需要使用中文字体, 这里使用微软宋体. html转pdf中, fontResolver.addFont 加载字体 html中, body 需要指定使用的字体, <body style="font-size:12.0pt; font-family:SimSun;"> 注意字体名称(不是字体文件名),
读html 写pdf的编码需要统一
需要遵守严格的html规范(每个标签必须闭合), 样式最好写到Html 标签里 XHTML 定义不是必须的, 这样写为了以防万一
html中
&转义字符, 需要手动转义
sb.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">\n");
sb.append("<html lang=\"zh\" xmlns=\"http://www.w3.org/1999/xhtml\">\n");
sb.append("<body style=\"font-size:12.0pt; font-family:SimSun;\">\n");
sb.append("<p>你好</p>");
sb.append("</body>\n");
sb.append("</html>\n");
你没有真正将png转换为pdf,但创建了一个带有png的pdf. Document document = new Document(PageSize.A4, 20, 20, 20, 20); PdfWriter.getInstance(document, new FileOutputStream(“C:/test.pdf”)); document.open(); Image image = Image.getInstance(getClass().getResource(“/logo.png”)); document.add(image); document.close();
