使用java poi 将一份docx文件的内容,格式,表格,图片复制到另一个docx文件的代码

由于Java POI库并不支持直接复制docx文件的内容、格式、表格、图片等,因此需要借助其他的库或者手动实现复制的逻辑。以下是一种可能的实现方案:
1. 使用Apache Tika库解析原始docx文件,并获取其中文本、表格、图片等信息。代码示例:
```
InputStream is = new FileInputStream("source.docx");
ContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
ParseContext context = new ParseContext();
AutoDetectParser parser = new AutoDetectParser();
parser.parse(is, handler, metadata, context);
String text = handler.toString();
List<XWPFTable> tables = new XWPFDocument(is).getTables();
List<XWPFPictureData> pictures = new XWPFDocument(is).getAllPictures();
```
2. 创建一个新的XWPFDocument对象,并将上一步获取到的信息逐一添加到其中。代码示例:
```
XWPFDocument newDoc = new XWPFDocument();
XWPFParagraph para = newDoc.createParagraph();
para.createRun().setText(text);
for (XWPFTable table : tables) {
newDoc.createTable(table);
}
for (XWPFPictureData picture : pictures) {
byte[] bytes = picture.getData();
int type = picture.getPictureType();
String filename = picture.getFileName();
int id = newDoc.getNextPicNameNumber(type);
newDoc.addPictureData(bytes, type);
newDoc.createPicture(id, newDoc.getNextPicNameNumber(type), 1024, 768, filename);
}
```
3. 将新的XWPFDocument对象保存到目标docx文件中。代码示例:
```
FileOutputStream fos = new FileOutputStream("target.docx");
newDoc.write(fos);
fos.close();
```
完整代码如下:
```
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.*;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.List;
public class CopyDocx {
public static void main(String[] args) throws Exception {
InputStream is = new FileInputStream("source.docx");
ContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
ParseContext context = new ParseContext();
AutoDetectParser parser = new AutoDetectParser();
parser.parse(is, handler, metadata, context);
String text = handler.toString();
List<XWPFTable> tables = new XWPFDocument(is).getTables();
List<XWPFPictureData> pictures = new XWPFDocument(is).getAllPictures();
XWPFDocument newDoc = new XWPFDocument();
XWPFParagraph para = newDoc.createParagraph();
para.createRun().setText(text);
for (XWPFTable table : tables) {
newDoc.createTable(table);
}
for (XWPFPictureData picture : pictures) {
byte[] bytes = picture.getData();
int type = picture.getPictureType();
String filename = picture.getFileName();
int id = newDoc.getNextPicNameNumber(type);
newDoc.addPictureData(bytes, type);
newDoc.createPicture(id, newDoc.getNextPicNameNumber(type), 1024, 768, filename);
}
FileOutputStream fos = new FileOutputStream("target.docx");
newDoc.write(fos);
fos.close();
}
}
```
