**原创部分**

*  建立Document对象的实例
    
    `Document document = new Document();`
 *  建立一个书写器(Writer)与document对象关联，通过书写器(Writer)可以将文档写入到磁盘中，filePath是pdf的生成路径

PdfWriter.getInstance(document, new FileOutputStream(
                            filePath));

*  新建一个字体，iText的方法STSongStf-Ligth 是字体，在BaseFont中设置之后，我们到处的pdf就可以兼容中文了。itext还有两种输出中文字体的设置，
    
     *  1 使用iTextAsian.jar中的字体

BaseFont bfChinese = BaseFont.createFont("STSongStd-Light",
                            "UniGB-UCS2-H", false);

-  2 使用Windows系统字体(TrueType)

> BaseFont.createFont(“C:/WINDOWS/Fonts/SIMYOU.TTF”, BaseFont.IDENTITY\_H,BaseFont.NOT\_EMBEDDED);

*  使用资源地址

>     BaseFont.createFont("/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
