我想从一个特定的段落内容的.DOCX复制到另一个空的.docx。问题我已经是我的风格，子弹从source.docx编号等不保留在目标.docx.Here是我的代码

谁能告诉我什么都改变被添加到上面的代码？ 提前致谢！！ 

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);

         }
             }

Answer 1:

我使用的“POI彬3.10.1-20140818”库从http://poi.apache.org/

您可以复制所有段落中.docx文件循环doc.getParagraphs（）。

但“表”是不是款，所以“表”是不可复制的。

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);

    }
}

于是复制了所有段落和表格代码如下所示。 

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);
    }
}

但是，即使通过这样的方式，你不能复制形象和风格。

所以复制的文档看起来与原始文件不同。

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

包括XWPFRun.addPicture添加图像文件DOCX（）不是由Microsoft Word中打开。

下面的代码，包括未来的功能。

1）复制段落和表格的内容和风格

2）复制的页面布局

3）从源的docx文件拷贝图像
