如何将一段.docx复制到另一个.docx withJava并保留样式

我想将.docx中的特定段落的内容复制到另一个空的.docx中。我遇到的问题是样式，子目录，编号等从源码.docx不会保留在目标.docx.Here是我的代码如何将一段.docx复制到另一个.docx withJava并保留样式

任何人都可以请告诉我什么是要添加到上述代码的更改？在此先感谢！

public class WordFinal { 

     public static void main(String[] args) throws IOException, XmlException { 

     XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx")); 

     XWPFDocument destDoc =new XWPFDocument(); 

     OutputStream out = new FileOutputStream("Destination.docx"); 

     XWPFParagraph pr =doc.getParagraphs()[1]; 

     String copy=pr.getText(); 

     XWPFParagraph paragraphOne = destDoc.createParagraph(); 

     XWPFRun paragraphOneRunOne = paragraphOne.createRun(); 

     paragraphOneRunOne.setText(copy); 

     destDoc.write(out); 

     } 
      }

你应该用库标记你的问题来解析你正在使用的docx，这样它会吸引更多的人知道它是如何工作的。 – 2012-04-18 11:29:42

您需要从样式部分复制相关样式，并从编号部分编号。对于POI和docx4j，你如何做到这一点会有所不同。 – JasonPlutext 2012-04-22 16:17:47

可以请你解释我应该如何从样式部分复制样式以及示例代码？ – Dharmin 2012-04-23 04:42:21

我使用的是从http://poi.apache.org/

“POI彬3.10.1-20140818” 库您可以复制在.docx文件循环doc.getParagraphs（）所有段落。

但“Table”不是段落，所以“Table”不会被复制。

要复制 “表”，你必须得到IBodyElement和循环doc.getBodyElements（）。

import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.OutputStream; 

import org.apache.poi.xwpf.usermodel.XWPFDocument; 
import org.apache.poi.xwpf.usermodel.XWPFParagraph; 
import org.apache.xmlbeans.XmlException; 

public class WordFinal { 

    public static void main(String[] args) throws IOException, XmlException { 

     XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx")); 

     XWPFDocument destDoc = new XWPFDocument(); 

     OutputStream out = new FileOutputStream("Destination.docx"); 

     // ** This code will copy just one paragraph. ** 

     XWPFParagraph pr = doc.getParagraphs().get(0); 

     destDoc.createParagraph(); 

     int pos = destDoc.getParagraphs().size() - 1; 

     destDoc.setParagraph(pr, pos); 

     destDoc.write(out); 

    } 
}

因此，复制所有段落和表格的代码如下所示。

import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.OutputStream; 

import org.apache.poi.xwpf.usermodel.BodyElementType; 
import org.apache.poi.xwpf.usermodel.IBodyElement; 
import org.apache.poi.xwpf.usermodel.XWPFDocument; 
import org.apache.poi.xwpf.usermodel.XWPFParagraph; 
import org.apache.poi.xwpf.usermodel.XWPFTable; 
import org.apache.xmlbeans.XmlException; 

public class WordFinal { 

    public static void main(String[] args) throws IOException, XmlException { 

     XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx")); 

     XWPFDocument destDoc = new XWPFDocument(); 

     OutputStream out = new FileOutputStream("Destination.docx"); 

     for (IBodyElement bodyElement : doc.getBodyElements()) { 

      BodyElementType elementType = bodyElement.getElementType(); 

      if (elementType.name().equals("PARAGRAPH")) { 

       XWPFParagraph pr = (XWPFParagraph) bodyElement; 

       destDoc.createParagraph(); 

       int pos = destDoc.getParagraphs().size() - 1; 

       destDoc.setParagraph(pr, pos); 

      } else if(elementType.name().equals("TABLE")) { 

       XWPFTable table = (XWPFTable) bodyElement; 

       destDoc.createTable(); 

       int pos = destDoc.getTables().size() - 1; 

       destDoc.setTable(pos, table); 
      } 
     } 

     destDoc.write(out); 
    } 
}

但即使通过这种方式，你也无法复制图像和样式。

如此复制的文档与原始文档看起来不同。

看来，org.apache.poi.xwpf.usermodel.XWPFRun.addPicture（）方法有bug。

包含由XWPFRun.addPicture（）添加的图像的Docx文档不由Microsoft Word打开。

下面代码包括下一个功能。

1）复制内容和样式的段落和表

2）复制的页面布局

3）从源的docx文件
