(Java)如何使用彩色文本写入RTF文件

import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.CharacterRun;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.hwpf.usermodel.Section;

POIFSFileSystem fs = new POIFSFileSystem();
HWPFDocument doc = new HWPFDocument(fs);

Range range = doc.getRange();

Paragraph paragraph = range.insertAfter(new Paragraph());

CharacterRun run = paragraph.createRun();
run.setText("彩色文本");
run.setColor(255, 0, 0); // 设置文本颜色为红色

doc.write(new FileOutputStream("output.rtf"));
doc.close();
