[FIXED] How to show PDF file using Spring Web application

Issue

I wish to show this file on page but this code make a direct download

<a th:href="@{/pdf/Manjaro-User-Guide.pdf}">Show Pdf file</a>

I'm using Spring-Thymeleaf

Thanks!

Solution

I found the solution by commenting the line below

//response.setHeader("Content-Disposition", "attachment; filename=\"demo.pdf\"");
   

Here is the code example:

@GetMapping(value = "/pdf")
    public void showPDF(HttpServletResponse response) throws IOException {
        response.setContentType("application/pdf");
        //response.setHeader("Content-Disposition", "attachment; filename=\"demo.pdf\"");
        InputStream inputStream = new FileInputStream(new File(rootLocation + "/Manjaro-User-Guide.pdf"));
        int nRead;
        while ((nRead = inputStream.read()) != -1) {
            response.getWriter().write(nRead);
        }
    }
