As you have to set the response type with the following configuration:-
因为您必须使用以下配置设置响应类型：-
File outPutFile=new File(generatedFile);
stream = response.getOutputStream();
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "inline; filename=\"" + filename + "\"");
response.setContentLength((int) outPutFile.length());

you need this:
你需要这个：
response.setContentType("application/pdf")
response.setHeader("Content-Disposition", "inline; filename= .. " )
Otherwise, the browser will prompt you to open/save. ( if content type is octet-stream, or content-disposition is attachment )
否则，浏览器会提示您打开/保存。（如果内容类型是八位字节流，或内容处置是附件）
if you want the pdf to be displayed in a tab, you need to set target = "_blank" in the html ( or angular, jsp, whatever framework you are using ).
如果您希望 pdf 显示在选项卡中，则需要在 html（或 angular、jsp、您使用的任何框架）中设置 target = "_blank" 。
