Java Spring MVC在浏览器中显示PDF [英] Java Spring MVC display PDF in browser

问题描述

如何强制浏览器显示pdf而不下载? 这是控制器

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;
}

推荐答案

看起来上述控制器是服务器端所需的全部功能，问题在于浏览器不支持查看PDF文件.

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.
