如何将.docx的段落复制到另一个.docx withJava并保留样式
我试图将内容从.docx中的特定段落复制到另一个空的.docx。我遇到的问题是来自source.docx的样式，项目符号，编号等不会保留在目标.docx.Here是我的代码
任何人都可以告诉我上面的代码中添加了哪些更改？ 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); } } 我在http://poi.apache.org/上使用“poi-bin-3.10.1-20140818”库
您可以复制循环doc.getParagraphs（）的.docx文件中的所有段落。
但“表”不是段落，因此不会复制“表”。
要复制“Table”，您必须获取IBodyElement并循环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); } }
所以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); } }
但即便通过这种方式，你也无法复制图像和风格。
因此复制的文档与原始文档看起来不同。
似乎org.apache.poi.xwpf.usermodel.XWPFRun.addPicture（）方法有bug。
Microsoft Word不会打开包含由XWPFRun.addPicture（）添加的图像的Docx文档。

下面的代码包括下一个function。
1）复制段落和表格的内容和样式
2）复制页面布局
3）从源docx文件复制图像
