如何使用Apache POI从.docx文件中检索水印文本？

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.List;

public class DocxReader {
    public static void main(String[] args) {
        try {
            // 加载 .docx 文件
            File file = new File("path/to/your/document.docx");
            FileInputStream fis = new FileInputStream(file);
            XWPFDocument document = new XWPFDocument(fis);

            // 获取文档中的所有段落
            List<XWPFParagraph> paragraphs = document.getParagraphs();

            // 遍历并打印每个段落的文本
            for (XWPFParagraph paragraph : paragraphs) {
                System.out.println(paragraph.getText());
            }

            // 关闭文档
            fis.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
