itextpdf-5.3.2.jar
单使用itextpdf-5.3.2.jar
包进行pdf操作是无法进行中文处理的
需要另外下载一个jar包:iTextAsian.jar
创建一个中文转换类:
import java.io.IOException; import com.itextpdf.text.DocumentException; import com.itextpdf.text.Font; import com.itextpdf.text.Paragraph; import com.itextpdf.text.pdf.BaseFont; public class PDFParagraph extends Paragraph{ private static final long serialVersionUID = -3007718914459085396L; public PDFParagraph(String content) { super(content, getChineseFont()); } private static final Font getChineseFont() { Font fontChinese = null; try { BaseFont baseFont = BaseFont.createFont("C:\\WINDOWS\\Fonts\\simhei.ttf", BaseFont.IDENTITY_H , BaseFont.EMBEDDED); fontChinese = new Font(baseFont, 12,Font.NORMAL); } catch (DocumentException e){ e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return fontChinese; } }
import java.io.FileOutputStream; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.itextpdf.text.Document; import com.itextpdf.text.DocumentException; import com.itextpdf.text.PageSize; import com.itextpdf.text.pdf.PdfWriter; public class PDFServlet extends HttpServlet { private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PDFParagraph chinese = new PDFParagraph("您好啊!"); Document doc = new Document(PageSize.A4); //建立一个文档对象 try { //建立一个书写器 PdfWriter.getInstance(doc,new FileOutputStream("F:\\test2.pdf")); //打开文档 doc.open(); //向文档中添加内容 doc.add(chinese); //关闭文档 doc.close(); } catch (DocumentException e) { e.printStackTrace(); } request.getRequestDispatcher("ok.jsp").forward(request, response); } }
[b]当方法运行到POST方法中时,将产生一个异常,
解决方案:
iText5.x版本以上中的font和encoding文件
都是从String RESOURCE_PATH = "com/itextpdf/text/pdf/fonts/" 加载
而老itextasian.jar包名是com.lowagie.text.pdf.fonts
包名不一致导致路径错误
所以需要修改jar包文件夹的命名改为:
com/itextpdf/text/pdf/fonts/ 目录结构
BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
如采用自带字库,将产生异常:
"Font 'STSong-Light' with 'UniGB-UCS2-H' is not recognized"
处理方式可以采用windos本地字库:
BaseFont bf = BaseFont.CreateFont("c:\\windows\\fonts\\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
这里要注意一点,C:\\WINDOWS\\Fonts\\simhei.ttf
在指定字库时,要确保该字体存在,在WINDOWS下面这个是默认路径
其他系统自行参考,可以双击字体文件查看标题名,也就是它的字体名称
如仍然使用英文字体,将依旧不能处理中文,此例采用的是simhei.ttf(黑体)[/b]
