Question

我想在阿拉伯语中显示将通过mysql数据库生成的PDF报告。这是我的代码：

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub

    String relativeWebPath = "/font/A_Nefel_Adeti.ttf";
    String absoluteDiskPath = getServletContext().getRealPath(relativeWebPath);
    File file = new File(absoluteDiskPath);

    System.out.print(file);
 ByteArrayOutputStream output=new ByteArrayOutputStream();
 PDDocument document=new PDDocument();
 PDFont font = PDTrueTypeFont.load(document, new File(absoluteDiskPath),new WinAnsiEncoding());
PDPage test=new PDPage();
document.addPage(test);
 PDPageContentStream content=new PDPageContentStream(document, test);

final String EXAMPLE = "نديم";

System.out.print(EXAMPLE);

try{
     con=DBUtility.getConnection();
     stmt=con.prepareStatement("select * from login");
     rs=stmt.executeQuery();
     while(rs.next()){

         userName=rs.getString("UserName");
         password=rs.getString("Password");

        content.beginText();
         content.newLineAtOffset(50, 680);
         content.setFont(font, 12);
         content.showText(rs.getString("UserName"));
        // System.out.print(rs.getString("Password"));
         content.endText();


     }

 }catch(SQLException ex){
     ex.printStackTrace();
 }

 content.close();
 document.close();
   response.setContentType("application/pdf;base64,BASE_64_ENCODED_PDF");

response.addHeader("Content-Disposition", "inline; filename=\"TestReport.pdf\"");
response.getOutputStream().write(output.toByteArray());


}

它在控制台上显示阿拉伯文字，但PDF给出了这个错误：

输入例外报告

消息U + 0646在此字体的编码中不可用：WinAnsiEncoding

说明服务器遇到内部错误，导致＆gt;无法完成此请求。

异常

如果尚未完成，请更新至2.0。 javadoc有一个注释：

注意：简单字体仅支持256个字符。对于Unicode支持，请改用PDType0Font.load（PDDocument，File）。

这样做：

PDFont font = PDType0Font.load(document, new File(absoluteDiskPath);

这不适用于1.8或更早版本。
