public static void dwgToPdf (String uuid, String fileName, String fileExtension) throws IOException

// 根据uuid得到文件在服务器的存储路径
String zipFilePath = StringUtils.format(“{}/{}”, getUploadPath(), uuid);

    // 如果文件不存在抛出异常

        {
            throw new FileNotFoundException("文件异常!");
        }
        if(headers.stream().anyMatch(x -> x.getFileName().toLowerCase().endsWith(".pdf")))

            PdfOptions pdfOptions = new PdfOptions();

            {
                zipFile.addStream(bis2, parameters);
            }
            catch (Exception e)
            {

@dream.xg,
你好。
您需要指定每个 SHX 字体文件的路径：

...
cadRasterizationOptions.setShxFonts( new String[] {
		"pathTo\\bigfont.shx",
		"pathTo\\txt.shx",
});
...
