重命名由Java Servlet流传输的PDF [英] Renaming a PDF streamed by Java Servlet

问题描述

使用XSLT，XSL-FO和Apache FOP的正确组合，我可以将PDF发送到某些浏览器窗口。

其实我发送的文件内容如下：

Using the right mix of XSLT, XSL-FO and Apache FOP, I am able to send a PDF into some browser window.
In fact, I am sending the file content as follows:

           response.setContentType("application/pdf");
            response.setContentLength( out.size());
            response.getOutputStream().write( out.toByteArray());
            response.getOutputStream().flush();

如预期的那样，浏览器会在名为pdf的选项卡中显示PDF内容，如果我在本地保存文件，默认为pdf.pdf

如何强制文件名？

As expected, the browser shows the PDF content in a tab named "pdf", and if I save the file locally, the name also defaults to pdf.pdf
How can I force the file name?

我尝试过以下其他方面没有工作：

I tried the following among other things that didn't work:

           response.setHeader("Content-Disposition","inline; filename=" + filename + ".pdf" ); 

为了清楚起见，我想在浏览器中显示内容（而不是直接下载）

For clarity I want to display the content in the browser (as opposed to a straight download)

推荐答案

我发现解决方案这里

基本上，这是更改web.xml中的URL模式

浏览器将使用任何页面名称看起来像

我曾经有

Basically, it's a matter of changing the URL pattern in web.xml
The browser will use whatever the page name looks like
I used to have

<servlet-mapping>
        <servlet-name>PDF</servlet-name>
        <url-pattern>/pdf</url-pattern>
    </servlet-mapping>

我替换为

<servlet-mapping>
        <servlet-name>PDF</servlet-name>
        <url-pattern>/pdf/*</url-pattern>
    </servlet-mapping>

使用 http：//wherever/pdf/filename.pdf调用servlet ？param1 = va1 ... 将文件名更改为filename.pdf

Invoking the servlet using http://wherever/pdf/filename.pdf?param1=va1... changes the file name to "filename.pdf"
