springboot 返回pdf流文件怎么在浏览器显示自定义的title

Question

@RequestMapping(path = "/file", method = RequestMethod.GET)
public void test(HttpServletResponse response) throws IOException {
    String str ="D:/1.pdf";
    FileInputStream fileInputStream= new FileInputStream(str);
    response.addHeader("Content-Disposition", "attachment; filename=" + str.substring(str.lastIndexOf("/") + 1));
    response.setContentType("application/pdf");
    byte[] bytes = new byte[fileInputStream.available()];
    int i;
    if ( (i = fileInputStream.read(bytes)) > 0){
        response.getOutputStream().write(bytes, 0, i);
    }
}

这种方式浏览器显示的title就是 file，而不是1.pdf，请问怎么才能让它显示成自定义的标题呢？

response.addHeader("Content-Disposition", "attachment; filename=" + str.substring(str.lastIndexOf("/") + 1));

这个定义用在下载文件上的，我把attachment改成inline也显示不出来
