Apache POI -如何为XWPFRun设置字符间距

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

public class SetCharacterSpacingExample {
    public static void main(String[] args) throws Exception {
        // 创建一个新的Word文档
        XWPFDocument document = new XWPFDocument();

        // 创建一个段落
        XWPFParagraph paragraph = document.createParagraph();

        // 创建一个运行
        XWPFRun run = paragraph.createRun();
        run.setText("Hello, World!");

        // 设置字符间距为-10
        run.setCharacterSpacing(-10);

        // 保存文档
        document.write(new FileOutputStream("example.docx"));
        document.close();
    }
}
