java实现复制Word文档的部分内容到另一文档，文档中包含图片、图表等

要实现复制Word文档的部分内容到另一文档，包括图片、图表等，可以使用Java中的Apache POI库来操作Word文档。下面是一个简单的示例代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;

public class CopyWordDoc {
    public static void main(String[] args) {
        try {
            // 打开源文档
            FileInputStream fis = new FileInputStream(new File("source.docx"));
            XWPFDocument srcDoc = new XWPFDocument(fis);

            // 打开目标文档
            FileInputStream fis2 = new FileInputStream(new File("target.docx"));
            XWPFDocument targetDoc = new XWPFDocument(fis2);

            // 复制源文档中的所有元素到目标文档
            for (IBodyElement element : srcDoc.getBodyElements()) {
                if (element instanceof XWPFParagraph) {
                    // 如果是段落，复制段落
                    XWPFParagraph srcPara = (XWPFParagraph) element;
                    XWPFParagraph targetPara = targetDoc.createParagraph();
                    targetPara.createRun().setText(srcPara.getText());
                } else if (element instanceof XWPFTable) {
                    // 如果是表格，复制表格
                    XWPFTable srcTable = (XWPFTable) element;
                    XWPFTable targetTable = targetDoc.createTable();
                    targetTable.getCTTbl().setTblPr(srcTable.getCTTbl().getTblPr());
                    for (int i = 0; i < srcTable.getRows().size(); i++) {
                        XWPFTableRow srcRow = srcTable.getRow(i);
                        XWPFTableRow targetRow = targetTable.createRow();
                        for (int j = 0; j < srcRow.getTableCells().size(); j++) {
                            XWPFTableCell srcCell = srcRow.getCell(j);
                            XWPFTableCell targetCell = targetRow.getCell(j);
                            targetCell.getCTTc().setTcPr(srcCell.getCTTc().getTcPr());
                            for (IBodyElement cellElement : srcCell.getBodyElements()) {
                                if (cellElement instanceof XWPFParagraph) {
                                    // 如果是段落，复制段落
                                    XWPFParagraph srcPara = (XWPFParagraph) cellElement;

                                    targetPara.getCTP().setPPr(srcPara.getCTP().getPPr());
                                    targetPara.createRun().setText(srcPara.getText());
                                } else if (cellElement instanceof XWPFTable) {
                                    // 如果是表格，复制表格
                                    XWPFTable srcInnerTable = (XWPFTable) cellElement;

                    // 如果是图片，复制图片
                    XWPFPicture srcPicture = (XWPFPicture) element;
                    String blipId = srcPicture.getCTPicture().getBlipFill().getBlip().getEmbed();
                    byte[] imageData = srcDoc.getPackagePart().getPart(blipId).getBytes();
                    int pictureType = srcPicture.getPictureData().getPictureType();

                }
            }

            // 保存目标文档
            FileOutputStream fos = new FileOutputStream(new File("target.docx"));
            targetDoc.write(fos);

            // 关闭所有文件流
            fos.close();
            fis2.close();
            fis.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

该示例代码会打开名为`source.docx`的源文档和名为`target.docx`的目标文档，然后将源文档中的所有元素（包括段落、表格、文本框、图片等）复制到目标文档中，最后保存目标文档。你可以根据需要修改代码以满足你的实际需求。
