    一、导入依赖

      <dependency>
                <groupId>com.itextpdf</groupId>
                <artifactId>html2pdf</artifactId>
                <version>4.0.0</version>
            </dependency>
            <!--        中文字体-->
            <dependency>
                <groupId>com.itextpdf</groupId>
                <artifactId>font-asian</artifactId>
                <version>7.2.0</version>
            </dependency>
    

    二、解决中文乱码问题

    /**
     * @description: html导出PDF支持中文,避免乱码
     * @author: chang
     * @create: 2021-11-04 14:25
     **/
    public class ChineseFontProvider extends XMLWorkerFontProvider {
    
        @Override
        public Font getFont(String fontname, String encoding, float size, int style) {
    
            try {
                BaseFont bfChinese = BaseFont.createFont("STSong-Light","UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);
    //            BaseFont bfChinese = BaseFont.createFont("STSongStd-Light","UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);
                return new Font(bfChinese,13,style);
                //            return new Font(bfChinese,size,style);
            }catch (Exception e){
                e.printStackTrace();
            }
            return super.getFont(fontname, encoding, size, style);
        }
    }
    

    三、由html字符串生成pdf

     public static void convertHtmlToPdf() throws IOException{
            String htmlStr = "<!DOCTYPE html>\n" +
                    "<html>\n" +
                    "<head>\n" +
                    "<meta charset=\"utf-8\">\n" +
                    "<title>文档标题</title>\n" +
                    "</head>\n" +
                    "<body>\n" +
                    "\t<h1>我的第一个HTML页面</h1>\n" +
                    "\t<p>我的第一个段落。</p>\n" +
                    "</body>\n" +
                    "</html>\n" +
                    "\n";
            Document document = new Document();
            try {
                PdfWriter writer = PdfWriter.getInstance(document,new FileOutputStream(FILE_BASE_PATH+"htmlToPDF.pdf"));
                document.open();
                XMLWorkerHelper.getInstance().parseXHtml(writer,document,new ByteArrayInputStream(htmlStr.getBytes(StandardCharsets.UTF_8)),null, Charset.forName("UTF-8"),new ChineseFontProvider());
                document.close();
            } catch (DocumentException e) {
                e.printStackTrace();
            }
        }
