使用Java:替换MS Word文件中的字符串

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

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

public class WordReplace {
    public static void main(String[] args) throws IOException {
        File file = new File("input.docx");
        FileInputStream fis = new FileInputStream(file.getAbsolutePath());
        XWPFDocument document = new XWPFDocument(fis);

        for (XWPFParagraph paragraph : document.getParagraphs()) {
            for (XWPFRun run : paragraph.getRuns()) {
                String text = run.getText(0);
                if (text != null && text.contains("旧文本")) {
                    run.setText("新文本", 0);
                }
            }
        }

        FileOutputStream fos = new FileOutputStream("output.docx");
        document.write(fos);
        fos.close();
        document.close();
    }
}
