraph.createRun();  
  run.setText("Cover");

  //paragraph with section setting for section above
  paragraph = document.createParagraph();
  CTSectPr ctSectPr = paragraph.getCTP().addNewPPr().addNewSectPr();

  //section 2
  paragraph = document.createParagraph();
  run=paragraph.createRun();  
  run.setText("Contents");

  //paragraph with section setting for section above
  paragraph = document.createParagraph();
  CTSectPr ctSectPrSect2 = paragraph.getCTP().addNewPPr().addNewSectPr(); //we need this later

  //section 3 
  paragraph = document.createParagraph();
  run=paragraph.createRun();
  run.setText("Text");

  //section setting for section above == last section in document
  CTDocument1 ctDocument = document.getDocument();
  CTBody ctBody = ctDocument.getBody();
  CTSectPr ctSectPrLastSect = ctBody.getSectPr(); //there must be a SectPr already because of the footer settings above

  //get footer reference of first footer and move this to be footer reference for section 2
  CTHdrFtrRef ctHdrFtrRef = ctSectPrLastSect.getFooterReferenceArray(0);
  ctHdrFtrRef.setType(STHdrFtr.DEFAULT); //change this from STHdrFtr.FIRST to STHdrFtr.DEFAULT
  CTHdrFtrRef[] ctHdrFtrRefs = new CTHdrFtrRef[]{ctHdrFtrRef};
  ctSectPrSect2.setFooterReferenceArray(ctHdrFtrRefs);
  ctSectPrLastSect.removeFooterReference(0);

  //unset "there is a title page" for the whole document because we have a section for the title (cover)
  ctSectPrLastSect.unsetTitlePg();

  document.write(new FileOutputStream("CreateWordMultipleSectionPageNumbering.docx"));

 }
}

使用过的低级对象的参考：http://grepcode.com/snapshot/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/。

上面的代码显示了原理。如果需要满足进一步的要求，那么应该知道*.docx文件只是一个ZIP存档，可以解压缩并查看它。因此，可以使用Word创建满足要求的*.docx文件，然后解压缩并查看/word/document.xml。

例如： “如何设置罗马数字以I II开头，阿拉伯数字再次以1,2开头？”

如果在Word create a Word document that uses different page numbering formats。然后在/word/document.xml中你会发现类似的内容：

...
 <w:sectPr>
  ...
  <w:pgNumType w:start="1"/>
  ...
 </w:sectPr>
...

因此，我们需要PgNumType中的XML元素。

再次完成示例：

import java.io.FileOutputStream;

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

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTDocument1;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTHdrFtrRef;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr;

public class CreateWordMultipleSectionPageNumbering {

 //default section setting for page size and page borders
 //measurement unit = twips (twentieth of an inch point) = 1 inch = 1440 twips
 private static String defaultSectPr = 
   "<w:sectPr xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\">"
  +"<w:pgSz w:w=\"12240\" w:h=\"15840\"/>" //A4
  +"<w:pgMar w:top=\"1417\" w:right=\"1417\" w:bottom=\"1134\" w:left=\"1417\""
  +" w:header=\"720\" w:footer=\"720\" w:gutter=\"0\"/>"
  +"<w:cols w:space=\"720\"/>"
  +"</w:sectPr>"; 

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

  CTSectPr ctSectPrDefault = (CTPPr.Factory.parse(defaultSectPr)).getSectPr();

  XWPFDocument document= new XWPFDocument();

  //set the default section setting for page size and page borders 
  CTDocument1 ctDocument = document.getDocument();
  CTBody ctBody = ctDocument.getBody();
  ctBody.setSectPr(ctSectPrDefault);

  //create first footer for section 2 - first created as first footer for the document
  XWPFFooter footer = document.createFooter(HeaderFooterType.FIRST); 
  //making it HeaderFooterType.FIRST first to be able creating one more footer later
  //will changing this later to HeaderFooterType.DEFAULT

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

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

  //create second footer for section 3 == last section in document
  footer = document.createFooter(HeaderFooterType.DEFAULT);

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

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

  //create document content.

  //section 1
  paragraph = document.createParagraph();
  run=paragraph.createRun();  
  run.setText("Cover");

  //paragraph with section setting for section above
  paragraph = document.createParagraph();
  paragraph.getCTP().addNewPPr().setSectPr(ctSectPrDefault);

  //section 2
  paragraph = document.createParagraph();
  run=paragraph.createRun();  
  run.setText("Contents");
  paragraph = document.createParagraph();
  run = paragraph.createRun();
  run.setText("Lorem ipsum semit dolor ...");
  run.addBreak(BreakType.PAGE); 
  paragraph = document.createParagraph();

  //paragraph with section setting for section above
  paragraph = document.createParagraph();
  paragraph.getCTP().addNewPPr().setSectPr(ctSectPrDefault);  
  CTSectPr ctSectPrSect2 = paragraph.getCTP().getPPr().getSectPr(); //we need this later
  //set this page numbering starting with 1 again
  ctSectPrSect2.addNewPgNumType().setStart(java.math.BigInteger.valueOf(1));

  //section 3 
  paragraph = document.createParagraph();
  run=paragraph.createRun();
  run.setText("Text");
  paragraph = document.createParagraph();
  run = paragraph.createRun();
  run.setText("Lorem ipsum semit dolor ...");
  run.addBreak(BreakType.PAGE); 
  paragraph = document.createParagraph();

  //section setting for section above == last section in document
  CTSectPr ctSectPrLastSect = ctBody.getSectPr(); 
  //there must be a SectPr already because of the default and footer settings above
  //set this page numbering starting with 1 again
  ctSectPrLastSect.addNewPgNumType().setStart(java.math.BigInteger.valueOf(1));

  //get footer reference of first footer and move this to be footer reference for section 2
  CTHdrFtrRef ctHdrFtrRef = ctSectPrLastSect.getFooterReferenceArray(0);
  ctHdrFtrRef.setType(STHdrFtr.DEFAULT); //change this from STHdrFtr.FIRST to STHdrFtr.DEFAULT
  CTHdrFtrRef[] ctHdrFtrRefs = new CTHdrFtrRef[]{ctHdrFtrRef};
  ctSectPrSect2.setFooterReferenceArray(ctHdrFtrRefs);
  ctSectPrLastSect.removeFooterReference(0);

  //unset "there is a title page" for the whole document because we have a section for the title (cover)
  ctSectPrLastSect.unsetTitlePg();

  document.write(new FileOutputStream("CreateWordMultipleSectionPageNumbering.docx"));

 }
}

这也使用SECTIONPAGES Word内NUMPAGES字段中的*.docx字段，仅对单个部分中的页面进行编号，而不是整个文档页面。

此外，它还在每个部分中使用页面大小和页面边框的默认部分设置。这与可以读取pip install -t lib -r requirements.txt 个文件的不同文字处理应用程序更兼容。
