Itext.jar 的版本是 5.0.5

往 c：/test.pdf 檔案寫入中文

Document doc = new Document(); FileOutputStream out = new FileOutputStream(new File("C:/test.pdf")); PdfWriter.getInstance(doc, out); //文字com/lowagie/text/pdf/fonts/ // BaseFont chinese = BaseFont.createFont("STSong-Light", // "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED); // BaseFont chinese = BaseFont.createFont("C:/windows/fonts/simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); BaseFont chinese = BaseFont.createFont(PdfTest.class.getResource("/") + "/simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); Font fontChinese = new Font(chinese, 12, Font.NORMAL); Paragraph text = new Paragraph("你好。。。。",fontChinese); doc.open(); // 開啟文件 doc.add(text); doc.add(text); doc.close();

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

若 BaseFont 如此定義 則會報一個

com.itextpdf.text.DocumentException: Font 'STSong-Light' with 'UniGB-UCS2-H' is not recognized.

Font 'STSong-Light' with 'UniGB-UCS2-H' is not recognized

還是不行，繼續研究，在網上前輩們說如下原因：

具體解決方法就是修改包的路徑了,詳細方法如下：

執行結果,OK,解決問題。

===========================

可以使用系統自帶的字型

BaseFont chinese = BaseFont.createFont("C:/windows/fonts/simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

或者 將simsun.ttc複製到 src 目錄下面；

BaseFont chinese = BaseFont.createFont(PdfTest.class.getResource("/") + "/simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

至此問題解決
