请记住，word转换如果没问题，那么就要设置pdf的字体，这个是铁律！

### 核心配置代码 ###

将PdfOptions提出来作为方法使用

private PdfOptions getPdfOptions() {
            PdfOptions pdfOptions = PdfOptions.create();
            // 解决中文不显示问题
            pdfOptions.fontProvider(new IFontProvider() {
                @Override
                public Font getFont(String familyName, String encoding, float size, int style, Color color) {
                    try {
                        File file = new File(pdfChineseTTF);
                        Preconditions.checkState(file.exists(), "中文字体文件不存在:" + pdfChineseTTF);
                        BaseFont bfChinese = BaseFont.createFont(pdfChineseTTF, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
                        Font fontChinese = new Font(bfChinese, size, style, color);
                        if (familyName != null) {
                            fontChinese.setFamily(familyName);
                        }
                        return fontChinese;
                    } catch (Throwable e) {
                        e.printStackTrace();
                        // An error occurs, use the default font provider.
                        return ITextFontRegistry.getRegistry().getFont(familyName, encoding, size, style, color);
                    }
                }
            });
            return pdfOptions;
        }

### PDF下载流问题 ###

注意前端PDF文件流空白问题参考以下方案进行处理

[js下载PDF文件流，打开空白问题\_使用jspdf导出服务器上pdf文件的时候文件里面没有内容\_夏小锋的博客-CSDN博客][js_PDF_jspdf_pdf_-CSDN]

[前端下载二进制流pdf文件，下载成功，打开空白问题解决\_前端下载pdf文件流打开空白\_Helen\_fight的博客-CSDN博客][pdf_pdf_Helen_fight_-CSDN]

### WPS模板问题 ###

使用wps处理的template.docx文件不能识别到页脚信息，请使用微软提供的office进行编辑

以下是WPS footer xml部分，不是OOXML需要的解析范式：

<pkg:part pkg:name="/word/footer1.xml" pkg:contentType="application/vnd.openxmlformats-officedocument.wordprocessingml.footer+xml">
