本文介绍了如何用Java将一段.docx复制到另一个.docx并保留样式的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将 .docx 中特定段落的内容复制到另一个空的 .docx.我遇到的问题是 source.docx 中的样式、项目符号、编号等未保留在目标 .docx 中.这是我的代码
I am trying to copy the content from a particular paragraph in a .docx to another empty .docx .the problem i have is that the style,bullets,numbering etc from the source.docx is not retained in the destination .docx.Here is my code
谁能告诉我要添加到上述代码中的更改是什么?提前致谢！！
can anyone please tell me what are the changes to be added to the above code? Thanks in Advance!!
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);
}
}
推荐答案
我正在使用poi-bin-3.10.1-20140818"来自 http://poi.apache.org/
I'm using "poi-bin-3.10.1-20140818" library from http://poi.apache.org/
您可以复制.docx文件中的所有段落循环doc.getParagraphs()
You can copy all paragraphs in the .docx file looping doc.getParagraphs()
但是Table不是段落，所以Table不会被复制.
But Table is not paragraph, so Table is not copied.
要复制Table，您必须获取IBodyElement 并循环doc.getBodyElements().
To copy Table, you have to get IBodyElement and looping 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);
}
}
所以复制所有段落和表格的代码如下所示.
So the code that copy all paragraphs and tables is like below.
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，您也无法复制图像和样式.
But even through this way, you can't copy image and style.
所以复制的文件和原文件看起来不一样.
So copied document looks different with original document.
看来 org.apache.poi.xwpf.usermodel.XWPFRun.addPicture() 方法有问题.
包含由 XWPFRun.addPicture() 添加的图像的 Docx 文档无法通过 Microsoft Word 打开.
Docx document including image added by XWPFRun.addPicture() is not opened by Microsoft Word.

下面的代码包括下一个功能.
Below code is including next functionality.
复制段落和表格的内容和样式
copy contents and styles of paragraphs and tables
复制页面布局
从源 docx 文件复制图像
