How do you open a PDF in a new tab and show it in the browser (don't ask to download)?

I have a link to a PDF and when I click on it I want it to open a new tab and render in the new tab as opposed to asking me to download it. How do I do that?

note, I'm asking this question so I can answer it. This information can be pieced together from other answers, but I'd like it to be all in one place

The secret is using InputStreamResource in method response instead as ResponseEntity:

@GetMapping(path = "/pdf/{key}", produces = MediaType.APPLICATION_PDF_VALUE)
@ResponseBody
public InputStreamResource pdf(@PathVariable("key") String key){
    InputStream file = pdfservice.get(key);
    return new InputStreamResource(file);
}

To open a link in a new tab (PDF or not) you must modify the HTML of that link from

<a href="/link_to_pdf.pdf">PDF</a>

to

<a href="/link_to_pdf.pdf" target="_blank">PDF</a>

To open a PDF in the browser you must make a server side change to the response header. In Java, you would do this:

response.setContentType("application/pdf");
response.addHeader("content-disposition", "inline; filename=link_to_pdf.pdf");

Of key importance is the inline. If you put attachment, your browser will try to download it instead. You can read more here.
