Java Spring MVC display PDF in browser

问题:

How do I force the browser to display the pdf instead of downloading ? Here is the controller

 @RequestMapping(value = "/preview.pdf", method = RequestMethod.GET)
protected String preivewSection(      
    HttpServletRequest request,
        HttpSession httpSession,
    HttpServletResponse response) {
    try {
        byte[] documentInBytes = getDocument();         
        response.setHeader("Content-Disposition", "inline; filename=\"report.pdf\"");
        response.setDateHeader("Expires", -1);
        response.setContentType("application/pdf");
        response.setContentLength(documentInBytes.length);
        response.getOutputStream().write(documentInBytes);
    } catch (Exception ioe) {
    } finally {
    }
    return null;
}

If you remove this line, the pdf will open in the browser itself.

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

It looks like the above mentioned controller is all we need from the server side, the problem is the browser doesn't support viewing PDF files.

Use this google chrome browser not support preview It.

response.setHeader("Content-Disposition", "attachment; filename=" + file.getName());

But I changed this header as :

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

preview ok !

Because inline (default value, indicating it can be displayed inside the Web page, or as the Web page)
