Question

我有这段代码

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ page trimDirectiveWhitespaces="true" %>
    <%@page import="com.itextpdf.text.Document"%>
    <%@page import="com.itextpdf.text.Paragraph"%> 
   <%@page import="com.itextpdf.text.PageSize,java.sql.Blob"%>
   <%@ page import="javax.servlet.http.*,javax.servlet.*,com.itextpdf.text.DocumentException" %>
   <%@page import="java.io.*,java.text.SimpleDateFormat"%>
   <%@page import="java.sql.*,java.nio.charset.Charset,com.itextpdf.text.pdf.BaseFont"%>
   <%@ page import="com.itextpdf.tool.xml.ElementHandler,java.util.List,java.util.Arrays,java.util.Collections,java.util.*,com.itextpdf.text.pdf.*,com.itextpdf.tool.xml.ElementList,com.itextpdf.text.Rectangle,com.itextpdf.text.Element,com.itextpdf.text.*,com.itextpdf.text.Font,java.awt.Color,com.itextpdf.text.Font.FontFamily,java.util.Date,java.text.*,com.itextpdf.tool.xml.XMLWorkerHelper" %>

Class.forName("com.mysql.jdbc.Driver");

request.setCharacterEncoding("UTF-8");
String date=request.getParameter("user");

OutputStream output=response.getOutputStream();
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "inline; filename=details.pdf");
try{
    Document document = new Document(PageSize.A4, 20, 20, 130, 20);
PdfWriter writer=PdfWriter.getInstance(document, output);
document.open();
BaseFont bf = BaseFont.createFont("c:/windows/fonts/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
writer.setPageEvent(new HeaderAndFooter(date));
XMLWorkerHelper worker = XMLWorkerHelper.getInstance();
List arrlist = new ArrayList();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/gla", "root", "root");
Statement st=con.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs=st.executeQuery("SELECT * FROM user_start2 where date='"+date+"' ");
 while(rs.next()){
 arrlist.add(rs.getString("data"));
 }
InputStream is=null;
 for(int i=0;i<interval+1;i++){
  String str =(String) arrlist.get(i);
StringBuffer sb=new StringBuffer(); 
sb.append(str+"<br />");
String ss=sb.toString(); 
is = new ByteArrayInputStream(ss.getBytes());
  worker.parseXHtml(writer,document,is);
}
is.close();
writer.flush();
writer.close();
document.close();
}catch(IOException e){e.printStackTrace();}
output.close();
%>
</body>
</html>

上面的代码给了我这个结果 enter image description here

正如你在图片中看到的那样，它完全显示英语，但对于印地文字体，它会显示????? 我也尝试用这一行添加字符编码

is = new ByteArrayInputStream(ss.getBytes("UTF-8"));

但它给了我输出 enter image description here

以前我只使用没有xmlworker的itext，它在pdf上给了我正确的印地文字体，但是因为使用xmlworker我得到????或垃圾值。

如果我需要提供更多数据，请告诉我。

Xmlworker显示垃圾/ ???而不是印地文字体
