IText导出pdf不显示泰文

使用IText导出PDF意外发现其他外文都能导出成功，只有泰文会消失，查了一下没有能用的办法，官网也没有我这种情况，最后还是误打误撞试出来的。还是要下载泰文字体，网上很多，我是从这里下载的：https://fontmeme.com/ziti/thai-fonts/

导出pdf的方法，使用的是html当模版，重要的是getConverterProperties方法。

	//生成PDF文件至文件服务器private BaseFileInfoResp uploadPdfToFileServer(PoInfo poInfo) {try (ByteArrayOutputStream output = new ByteArrayOutputStream()) {Map<String, Object> stringObjectMap = inParamChange(poInfo);stringObjectMap.putAll(PmsPdfFieldEnum.getMap());log.info("json: {}", JSONUtil.toJsonStr(stringObjectMap));Configuration freemarkerCfg = new Configuration(Configuration.VERSION_2_3_28);freemarkerCfg.setTemplateLoader(new ClassTemplateLoader(ExcelServiceImpl.class, "/template/"));Template template = freemarkerCfg.getTemplate("pdf.html");StringWriter out = new StringWriter();template.process(stringObjectMap, out);String html = out.toString();PdfDocument pdf = new PdfDocument(new PdfWriter(output));pdf.setDefaultPageSize(PageSize.A4);Document document = HtmlConverter.convertToDocument(html, pdf, getConverterProperties());document.getRenderer().close();document.close();MultipartFile multipartFile = MultipartFileUtils.buildFileClientFile(String.format("%s_%s.pdf", poInfo.getCode(), poInfo.getCurrentVersion()), output.toByteArray());// 文件上传fastDFS再返回文件地址return fileService.upload(multipartFile, userService.getCurrentUserDto().getUserAccount());} catch (Exception e) {log.info("生成pdf异常:", e);throw new BizException(I18nStaticEnum.static_text_112381.code);}}

getConverterProperties()原代码：

    /*** 解决中文字体问题* @return* @throws Exception*/private ConverterProperties getConverterProperties() throws Exception {ConverterProperties props = new ConverterProperties();FontProvider fontProvider = new FontProvider();PdfFont sysFont = PdfFontFactory.createFont("STSongStd-Light", "UniGB-UCS2-H", false);fontProvider.addFont(sysFont.getFontProgram(), "UniGB-UCS2-H");fontProvider.addStandardPdfFonts();fontProvider.addFont("template/font/simsun.ttc");fontProvider.addFont("template/font/STHeitibd.ttf");props.setFontProvider(fontProvider);props.setCharset("utf-8");return props;}

getConverterProperties()修改后的代码：

    /*** 解决中文字体问题* @return* @throws Exception*/private ConverterProperties getConverterProperties() throws Exception {ConverterProperties props = new ConverterProperties();FontProvider fontProvider = new FontProvider();// 一定要注释这里，就是UniGB-UCS2-H这个编码格式和泰语编码格式不兼容
//        PdfFont sysFont = PdfFontFactory.createFont("STSongStd-Light", "UniGB-UCS2-H", false);
//        fontProvider.addFont(sysFont.getFontProgram(), "UniGB-UCS2-H");fontProvider.addStandardPdfFonts();fontProvider.addFont("template/font/simsun.ttc");fontProvider.addFont("template/font/STHeitibd.ttf");fontProvider.addFont("template/font/STSONG.TTF"); //华文宋体fontProvider.addFont("template/font/NotoSansThai.ttf"); //泰语字体props.setFontProvider(fontProvider);props.setCharset("utf-8");return props;}
