iText中输出中文，有三种方式：

1、使用iTextAsian.jar中的字体

BaseFont.createFont(“STSong-Light”, “UniGB-UCS2-H”,BaseFont.NOT_EMBEDDED);

2、使用Windows系统字体(TrueType)

BaseFont.createFont(“C:/WINDOWS/Fonts/SIMYOU.TTF”, BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);

3、使用资源字体(ClassPath)

BaseFont.createFont(“/SIMYOU.TTF”, BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);

第2、三种方式使用的字体多一些，但是需要和实际资源绑定，在实际项目中可以将一些字体库和项目打包在一起，下面我们以iTextAsian中自带的字体为例说明如何输出中文：

BaseFont bfChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",
            BaseFont.NOT_EMBEDDED); 

Font FontChinese = new Font(bfChinese, 12, Font.NORMAL);
        document.add(new Paragraph(" 产生的报告",FontChinese));
