两个docx文档，1.docx和2.docx，需要将1.docx文档中的页眉页脚同步到2.docx，用java编写，使用开源jar包，比如poi，poi-tl，docx4j等等，麻烦给我源码

### 回答1：

我可以提供一些参考示例代码，但并不能保证其完全可行。首先，使用POI获取1.docx文档中的页眉内容：HWPFDocument document1 = new HWPFDocument(new FileInputStream("1.docx"));
HeaderStories headerStories = document1.getHeaderStories();
String headerText = headerStories.getFirstHeader();然后，使用POI-TL更新2.docx文档的页眉：HWPFDocument document2 = new HWPFDocument(new FileInputStream("2.docx"));
HeaderStories headerStories2 = document2.getHeaderStories();
headerStories2.setHeader(headerText);最后，使用POI将更新后的2.docx文档输出到磁盘：document2.write(new FileOutputStream("2.docx"));

使用poi和poi-tl来实现将一个docx文档中的页眉页脚同步到另一个docx文档的源码如下：

import org.apache.poi.xwpf.usermodel.*;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class DocxHeaderFooterSync {
    public static void main(String[] args) {
        String sourceFilePath = "1.docx";
        String targetFilePath = "2.docx";

        try {
            FileInputStream sourceFileInputStream = new FileInputStream(sourceFilePath);
            FileInputStream targetFileInputStream = new FileInputStream(targetFilePath);

            XWPFDocument sourceDocument = new XWPFDocument(sourceFileInputStream);
            XWPFDocument targetDocument = new XWPFDocument(targetFileInputStream);

            copyHeaderFooter(sourceDocument, targetDocument);

            FileOutputStream fileOutputStream = new FileOutputStream(targetFilePath);
            targetDocument.write(fileOutputStream);

            fileOutputStream.close();
            sourceFileInputStream.close();
            targetFileInputStream.close();

            System.out.println("页眉页脚同步成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static void copyHeaderFooter(XWPFDocument sourceDocument, XWPFDocument targetDocument) {
        XWPFHeaderFooterPolicy sourceHeaderFooterPolicy = sourceDocument.getHeaderFooterPolicy();
        if (sourceHeaderFooterPolicy != null) {
            XWPFHeader sourceHeader = sourceHeaderFooterPolicy.getDefaultHeader();
            XWPFFooter sourceFooter = sourceHeaderFooterPolicy.getDefaultFooter();

            XWPFHeaderFooterPolicy targetHeaderFooterPolicy = targetDocument.getHeaderFooterPolicy();
            if (targetHeaderFooterPolicy != null) {
                XWPFHeader targetHeader = targetHeaderFooterPolicy.getDefaultHeader();
                XWPFFooter targetFooter = targetHeaderFooterPolicy.getDefaultFooter();

                if (sourceHeader != null && targetHeader != null) {
                    targetHeader.getParagraphs().clear();
                    for (XWPFParagraph paragraph : sourceHeader.getParagraphs()) {
                        XWPFParagraph targetParagraph = targetHeader.createParagraph();
                        targetParagraph.getCTP().set(paragraph.getCTP());
                    }
                }

                if (sourceFooter != null && targetFooter != null) {
                    targetFooter.getParagraphs().clear();
                    for (XWPFParagraph paragraph : sourceFooter.getParagraphs()) {
                        XWPFParagraph targetParagraph = targetFooter.createParagraph();
                        targetParagraph.getCTP().set(paragraph.getCTP());
                    }
                }
            }
        }
    }
}

请注意，运行此代码之前，请确保已经添加了相应的poi和poi-tl的jar包依赖。此代码会将1.docx文档中的默认页眉页脚同步到2.docx文档的默认页眉页脚。如需同步其他类型的页眉页脚，请根据需要进行相应修改。

import org.apache.poi.xwpf.usermodel.*;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class SyncHeaderFooter {

public static void main(String[] args) {
String sourceFilePath = "1.docx";
String targetFilePath = "2.docx";

try {
XWPFDocument sourceDoc = new XWPFDocument(new FileInputStream(sourceFilePath));
XWPFDocument targetDoc = new XWPFDocument(new FileInputStream(targetFilePath));

// 获取源文档的页眉
XWPFHeader sourceHeader = sourceDoc.getHeaderList().get(0);
// 获取源文档的页脚
XWPFFooter sourceFooter = sourceDoc.getFooterList().get(0);

// 获取目标文档的所有页
for (XWPFHeaderFooterPolicy hfp : targetDoc.getHeaderFooterPolicy()) {
// 设置目标文档的页眉和页脚为源文档的页眉和页脚
hfp.setDefaultHeader(sourceHeader);
hfp.setDefaultFooter(sourceFooter);
}

// 保存目标文档
FileOutputStream outputStream = new FileOutputStream(targetFilePath);
targetDoc.write(outputStream);
outputStream.close();

System.out.println("页眉页脚同步完成");
} catch (IOException e) {
e.printStackTrace();
}
}
}
