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();
}
}
