==中文字体：==
1.使用Windows系统字体(TrueType)
BaseFont baseFont = BaseFont.createFont("C:/Windows/Fonts/SIMYOU.TTF", BaseFont.IDENTITY_H,
BaseFont.NOT_EMBEDDED);
2.使用自己的资源字体 (需要放在classpath下)
BaseFont baseFont = BaseFont.createFont("/SIMYOU.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
3.使用iTextAsian.jar中的字体 （==有效==）
BaseFont baseFont = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
通过上述基本字体，构造itext的Font类：
demo:
@Test
public void testCreateSimplePdf2() {
Document document = new Document();
PdfWriter pdfWriter = null;
try {
pdfWriter = PdfWriter.getInstance(document, new FileOutputStream("D:/中文支持.pdf"));
// 中文字体支持
BaseFont baseFont = BaseFont.createFont
("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
Font font = new Font(baseFont);
// 文档基本属性
document.open();
document.addAuthor("wx");// 作者
document.addTitle("PDF生成测试"); // 标题
document.addSubject("this is subject"); //主题
document.addKeywords("Keywords"); //关键字
document.addCreationDate();//创建时间
document.addCreator("LOL");// 创建程序
// 创建一个段落
Paragraph paragraph = new Paragraph("让iText生成的PDF支持中文字体",font);// 段落
// 将段落加入文档中
document.add(paragraph);
} catch (DocumentException | IOException e) {
e.printStackTrace();
} finally {
// 释放资源
document.close();
assert pdfWriter != null;
pdfWriter.close();
}

}Tips:
单元格文本居中问题：
一般情况：
水平居中： cell.setHorizontalAlignment(Element.ALIGN_CENTER);
垂直居中： cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
但有时不生效：
垂直不生效：
先调用cell.setUseAscender(true); //设置可以居中
再调用cell.setVerticalAlignment(Element.ALIGN_MIDDLE);// 设置垂直居中
水平不生效：
单独设置该单元格的文本居中：
PdfPCell cell1OfFirstRow = new PdfPCell();
cell1OfFirstRow.setColspan(2);
Paragraph p = new Paragraph("疫苗种类", font);
p.setAlignment(Element.ALIGN_CENTER);//直接设置内容：可解决水平居中，但无法解决垂直居中
cell1OfFirstRow.addElement(p);
// 1.创建itext中的图片类
Image image = Image.getInstance("C:/image/test.jpg"); // 图片的路径
// 2.可设置图片的属性
// 设置图片位置: 以pdf页面为基准，x轴和y轴从页面左下角开始为0点定位。
image.setAbsolutePosition(100f, 550f);
// 设置图片的宽度和高度
image.scaleAbsolute(400, 200);
// 3.将图片加入文档中
document.add(image1);步骤：
1.首先，直接根据数据和样式要求，编写html代码
2.然后，通过 XMLWorkerHelper.getInstance().parseXHtml(...);将html解析成PDF

XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, document, b,null,

Tips:
html标签一定要==全闭和==，否则报 the document has no pages
样式问题
不够灵活，一个PDF文档就需要编写一个html页面
对html+css有一定要求
主要思路是，使用 com.itextpdf.tool.XmlWorker包下的Api
可配合网页静态化技术一起使用：freemarker+itext
// 通过自定义函数，获取生成静态化页面的字符串
String html = translateFtlToHtml("test.ftl", modelMap);
XMLWorkerHelper.getInstance().parseXHtml(writer, document, new StringReader(html));生成静态化页面，并返回其字符串
<!DOCTYPE html>

</html>将html页面转换成ftl模板：

try {
Configuration configuration = new Configuration(Configuration.getVersion());
// 模板所在的目录
configuration.setDirectoryForTemplateLoading(new File("resources/templates"));
// 模板的字符编码

// 根据模板名获取指定模板
Template template = configuration.getTemplate(ftlFileName);
//
writer = new StringWriter();
// 填充数据
template.process(model, writer);
writer.flush();

} catch (IOException | TemplateException e) {
