使用docx4j生成pdf时，宋体(中文正文)类型无法转换成功。如何配置支持宋体(中文正文)类型字体？

转换结果为：

代码：

String tempPath = "G:\\TestDoc\\weituo2.docx";

WordprocessingMLPackage wordMLPackage = DocxUtils.getWordMLPackage(tempPath);

String outpath = "G:\\TestDoc\\业务委托单.pdf";

DocxUtils.toPDF(wordMLPackage,outpath);

public static void toPDF(WordprocessingMLPackage wordMLPackage,String outPath) throws Exception{

// Mapper fontMapper = new IdentityPlusMapper();

Mapper fontMapper = new IdentityPlusMapper();

wordMLPackage.setFontMapper(fontMapper);

// PhysicalFont font = PhysicalFonts.getPhysicalFonts().get("Arial Unicode MS");

// if (font!=null) {

// fontMapper.getFontMappings().put("Times New Roman", font);

// }

fontMapper.put("隶书", PhysicalFonts.get("LiSu"));

fontMapper.put("宋体",PhysicalFonts.get("SimSun"));

fontMapper.put("微软雅黑",PhysicalFonts.get("Microsoft Yahei"));

fontMapper.put("黑体",PhysicalFonts.get("SimHei"));

fontMapper.put("楷体",PhysicalFonts.get("KaiTi"));

fontMapper.put("新宋体",PhysicalFonts.get("NSimSun"));

fontMapper.put("华文行楷", PhysicalFonts.get("STXingkai"));

fontMapper.put("华文仿宋", PhysicalFonts.get("STFangsong"));

fontMapper.put("宋体扩展",PhysicalFonts.get("simsun-extB"));

fontMapper.put("仿宋",PhysicalFonts.get("FangSong"));

fontMapper.put("仿宋_GB2312",PhysicalFonts.get("FangSong_GB2312"));

fontMapper.put("幼圆",PhysicalFonts.get("YouYuan"));

fontMapper.put("华文宋体",PhysicalFonts.get("STSong"));

fontMapper.put("华文中宋",PhysicalFonts.get("STZhongsong"));

DocxUtils.toP(wordMLPackage,outPath);

}

public static void toP(WordprocessingMLPackage wordMLPackage,String outPath) throws Exception{

OutputStream os = new FileOutputStream(outPath);

FOSettings foSettings = Docx4J.createFOSettings();

foSettings.setWmlPackage(wordMLPackage);

Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);

}
