如何显示为iText生成的PDF另存为对话框？ [英] How to show a Save As dialog for a iText generated PDF?

问题描述

当我发送由iText在servlet中生成的PDF文件时，我想显示一个<另存为对话框。我如何才能实现这一点？

解决方案

我在此页面上找到：
http：//www.geek-tutorials .com / java / itext / servlet_jsp_output_pdf.php

该方法是直接用getOutputStream（）（而不是文件路径）写入，并发送内容类型标题！

  response.setContentType（application / pdf）; 
 Document document = new Document（）; 
 try {
 PdfWriter.getInstance（document，
 response.getOutputStream（））; 
 // pdf生成代码
  

这么简单...

I want to show a Save As dialog when I send the PDF file which is generated by iText in a servlet. How can I achieve this?

解决方案

Ok I solved my problem!! I found on this page : http://www.geek-tutorials.com/java/itext/servlet_jsp_output_pdf.php

The method is to write directly with getOutputStream() (not in file path) and send content type header!

response.setContentType("application/pdf");
Document document = new Document();
try{
    PdfWriter.getInstance(document, 
    response.getOutputStream());
    //pdf generate code

It was so simple...
