java - 使用JAVA写入word文件

Question

我读了一个 word 文档，想用 Java 写入另一个 word 文件。我希望读取文档中的内容的样式(字体、粗体、斜体、标题等)被写入，因为它是创建的新文档。我可以复制内容，但不能复制格式样式。

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import java.util.List;

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

        XWPFDocument docx = new XWPFDocument(new  FileInputStream("d:\\Profiles\\mehjain\\Desktop\\Test1.docx"));
        List<XWPFParagraph> paragraphList =  docx.getParagraphs();

        XWPFDocument document= new XWPFDocument(); 
        FileOutputStream out = new FileOutputStream(new File("d:\\Profiles\\mehjain\\Desktop\\Test2.docx"));
        XWPFParagraph n = document.createParagraph();
        XWPFRun run=n.createRun();

        for (XWPFParagraph paragraph: paragraphList)
        { 
            run.setText(paragraph.getText());              
            run.addCarriageReturn();
        }
        document.write(out); 
        document.close();   
        out.close();
        System.out.println("Test2.docx written successfully");
    }
}

我得到了复制相同格式文本的答案，但我无法复制数字。我执行了这段代码:

 import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.IBody;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.hwpf.model.StyleDescription;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFStyle;
import org.apache.poi.xwpf.usermodel.XWPFStyles;
import java.util.List;

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

  XWPFDocument docx = new XWPFDocument(new    FileInputStream("d:\\Profiles\\mehjain\\Desktop\\Test1.docx"));

  List<XWPFParagraph> paragraphList =  docx.getParagraphs();

   XWPFDocument document= new XWPFDocument(); 
   FileOutputStream out = new FileOutputStream(new File("d:\\Profiles\\mehjain\\Desktop\\Test2.docx"));
   XWPFParagraph n = document.createParagraph();



  for (XWPFParagraph paragraph : paragraphList)
  {

       for(XWPFRun run1 : paragraph.getRuns())
       {
         XWPFRun run=n.createRun();
         run.setText(run1.getText(0));
        run.setFontFamily( run1.getFontFamily() );
        run.setBold( run1.isBold() );
        run.setItalic( run1.isItalic() );
        run.setStrike( run1.isStrike() );
        run.setColor( run1.getColor() );
        }
       XWPFRun run=n.createRun();
       run.addCarriageReturn();
    }
   document.write(out); 
   document.close();   
   out.close();
   System.out.println("Test2.docx written successfully"); 
  }
  }

将整个段落从一个 Word docx 复制到另一个文档比将所有内容从一个 Word docx 复制到另一个文档的单个段落中的单个运行要简单。并且由于您声明源 docx 中有编号，因此需要整个段落，因为只能对段落进行编号。

但是要复制编号，还必须复制 /word/numbering.xml。所以如果 Test1.docx 看起来像这样:

处理以下程序后:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;

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

import java.util.List;
import java.lang.reflect.Field;

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

  XWPFDocument docx1 = new XWPFDocument(new  FileInputStream("Test1.docx"));
  XWPFNumbering numberingDocx1 = docx1.getNumbering();
  // get paragraphListDocx1 as a List of all paragraphs from docx1
  List<XWPFParagraph> paragraphListDocx1 =  docx1.getParagraphs();

  // get the numbering.xml from docx1 to docx2
  // this is needed if some of the paragraphs from docx1 are numbered
  XWPFDocument docx2= new XWPFDocument(); 
  if (numberingDocx1 != null) {
   XWPFNumbering numberingDocx2 = docx2.createNumbering();
   try {
    Field f = numberingDocx1.getClass().getDeclaredField("ctNumbering");
    f.setAccessible(true);
    numberingDocx2.setNumbering((CTNumbering)f.get(numberingDocx1));
   } catch (NoSuchFieldException nsfex) {
   } catch (IllegalAccessException iaex) {
   }
  }

  // create a paragraph in docx2
  XWPFParagraph paragraphDocx2 = docx2.createParagraph();
  XWPFRun run = paragraphDocx2.createRun();
  run.setText("This is from Test1.docx:");

  // this will copy all paragraphs from paragraphListDocx1 to docx2
  for (XWPFParagraph paragraphDocx1 : paragraphListDocx1) { 
   paragraphDocx2 = docx2.createParagraph();
   docx2.setParagraph(paragraphDocx1, docx2.getPosOfParagraph(paragraphDocx2));            
  }

  paragraphDocx2 = docx2.createParagraph();
  run = paragraphDocx2.createRun();
  run.setText("^-- this was from Test1.docx.");


  FileOutputStream out = new FileOutputStream(new File("Test2.docx"));
  docx2.write(out); 
  docx2.close();   

  System.out.println("Test2.docx written successfully");
 }
}

Test2.docx 将如下所示:

注意:不会复制表格，因为我们只复制段落。由于 /word/media/*.* 未被复制，图片将被破坏。由于我们不复制 /word/styles.xml，因此不会复制像“标题 1”这样的特殊样式。
