所需jar:

itext-1.00.jar

iTextAsian.jar

   // 创建一个Document对象

   //设置宋体
   BaseFont bfChinese = BaseFont.createFont("STSongStd-Light",
      "UniGB-UCS2-H", true);
   logger.info("test");

   logger.info("test1");

   try {
    //添加一些信息
    document.addTitle("历史交易记录查询结果");

    PdfWriter writer = PdfWriter.getInstance(document, ba);
